They arrived and don’t stop coming: an update on the distribution of exotic ants (Hymenoptera, Formicidae) in continental Ecuador https://checklist.pensoft.net/article/107171/ Check List 19(6): 801-819

DOI: 10.15560/19.6.801

Authors: Jefferson Salazar-Basurto, Adrián Troya, Francisco Romero, Alexander L. Wild, Alex Pazmiño-Palomino

Abstract: We present an updated list of introduced ants to continental Ecuador, and compile records of occurrence, as well as map the distribution of 15 exotic species. We analyzed specimens in entomological collections and data from AntWeb, GBIF and iNaturalist. Among these, we add two new records for the country: Cardiocondyla mauritanica Forel, 1980 and Pheidole megacephala (Fabricius, 1793). The former is also the first record for South America, while the finding of the latter shows how little we know about introduced tramp ants. In addition, we add site records for nine species: Cardiocondyla emeryi Forel, 1881, Cardiocondyla minutior Forel, 1899, Cardiocon­dyla wroughtonii (Forel, 1890), Linepithema humile (Mayr, 1868), Monomorium floricola (Jerdon, 1851), Monomo­rium pharaonis (Linnaeus, 1758), Paratrechina longicornis (Latreille, 1802), Tapinoma melanocephalum (Fabricius, 1793), and Tetramorium bicarinatum (Nylander, 1846). Based on our previous fieldwork observations, it appears that our understanding of exotic species richness is still in its early stages.

Confirmed presence of Clathrus columnatus Bosc (Phallales, Clathraceae) in the Galapagos Islands, Ecuador https://checklist.pensoft.net/article/110411/ Check List 19(5): 727-733

DOI: 10.15560/19.5.727

Authors: Justine Villalba-Alemán, Paúl Mayorga, C. Miguel Pinto, Patricia Jaramillo Díaz

Abstract: In July 2022, we collected three groups of Clathrus columnatus Bosc (Clathraceae) specimens (four mature and eight immature basidiomata) from Santa Cruz Island, Galapagos. We report these specimens as the first confirmed records of this species from the Galapagos Archipelago and Ecuador. We hypothesize that C. columnatus constitutes a recent introduction to the islands. We provide macro- and microscopic descriptions, including photographs of fresh and fluid-preserved basidiomata, and comments on the species’ taxonomy, ecology, and distribution.

New record of Azurina intercrusma (Evermann & Radcliffe, 1917) (Ovalentaria incertae sedis, Pomacentridae) and confirmation of Scuticaria tigrina (Lesson, 1828) (Anguilliformes, Muraenidae) in the Galápagos Islands https://checklist.pensoft.net/article/107554/ Check List 19(5): 611-620

DOI: 10.15560/19.5.611

Authors: William Bensted-Smith, Inti Keith, Jack Grove, Stuart Banks

Abstract: Herein we provide the first published records for Azurina intercrusma and a correction of previous Scuticaria tigrina records within the Galápagos Marine Reserve. The former had not previously been reported north of the southern Ecuadorian coastline and represents a significant step outside of its known distribution for this cold-water species. Scuticaria tigrina had been mentioned in previous literature as present, but its inclusion appears to have been in error; we confirm its presence as a vagrant and provide evidence of live observations in different parts of the archipelago.

Updated distribution of an alien frog species, Lithobates catesbeianus (Shaw, 1802), in Ecuador: new records of Bullfrog in the semideciduous lowland forest of western Ecuador https://checklist.pensoft.net/article/103090/ Check List 19(4): 533-539

DOI: 10.15560/19.4.533

Authors: Andrea E. Narváez, Marissa Barreno, Stefania Cuadrado, Katherine Vera, Natalia Molina-Moreira

Abstract: We report the occurrence of Lithobates catesbeianus (Shaw, 1802), Bullfrog, in a protected semidecidu-ous forest in the city of Guayaquil, Guayas, Ecuador and in a nearby wildlife management center. Bosqueira Pro-tected Forest is an isolated spot of diversity surrounded by urbanization, quarries, and highways. We found a juvenile Bullfrog in a water canal on the edge of the protected forest, near a private housing complex, and several tadpoles in an artificial pond in a wildlife management center located near the reserve. This is the first sighting of the invasive L. catesbeianus in a native ecosystem in Guayaquil. We also report the this species from, three other provinces of Ecuador, based on observations in iNaturalist. These records reinforce the ability of L. catesbeianus to adapt easily to varied environmental conditions and to disturbed areas. The invasion of L. catesbeianus towards semideciduous forest represents a new threat to biodiversity, particularly the endemic fauna, due to predation or competition. In future studies, it will be important to fully evaluate the Bullfrog diet and population status to esti-mate its impact on remnant forests of Guayaquil.

