Abstract: The Belgian terrestrial isopod fauna currently comprises 38 species, with only two from the family Philosciidae recorded until now. We report the first occurrence of Chaetophiloscia elongata (Dollfus, 1884) in Belgium, discovered in 2025 in a managed but microhabitat-rich garden in Brussels. This finding adds both a new species and genus to the Belgian fauna and represents a northward extension of the species’ known range in continental Europe, further supporting the ongoing expansion of Mediterranean isopods in anthropogenic environments outside their native range. A diagnostic key for Belgian Philosciidae is also provided.

Abstract: Trigonium zonatulatum (Greville) A. Mann, originally described as Triceratium zonatulatum Greville, was previously known solely from the Indo-Pacific, Indian Ocean, and Bering Sea. Here, we report the first record of this diatom species from the Atlantic Ocean (Caribbean Sea), based on material collected at Boca Chica Beach, Dominican Republic. A single valve was examined under light microscopy and agrees with Greville’s (1865) original and subsequent descriptions of T. zonatulum. This record substantially extends the known geographic distribution of this species and provides new evidence of its occurrence in the Caribbean Sea.

Abstract: We report 100 individuals of the Longfin Batfish, Platax teira (Forsskål, 1775), from the Mexican Pacific. Records include first reports from the Revillagigedo Islands and Michoacán, as well as additional sightings from Baja California Sur, Jalisco, Colima, Guerrero, and Oaxaca. Individuals included juveniles, subadults, and adults documented through diving, snorkeling, and one incidental fishery capture. The marked increase in records, including multiple individuals at different life stages, indicates that P. teira is becoming increasingly recurrent in the Tropical Eastern Pacific and suggests continued geographic spread and possible early population establishment.

Abstract: We report the first voucher-based record of Cyttarops alecto from the Chocó region of Ecuador. The specimen, an adult male captured at Reserva Tesoro Escondido, Esmeraldas Province, represents the second locality west of the Andes in South America and the first voucher-based record for the Ecuadorian Chocó. Identification was supported by external and cranial morphology and by COI and Cytb mitochondrial DNA. This record extends the distribution of C. alecto into a major Neotropical biodiversity hotspot and highlights the need for continued surveys in threatened Chocó forests.

Abstract: Vernonanthura almedae (H.Rob.) H.Rob. is an endangered species of the Cerrado domain, with its distribution previously documented only within the boundaries of the Federal District, Central-West Brazil. Herein, we report the first record of V. almedae in the state of São Paulo and extend the documented flowering and fruiting period of the species. We also document raphide shapes previously unreported for Vernonanthura. Our findings emphasise the need to revise herbarium collections and floristic surveys, as fundamental efforts for obtaining a more accurate understanding of species distributions and conservation.

Abstract: We report additional records of the recently described, supposedly rare species of wolf snake, Lycodon irwini Naveen et al., 2025, known only from Great Nicobar Island, India. We report 14 sightings of this species from opportunistic encounters recorded during sporadic surveys over seven months. This highlights the limited extent of previous surveys in this region and suggests that this species is not as rare as previously assumed. We also emphasise that Great Nicobar is a poorly surveyed area, and further rigorous surveys could yield more data on seemingly rare species and potentially reveal new ones from this region.

Abstract: We report range extensions for two species of caridean shrimp, Synalpheus pandionis Coutière, 1909 and Periclimenaeus perlatus (Boone, 1930), from the continental shelf off Bahia, Brazil. These records represent the southernmost occurrences for both species in the south-western Atlantic. Synalpheus pandionis was found associated with the sponge Mycale (Zygomycale) angulosa (Duchassaing & Michelotti, 1864), while P. perlatus was found associated with the sponge Aplysina fistularis (Pallas, 1766). We provide morphological diagnoses and DNA sequences (16S) for our South Atlantic specimens, contributing to the knowledge of their species’ biogeography and ecology.

Abstract: We report the first record of the recently described species Odorrana nagao Pham, Hoang, Nguyen, Nguyen, Ngo, Le & Ziegler, 2026 from China based on one specimen collected from Malipo County, Wenshan Prefecture, Yunnan Province. The morphological characteristics of specimen from China corresponds to the original description of the species and the sequence of it has a negligible genetic distance of 0.4% in the 16S rRNA gene with those of the type specimens of this species. This occurrence record extends the known distribution of this species by approximately 80 km northward.

Abstract: African records of Terpsinoë musica Ehrenberg are scarce and mainly restricted to North and West Africa, with previous East African reports limited to Ethiopia and fossil material from Kenya. Here, we extend the geographic distribution of this species in Africa by including two new observations in East and Southern Africa: the first observation of the species in Uganda (East Africa) was in the guts of Oreochromis leucostictus collected from Lake George. The observation from South Africa is based on material collected from the Nsikazi River. Light and scanning electron microscopy investigations confirmed the identification and revealed predominantly isolated frustules in the samples. These findings expand the known African distribution of T. musica and provide additional information on its morphology and ecology.

Abstract: The nasutiform wood-feeding termite Niuginitermes liklik Roisin & Pasteels, 1996 is recorded for the first time from the Philippines. The genus and species were originally described from Papua New Guinea, a distance of some 3,300 km from the new record. We compare external and internal characters of the soldier and large worker castes from the Philippines with the original description of N. liklik. To date, there are 54 described termite species present in the Philippines.

Abstract: Three specimens of Cheiracanthium furculatum Karsch, 1879 were found in lemon crops in the Campo de Cartagena subdivision of Murcia, Spain. These constitute the first records of the species in Spain. This species has been found before in other European countries where it has been linked to the importation of fruits and vegetables coming from various countries in Africa. However, these are the first records that are not strictly linked to imports, raising the question of whether the species may have become naturalised in the region.

Abstract: Two specimens of Thrissina adelae (Rutter, 1897), collected from Taiwan, were recently found in the ichthyology collection of the National Museum of Marine Biology and Aquarium. Because previous records of the species from Taiwan were all ambiguous, the present specimens represent the first reliable Taiwanese records for this taxon. However, the specimens were collected in 1964, and newer catches are unknown. Several other Taiwanese clupeiform species have not been recorded since the mid-20th century, suggesting that populations of these species have decreased in the region.

Abstract: Limnophila (Limnophila) japonica Alexander, 1913, a crane-fly species originally described from Japan, is newly recorded from China. Specimens were collected in Shaanxi province (Tongchuan, Weinan, Xianyang), China, during faunal surveys of Limoniidae. Morphological diagnostic characters, including wing pattern, body colouration, and male genitalia, are redescribed and illustrated. The discovery expands the known distribution of this species to continental East Asia and enriches the Chinese Limnophila fauna.

Abstract: We report the first peer-reviewed record of Lebiasina boruca (Bussing, 1967) (Characiformes, Lebiasinidae) from Panama. Specimens were collected in lowland streams of the Escarrea and Chico river basins, Chiriquí Province, on the Pacific slope in western Panama. This record extends the known distribution of the species south-eastward from southern Costa Rica and fills a distributional gap within the Chiriquí ichthyological province. The finding improves our current knowledge on the biogeography of Central American freshwater fishes and highlights the importance of surveys in relatively poorly studied transboundary drainages.

This is the second known locality of this species and the first record in Hunan Province. The new record extends the species’ distribution range approximately 200 km to the south. Phylogenetic reconstruction and uncorrected p-distances indicated subtle but distinct genetic differentiation between the newly discovered population and the topotypic population, highlighting the potential role of rivers and lowland plains in isolating populations of this species.

Abstract: The Golden Mussel, Limnoperna fortunei (Dunker, 1857), an invasive bivalve originating from Asia, has rapidly spread throughout South American river basins since its introduction around 1990. This study investigates the presence of L. fortunei in the middle stretch of the São Francisco River in Brazil. Sixteen collection stations were established along the river, spanning the municipalities of São Francisco, São Romão, Ibiaí, and Pirapora. Limnoperna fortunei was confirmed in all sampling locations within São Francisco and São Romão, constituting the first report of this invasive species in the middle São Francisco.

Abstract: Lampronycteris brachyotis (Dobson, 1879) is widely distributed throughout Neotropics. In Brazil, this bat species has been recorded in 26 localities in the Amazon, Cerrado, and Atlantic Forest ecoregions across 12 states. Here, we report the first occurrence in the state of Rio de Janeiro based on a capture of one individual in a secondary dense ombrophilous forest. This record fills a distributional gap of L. brachyotis within the Atlantic Forest, where previously records were from Paraíba, Bahia, Espírito Santo, São Paulo, and Paraná states.