Amphibians and reptiles of Isla Santay (Durán, Ecuador) https://checklist.pensoft.net/article/98348/ Check List 19(3): 347-369

DOI: 10.15560/19.3.347

Authors: Keyko Cruz-García, Marissa Barreno, Stefania Cuadrado, M.D.M. Moretta-Urdiales, Natalia Molina-Moreira, Jaime A. Salas, Álvaro Torres-Domínguez, Andrea E. Narváez

Abstract: Amphibian and reptile diversity from Isla Santay (Durán, Ecuador) has been underestimated due to the lack of monitoring throughout the island. Historically, this island has also been affected by anthropic landscape changes which limit the occurrence of certain species and favors the dispersion of opportunistic or more tolerant species. Such species dynamics tend to be more evident on islands, since their isolation limits species’ mobility. We present an updated checklist of the herpetofauna of Isla Santay Durán, Ecuador, and report for the first time the occurrence of two introduced species, Anolis sagrei Duméril & Bibron, 1837, Brown Anole, and Hemydactylus frenatus Duméril & Bibron, 1836.

First record of Holothele longipes (L. Koch, 1875) (Araneae, Theraphosidae) from Ecuador https://checklist.pensoft.net/article/94643/ Check List 19(2): 141-145

DOI: 10.15560/19.2.141

Authors: Pedro Peñaherrera-R., Ariel Guerrero-Campoverde, Roberto J. León-E., Diego F. Cisneros-Heredia

Abstract: We present the first record of Holothele longipes (L. Koch, 1875) (Araneae, Theraphosidae) from the Republic of Ecuador, based on a male specimen collected near Puerto Misahuallí, province of Napo, in the north-eastern foothills of the Andes, upper River Napo basin. This new record extends the geographic range of H. longipes by approximately 554 km west of the nearest previously known locality, on the River Momón, department of Loreto, Peru. Our new record also represents the first time a species of the theraphosid subfamily Ischnocolinae has been found in Ecuador.

Diversity of small non-volant mammals of Lita, northwestern Imbabura, Ecuador https://checklist.pensoft.net/article/80515/ Check List 18(3): 709-719

DOI: 10.15560/18.3.709

Authors: Jenny Curay, David Mantilla, Jorge Brito

Abstract: The subtropical forests of the Pacific slope of Ecuador lie within a region of wide biodiversity due to the biogeographic influence of Chocó. However, the diversity of small non-volant mammals in these forests is poorly understood. We conducted surveys at seven localities in 2020 and 2021 in Lita, northwestern Imbabura province, Ecuador. Sampling was done on an altitudinal range of 1,314–1,812 m. We used a combination of techniques (Sherman, Tomahawk, and pitfall traps) to capture non-volant small mammals. Our accumulated trapping effort was 2,724 trap/nights. We recorded 180 individuals of 23 species, of which rodents were the most diverse with 17 species, representing 73.9% of the composition. The record of Pattonimus musseri Brito et al. (2020) stands out, representing both latitudinal and elevational altitudinal range extensions. Finally, our results indicate that Lita is a natural area with a high concentration of non-volant mammals in the northwestern Ecuadorian subtropics.

Elevational range extension of Drab Water Tyrant, Ochthornis littoralis (Pelzeln, 1868) (Passeriformes, Tyrannidae) https://checklist.pensoft.net/article/76966/ Check List 18(3): 451-453

DOI: 10.15560/18.3.451

Authors: Jefferson García-Loor

Abstract: The Drab Water Tyrant, Ochthornis littoralis (Pelzeln, 1868), is a small flycatcher occurring across lower Amazonia. Its usual habitat is the edges of rivers, and it is easily observed flying over sandbanks and among the trunks of fallen trees and branches. Here, I present a new locality in the Ecuadorian Andean foothills which represents a significant increase in this species’ elevational range from the Amazon lowlands. The new record is also from a previously unknown habitat for the species.