Abstract: Argiope trifasciata is a nearly cosmopolitan orb-weaver whose presence in Europe has been documented only in recent decades. Here, we report the first records of the species from Greece, based on a collected voucher specimen from Rhodes, which was morphologically and genetically examined, and additional citizen-science observations from Rhodes, Kos, and Crete. The Rhodes sequence was identical to the Cyprus sequence across the 611-bp COI alignment, and the two sequences were recovered together within the strongly supported Old World-associated Clade. These records fill a distributional gap between the western and eastern Mediterranean, correspond to projections in GLM-based species distribution modelling and extend the documented range of A. trifasciata in the region. Given the possibility of both natural dispersal and human-assisted transport, we treat A. trifasciata in Greece as a cryptogenic, recently expanding species.

Abstract: Tarentola parvicarinata Joger, 1980 is a phyllodactylid gecko recently reported for the first time from the Grand-Bassam area of Côte d’Ivoire. Here, we document additional occurrences across the country based on reverified citizen-science photographs. We confirmed 15 records of T. parvicarinata that had previously been misidentified as other gecko species. The reverified data reveal a widespread distribution spanning major towns from southern to northern Côte d’Ivoire, indicating that the species has long been overlooked. Our findings refine the known distribution and status of this species and highlight the value of re-evaluating citizen-science datasets.

Abstract: We report four novel sites for Boulenophrys nankunensis (Wang, Li & Wang, 2020) that markedly expand this species’ previously known geographic range, which was thought to be restricted to the Nankunshan Provincial Nature Reserve in Guangdong Province, China. The new specimens facilitate a detailed morphological redescription of this species and supplement information on intraspecific phenotypic variation. We assess the conservation status of B. nankunensis and propose the of Endangered using IUCN criteria. This study provides morphological identification evidence and conducts the first formal extinction-risk assessment for this species.

Our records increase the number of confirmed localities in Goiás state from two to four and extend the known distribution by up to 350 km northeast, filling an important gap in the Central Brazilian Plateau. Most records were associated with gallery forests within the Cerrado matrix, highlighting the importance of riparian forest habitats as potential dispersal corridors for forest-associated species in open savanna landscapes.

Abstract: Three workers of the ant genus Gauromyrmex Menozzi, 1933 (Hymenoptera: Formicidae) were collected on Amami-Oshima Island, Japan, and identified as G. acanthinus (Karavaiev, 1935). This represents the first record of both G. acanthinus and the genus Gauromyrmex in Japan. We provide morphological features of the Japanese specimens and discuss the species’ distribution. Gauromyrmex acanthinus is broadly distributed across East and Southeast Asia, including China and Taiwan. This new record from Amami-Oshima suggests that G. acanthinus is also likely distributed across the Nansei Islands located between Amami-Oshima Island and these known localities. In addition, we propose the Japanese vernacular name “Katazuno-koukiari” for G. acanthinus.

Abstract: Xiphocolaptes falcirostris (Spix, 1824) is a broadly distributed bird species in the Caatinga biome; however, its populations are fragmented and restricted to well-preserved dry forests. From 2012 to 2025, 358 expeditions were carried out in 39 sampling units across areas of Caatinga in northeastern Brazil. Based on this effort, we report 17 new occurrence records of X. falcirostris at a spatiotemporal scale, which expand our understanding of populations within its geographic range. This is especially important for a species that has been threatened for several decades.

Abstract: Biological invasions threaten freshwater biodiversity, particularly in anthropogenically impacted ecosys-tems. We report the first record of the fish Xiphophorus hellerii Heckel, 1848 in the Piquiri river basin (Upper Paraná), which was found in recent surveys, and investigate its distribution in Brazilian streams, using secondary data. We recorded 19 individuals in the Piquiri river basin. The results indicate predominance of occurrences in metropolitan areas, totalling 76 records in Brazil, likely linked to aquarium releases. We hypothesize that channelized urban streams may facilitate establishment by increasing environmental stressors, and we highlight the risks to the native fish fauna by the invasive X. hellerii.

Abstract: We examined 35 sites across 24 rivers, lakes, and lagoons in El Salvador and documented two native and one non-native freshwater mussel species in addition to the invasive Corbicula. Phylogenetic analyses supported the synonymy of Nephronaias lempensis Marshall, 1926, under Nephronaias goascoranensis (Lea, 1858). Mussel distributions were patchy; Mycetopoda subsinuata (Sowerby, 1868) occurred in soft, lentic habitats, whereas N. goascoranensis occupied a broader range. Sinanodonta pacifica (Heude, 1878), a non-native species, occurred in the upper Lempa basin, and Corbicula showed recent expansion. These results provide essential data for conservation planning.

Abstract: Webspinners (Embioptera) are cosmopolitan but have limited dispersal abilities, and their occurrence data remain poorly documented in Japan. Oligotoma humbertiana (Saussure, 1896), a widely distributed tropical species, has previously been recorded in Japan only from Kyushu and Minamidaito Island, and its occurrence in the Yaeyama Islands has remained uncertain. Here, I report a verifiable specimen-based record from Iriomote Island, based on two winged males collected from a residential building. This finding suggests potential human-mediated dispersal, although local establishment cannot be excluded, and highlights the value of specimen-based data.

Abstract: From November 2025 to March 2026, we recorded the presence of the Twospot Livebearer, Pseudoxiphophorus bimaculatus (Heckel, 1848), as a non-native species in the Amarillo River sub-basin, Chiapas, Mexico. Specimens were found at 2,113 m above sea level in a drainage ditch connecting an artificial lagoon to an urbanized river in the municipality of San Cristóbal de Las Casas. We collected 327 individuals with standard lengths of 7–38 mm. The presence of multiple size classes, including juvenile specimens, indicates the establishment of a breeding population. This non-native species directly threatens the endemic, endangered Chiapas Killifish, Tlaloc hildebrandi (Miller, 1950).

Abstract: The eucalypt snout beetle genus Gonipterus Schoenherr 1833 (Coleoptera, Curculionidae) has been present in Uruguay since the 1930s, although the identity of the species remained uncertain. We confirm the presence of at least two species, G. platensis (Marelli, 1926) and G. pulverulentus Lea, 1897, using both morphological and mitochondrial COI analyses. Both species occur in commercial Eucalyptus plantation throughout the country. This represents the first molecular evidence of their coexistence in Uruguay, providing key information for future management and biological control programs in eucalypt forestry.

Abstract: Myotis peytoni Wroughton & Ryley, 1913, a species of bat endemic to the forests of South India, is categorized as Data Deficient. Here, we report a new country record from Bangladesh, approximately 2,000 km north of this species’ previously known distribution. A detailed study of morphology, including cranial and dental characters, as well as a molecular analysis using the cytochrome c oxidase subunit I gene, confirm the species as M. peytoni. The phylogenetic analysis shows that the individual from Bangladesh is closest to the south Indian population. We recommend further study of the biogeography and population dynamics of the Bangladesh population.

Abstract: The Mediterranean Mussel, Mytilus galloprovincialis Lamarck, 1819, is regarded by the federation as a high-risk invasive species in Mexico. Use of integrative taxonomy and niche modelling confirms mass aggregations in Ensenada harbour (Bahía de Todos Santos), Baja California, and forecasts this species’ presence in protected areas of the Gulf of California. While M. galloprovincialis is profitable in aquaculture, the economic benefit complicates efforts to evaluate and manage its invasive potential. This is the first detailed assessment of its non-native status in Mexican waters, and we emphasise the urgent need for a strategic plan to balance its economic advantages against environmental risks.

Abstract: Calcaritermes Snyder, 1925, is primarily a Neotropical termite genus, characterized by the soldier caste having a large, conspicuous spur on each foretibia. This character is absent in all other genera of the family Kalotermitidae. Calcaritermes colei Krishna, 1962 was described from soldiers collected at a single location in central Mexico. This termite is now recorded for the first time from Belize, Guatemala, and Honduras approximately 1,280 km from its type locality in Mexico.

Abstract: The distribution Barbarophryne brongersmai (Hoogmoed, 1972) has long remained poorly documented due to its resemblance to Bufotes boulengeri (Lataste, 1879). The species had long been considered as endemic to Morocco until its presence was reported from Algeria, but without supporting evidence. We report the first documented observation from Algeria based on a population discovered in the Béchar region in May 2025. Multiple individuals at different life stages were observed. This record confirms the species’ presence in Algeria and underscores the need for further surveys to refine its eastern distribution.

Abstract: During a year-long survey (October 2024–September 2025) in the King Abdulaziz Royal Reserve (KARR), eastern Saudi Arabia, nine vagrant bird species were recorded for the first time. These new regional records include Palearctic migrants and Afro-Asian visitors, extending known ranges across the Arabian Peninsula. Most species belong to Passeriformes and Charadriiformes, reflecting terrestrial and wetland habitats. The results highlight KARR’s importance as a refuge for migratory and vagrant birds and emphasize its global conservation value under climatic aridification.

Abstract: Fruit flies have been intensively studied in Rio Grande do Sul (RS), Brazil, given their importance in temperate fruit production. Consequently, several fruit-fly surveys using McPhail traps have been conducted in fruit production hubs, revealing Anastrepha Schiner, 1868 diversity in the state. However, the association of fruit flies with host plants remains poorly known. In this note, we report for the first time Anastrepha consobrina (Loew, 1873) and A. punctata Hendel, 1914 in RS, both collected in traps. A key to the Anastrepha species recorded in the state is also presented.

Abstract: The Japanese Red Fox, Vulpes vulpes japonica Gray, 1868, is highly adaptable, yet its urban ecology in Japan remains poorly documented. We conducted a camera-trap survey in an urban green space in Kyoto between July 2023 and November 2025 and recorded 14 detections, all occurring from October to January. This seasonal pattern suggests repeated use of the site during the breeding period, likely as part of a larger annual home range. Our findings underscore the need for broader urban wildlife research across Japanese cities that accounts for structural and historical traits.

Abstract: Natrix tessellata (Laurenti, 1768) (Reptilia, Colubridae) was encountered in two localities from southern Romanian Moldavia. In 2022, we observed a road-killed individual near a tributary of the Siret River. In August 2024 and August 2025, we observed 18 living individuals at Cosmești on the east bank of the Siret River, about 80 km upstream from the previously known distribution records at the confluence between the Siret and the Danube. The N. tessellata individuals from Cosmești appear to favour stones of the riprap banks and the availability of gobies for food.

Abstract: Neottia furusei T. Yukawa & Yagame (Orchidaceae) is a critically endangered mycoheterotrophic orchid that is endemic to Japan. We report on a new locality in the northwestern Hidaka Mountains, Hokkaido. This represents the second record in the Hidaka region and the species’ westernmost limit in Hokkaido, extending its known range by 65 km north-northwest and 15 km west. We consolidated 16 records in Hokkaido using field surveys, published literature, and biodiversity occurrence databases (GBIF and S-Net). Our findings improve the understanding of the distribution and habitat of this rare orchid, essential for its conservation.

Abstract: We present the first confirmed records of Roger’s Racer, Platyceps rogersi (Anderson, 1893), from Lebanon based on records from the semi-desert region of the northern Beqaa Valley. The species’ presence in the country is supported by photographic evidence from three well-documented individuals, two of which were also genetically confirmed, corroborating the expected occurrence of the species as well as previous unofficial reports from local people in the area. This finding, together with our updated checklist, increases the number of colubrid snake species known from Lebanon to 16 and underscores the need for continued surveys in the region, particularly during different times of the year, including months outside the main field season.

Abstract: Slovakia is located on the edge of the distribution ranges of Chrysops divaricatus Loew, 1858 and Tabanus paradoxus Jaennicke, 1866. The recent occurrence of both species was confirmed after more than five decades, with records in the same geomorphological units previously known. Chrysops divaricatus is distributed in the northern regions of Europe and Asia and may represent a post-glacial relict in Slovakia. Conversely, T. paradoxus is characteristic of southern Europe, with no evidence of range expansion.

Abstract: Zomicarpella maculata N.E.Br. (Araceae, Caladieae) a rare species previously known only from Cuzco, Peru, is here recorded for the first time from Brazil. The species was found in a semi-deciduous forest within the Estação Ecológica da Serra das Araras, Mato Grosso. This represents an eastward range extension of over 1,500 km. Diagnostic morphological characters, habitat information, taxonomic notes, and an updated distribution map are provided. This finding significantly expands the species’ range and underscores the critical role of protected areas in conserving rare taxa.

Abstract: The rediscovery of the Ogasawaran endemic wasp Isodontia boninensis (Tsuneki, 1973) is reported. This species has not been recorded since 1980. Individuals were collected from Ototo-jima in 2023–2025. No individuals were detected on the other surveyed islands. Two hypotheses to explain the long-term non-detection on anole-in-vaded islands are evaluated: prey limitation and nesting-cavity limitation. These island-level records are consistent with an invasion-history gradient and suggest that satellite islands not invaded by the Green Anole, Anolis carolinensis Voigt, 1832, may function as refugia for vulnerable insects and should be prioritized for multi-season monitoring.

Abstract: Maruca amboinalis (Felder, Felder & Rogenhofer, 1875) (Lepidoptera, Crambidae) was reared from larvae on the mangrove-associated vine Derris trifoliata Lour. in mangrove forests on Iriomote Island, Japan, providing the first confirmed evidence of its occurrence in mangrove habitats. Light-trap and citizen-science records from Japan, Taiwan, and India indicate a multivoltine life cycle and suggest broad ecological tolerance. Together with previous host records from Pongamia pinnata (L.) Pierre, our findings demonstrate the species’ adaptability to coastal legumes and emphasize mangroves as overlooked habitats supporting Indo-Pacific lepidopteran diversity.

Abstract: We report a new northernmost distributional limit for the polychaete Perinereis falklandica (Ramsay, 1914). Its previously known northern occurrence was in Chile at 18°28′S, and our new records, from 15°50′S, represents the first from Peru. Fifty-five specimens were collected in 2021, 2024, and 2025 from intertidal habitats at many localities in southern Peru and identified by their morphology. Differences in key traits compared to specimens from other latitudes are discussed. This finding suggests a continuous Chilean–Peruvian population in the marine Humboldtian ecoregion.

Abstract: Chilean Flamingo, Phoenicopterus chilensis Molina, 1782, inhabits the Andes and is listed as Near Threatened by the International Union for the Conservation of Nature. Denver Zoo Conservation Alliance and Junin National Reserve conducted field and drone surveys for P. chilensis in Lake Junin, Peru. Nests were found along muddy shorelines, with one area showing a high concentration of nests, chicks, and adult individuals. These results indicate significant temporal changes in population structure and nesting conditions, highlighting the utility of drone surveys for monitoring high-Andean waterbird colonies and informing conservation strategies for P. chilensis in this critical breeding habitat.

Although its presence was already known from the island of San Andrés, Colombia, we extend this species’ geographic range south to the Gulf of Morrosquillo. Based on 10 specimens collected between 2023 and 2024, its external diagnostic characteristics and, for the first time, its microstructures are documented. Finally, we provide an ontogenetic characterisation, focusing on external morphological traits that show significant variation.

Abstract: Daphnia retrocurva Forbes, 1882 (Crustacea, Cladocera, Daphniidae), a North American freshwater zooplankton species, was found in an artificial reservoir in central Japan. This represents the first record of D. retrocurva not only in Japanese and Asian freshwaters but also from outside North America. Our phylogenetic analysis based on mitochondrial DNA sequences revealed little differentiation between Japanese and North American populations. By combining geographical isolation and the lack of genetic differentiation, we consider Japanese D. retrocurva to be non-indigenous and relatively recently introduced.

Abstract: We documented the diversity of medium-sized and large terrestrial mammals at the Tres Mesas wind farm in Tamaulipas, Mexico. Monitoring was conducted over three years (July 2019–October 2022) using camera traps. We estimated diversity using Hill numbers (q = 0, 1, 2) and calculated the relative abundance index (RAI) to compare species abundance among sampling periods. We recorded 17 species of mammals, including three species of protected felids. Species richness (q0) did not differ significantly among sampling periods; however, diversity at orders q1 and q2 increased significantly during the third sampling period. Most species showed an increase in abundance, particularly herbivores. Although the Tres Mesas wind farm represents a partially modified landscape, it supports a mammal diversity comparable to that of nearby protected natural areas in the region. These results highlight the ecological importance of this site and its potential contribution to wildlife conservation in northeastern Mexico.

Abstract: Choreutis sexfasciella (Sauber, 1902), commonly known as the Banyan Leaf Skeletonizer Moth, is a non-native species in Europe associated with ornamental Ficus trees and has been recorded with increasing frequency in the Mediterranean region in recent years. We report the first confirmed occurrence of the C. sexfasciella in Greece. A larva collected in Rhodes (Dodecanese, Greece) was identified to species level by DNA barcoding, extending the known range of this introduced species into the eastern Mediterranean. This finding augments recent Mediterranean range expansions documented in neighbouring regions and highlights the value of molecular surveillance of non-native species.

Abstract: We report new records of Triplophysa strauchii (Kessler, 1874) from the middle Zeravshan river drainage in Uzbekistan. Previously, within this drainage, the species was known only from the upper reaches of this river in Tajikistan. Morphological and molecular (COI) analyses of specimens collected in 2022 and 2024 confirm that these specimens are conspecific with populations from the Syr Darya drainage. These findings document a significant westward range expansion of T. strauchii in the Zeravshan River. Specifically, the record from Narpay District represents the westernmost known limit of this species’ distribution, highlighting its continued westward expansion in Central Asia.

Abstract: Rhinolophus euryale Blasius, 1853 is a cave-dwelling species, whose occurrence in Abruzzo, Italy, has long remained uncertain. During monitoring activities carried out in a karstic cave located in Stiffe village (L’Aquila), we captured 34 bats, including 14 R. euryale. This record confirms this species’ presence in Abruzzo and highlights the importance of the site as a hibernaculum. Given the populations’ decline reported across the species’ range, these findings are crucial for conservation and underline the need for systematic surveys to monitor strictly protected bat species.

Abstract: The Andean-Amazonian Foothills is a biodiverse ecotone threatened by legal and illegal anthropogenic activities. We report for the first time three orchid species from this ecotone in Colombia. We propose that Baskervilla auriculata Garay and Brassia whewellii J.M.H.Shaw each have a has a conservation status of Least Concern, and that Epidendrum pucunoense Hágsater & Dodson is Vulnerable. We propose that all three species are Critically Endangered in Colombia, as each species is known from only a single population and each location exhibits habitat degradation. Our findings highlight the local biodiversity and the need for its conservation.

Abstract: The Andean Fox, Lycalopex culpaeus (Molina, 1782), is one of the largest endemic canids in South America. The northernmost part of its distribution lies in the Andes of southwestern Colombia, where it is known only from few localities. We present noteworthy records in southwestern Colombia, including one individual from the south-ern buffer area of Puracé National Park, a second individual found as roadkill on the Pan-American Highway, both in the Department of Cauca, and two additional records from the Colombian Massif. The Puracé record extents the distribution of this species by 74 km northward from previously verified localities.

Abstract: Freshwater mussels were surveyed in 32 sites across rivers, lakes, and lagoons in Honduras and five species (two Unionidae and three Mycetopodidae) confirmed. Anodontites tortilis and Mycetopoda subsinuata are reported for the first time from the country. Mussel distributions were patchy, with Caribbean drainages harboring only Nephronaias hjalmarsoni, while up to four species co-occurred in Pacific drainages. Phylogenetic analyses revealed polyphyly in Nephronaias and Anodontites, highlighting unresolved taxonomy. These results provide critical baseline data on species diversity, distributions, and conservation priorities for Honduras’ understudied freshwater mussel fauna.

Abstract: We report the first records of Panthera onca (Linnaeus, 1758) in Guanajuato, Mexico. These were observa-tions made within the Sierra Gorda of Guanajuato Biosphere Reserve from August 2024 to May 2025. Seventy-five camera traps documented 11 independent events of two individuals (one female, one male) in oak and tropical dry forests at elevations of 711–1,617 m. These findings fill a critical gap in validating Jaguar corridors across central and eastern Mexico and emphasize the role of protected and community-managed areas. We recommend expand-ing monitoring, strengthening local conservation agreements, and conducting genetic studies to assess regional connectivity.

Abstract: Twelve specimens of Hypoatherina temminckii (Bleeker, 1854) were collected from Bidong Island, off Terengganu in the southern South China Sea in July 2025. They represent the first report of this species from Malaysia, although the species is widely distributed in the Indo-West Pacific. Morphometric and meristic characters are described herein. Hypoatherina temminckii is distinguished by having body depth 13–19% of the standard length (SL), caudal-peduncle depth 5.7–7.6% of SL, the anus posterior to the pelvic-fin tip, the pectoral-fin axillary scale elongated posteriorly, vertebrae 39–43, midlateral scales 38–42, and a narrow interorbital width, 29–39% of the head length.

Abstract: The Brown-banded Cockroach, Supella longipalpa (Fabricius, 1798), is a synanthropic species of presumed African origin widely spread through human-mediated transport. We report the first verified record of S. longipalpa from Estonia and the Baltic countries, based on material collected indoors in a student dormitory in Tartu. The presence of adults, nymphs, and an ootheca indicates local completion of the life cycle. Identification was based on morphology and confirmed by DNA barcoding. This record extends the known distribution of the species in northern Europe.

Abstract: The Pacific chorus frog complex (Pseudacris spp.) includes three closely related species distributed from British Columbia to Baja California: P. hypochondriaca (Hallowell 1854), P. regilla (Baird & Girard 1852), and P. sierra (Jameson, Mackey, & Richmond, 1966), with only P. regilla recognized in Canada. We analyzed genetic sequence data from frogs in southeastern British Columbia and confirm the presence of P. sierra in Canada. These populations are likely contiguous with P. sierra in eastern Washington, Idaho, and Montana, extending the known range of the species northward.

Abstract: We report Microhyla ninhthuanensis Hoang, Nguyen, Ninh, Luong, Pham, Nguyen, Orlov, Chen, Wang, Ziegler & Jiang, 2021 for the first time in China, from Zhuhai and Zhongshan, Guangdong, based on the molecular and morphological evidence. This extends its geographic range northward and eastward by over 550 km and 500 km, respectively. The hypothesis that this species may have been recently introduced into China through human activities is also discussed based on the haplotype network analysis.

Abstract: Atelocynus microtis (Sclater, 1883) is a rare canid whose distribution spans the entire Amazon Basin. It is the least known canid in Colombia, where sightings have been reported from six localities. In contrast, Cerdocyon thous (Linnaeus, 1766) is the most common canid species in Colombia, with its distribution linked to open areas, human-modified landscapes, and agroecosystems. Here, we report new records of A. microtis and C. thous in the Colombian Amazon, documenting a range extension of C. thous and suggesting that forest loss driven by human activity may promote contact between these two otherwise allopatric canids.

Abstract: We present occurrence records of 93 bird species from the inter-Andean valley of Quito, Ecuador: the first vouchered country record of Indigo Bunting Passerina cyanea (Linnaeus, 1766); first records for 37 species in the Andes of Ecuador or within the inter-Andean valley; supplementary records of 45 species with scattered records; modern records for seven species; and reports of three non-native species. Several observations originate from novel urban habitats, underscoring the conservation potential of green infrastructure. The study highlights the pivotal role of participatory science in advancing our understanding of bird distribution.

Abstract: During recent fieldwork on Tenerife, several non-native plant species were recorded, some newly documented for the island and others as first records for the Canary Islands. These include fully established species like Brassica fruticulosa Cirillo, Crassula alata (Viv.) A.Berger, and Hydrocotyle sibthorpioides Lam., as well as casual species such as Bacopa monnieri (L.) Wettst. and Nephrolepis biserrata (Sw.) Schott. Many of these species have potential to naturalize or become invasive. Additional notes are provided on Biancaea decapetala (Roth) O.Deg. and Digitaria radicosa (J.Presl) Miq.

Abstract: Despite extensive research on biodiversity patterns, significant gaps remain in our understanding of species’ geographic distributions, representing a persistent Wallacean shortfall. The Godda Forest Division of Jharkhand state, located in the eastern part of India, remains largely unexplored with respect to amphibian diversity. In this study, we present the results of a six-month field survey conducted in the Godda Forest Division of Jharkhand spanning the summer and monsoon seasons. Phylogenetic analyses using 16S rRNA gene sequences were used to resolve the identification of taxonomically cryptic species. The survey documented 19 anuran species belonging to four families and 11 genera. These findings provide essential baseline information and underscore the need for systematic herpetofauna assessments across Jharkhand.

Abstract: During a survey of snake specimens in the Scientific Collection of Reptiles at the Universidade Comunitária da Região de Chapecó University on 10 December 2024, we reidentified a specimen previously labeled Liophis miliaris as Erythrolamprus semiaureus (Cope, 1862). This record, collected in Chapecó in 1986, extends the known distribution of E. semiaureus by 265 km northeast of the nearest previously known locality (Porto Xavier, Rio Grande do Sul). It represents the first occurrence of the species in the state of Santa Catarina, southern Brazil. We provide an updated distribution map and photographs of the preserved specimen.

Abstract: We document the first record of Vanellus resplendens (Tschudi, 1843) (Charadriidae) in Podocarpus National Park, southern Ecuador. On 15 May 2025, an adult was observed at 2,802 m a.s.l. in El Tiro (Abra de Zamora), Zamora Chinchipe. This record extends the species’ Ecuadorian range 60 km east from El Oro and 110 km south from Azuay, reduces the gap between northern and southern portions of its discontinuous Andean distribu-tion, and underscores the park’s importance for conserving high‑Andean bird assemblages.

Abstract: Oryzomys couesi (Alston, 1877) has a restricted geographic distribution in South America. Until now, it was only known from Montería, Córdoba, in the Caribbean region of Colombia. Here, we add three geographic records; a recent individual was recorded in Urabá, Antioquia, and during the identification process, we found six specimens from two localities around Isla de Salamanca National Park, Magdalena, whose identity have remained unpublished so far. These specimens represent additional geographic records of O. couesi in Colombia and South America. A cytochrome b sequence from the Urabá specimen increases the taxonomic and biogeographic relevance of these records.