New distribution record of Bicolored Trailing Ant, Monomorium floricola (Jerdon, 1851) (Hymenoptera, Formicidae) from Ecuador, with information on cohabitation with the social spider Anelosimus eximius (Keyserling, 1884) https://checklist.pensoft.net/article/81360/ Check List 18(2): 399-404

DOI: 10.15560/18.2.399

Authors: Pablo Sebastián Padrón, Lucía Vanessa Ortiz, Pamela Estefanía Andrade, José Manuel Falcón, Anja Junghanns

Abstract: Invasive ant species are a serious threat to native fauna, especially in highly diverse tropical countries. Therefore, new distribution reports and information on the interactions with other species are essential to understand the potential effects of invasive ants on biodiversity. Here we report for the first time the presence of colonies of Monomorium floricola (Jerdon, 1851) in the nest of the Neotropical social spider Anelosimus eximius (Keyserling, 1884) in the southern part of the Ecuadorian Amazon. Our report extends the known distributional range of M. floricola to the southern Ecuador.

DOI: 10.15560/18.2.275

Authors: Franklin Vaca-Moyano, Paul L. Duque, Sandra Enríquez, Vanessa Herrera, Marco Sánchez-Murillo, Erika Rivadeneira, C. Alfonso Molina

Abstract: We report the first records of two mosquito species, Wyeomyia (Wyeomyia) abebela Dyar & Knab, 1908 and W. (Hystatomyia) coenonus Dyar & Knab, 1913, from the Choco Biosphere Reserve, a global biodiversity hotspot in Ecuador. We collected these mosquitoes in the Mashpi Lodge Reserve, a conserved natural area. Specimens were collected during their immature stages in bromeliads using a 375-ml absorber dropper. Our new data for W. abelela increases the geographical distribution of this species to include seven countries of America (Belize, Costa Rica, Guatemala, Honduras, Mexico, Panama, and Ecuador); W. coenonus is now known from two countries of America (Panama and Ecuador), and our records of W. abelela and W. coenonus are the first from South America.

Amphibians and reptiles of Wildsumaco Wildlife Sanctuary, Napo Province, Ecuador https://checklist.pensoft.net/article/58696/ Check List 17(3): 729-751

DOI: 10.15560/17.3.729

Authors: Jeffrey D. Camper, Omar Torres-Carvajal, Santiago R. Ron, Jonas Nilsson, Alejandro Arteaga, Travis W. Knowles, Brian S. Arbogast

Abstract: We conducted a long-term inventory of the herpetofauna of Wildsumaco Wildlife Sanctuary in the eastern part of the Napo Province in Ecuador. This private preserve is about 500 ha in size and is located on the southern slopes of Volcán Sumaco. The preserve contains primary forest, secondary forest, and pasture habitats. Based mostly on nocturnal transect sampling we documented 39 species of amphibians including one species of salamander, two species of caecilians, and 36 species of frogs. Rain frogs (Pristimantis Jiminez de la Espada, 1871) were diverse with 14 species documented. A diverse species assemblage of 45 reptile species was also documented on the preserve. Six amphibian species found were listed by the IUCN Red List. At least three species exhibited substantial geographic range extensions and seven species showed elevational range extensions. We discovered several undescribed species including one salamander, three frogs, one lizard, and one snake.

Report on the mammals of Quimsacocha National Recreation Area, Azuay Province, Ecuador https://checklist.pensoft.net/article/60952/ Check List 17(1): 125-131

DOI: 10.15560/17.1.125

Authors: Thomas E. Lee, Jr., Nicolas Tinoco, Seth C. Crockett, M. Alejandra Camacho, Santiago F. Burneo

Abstract: Quimsacocha National Recreation Area is located on the western slope of the Andes in Azuay Province, southern Ecuador. All sampling locations were in the high paramo and high Andean forests (3,572 to 3,865 m). The habitats include paramo, bogs, riparian, patches of elfin forests, and secondary cloud forest. We set Sherman, pitfall, and camera traps (3,600 trap nights), and mist nets to collect 117 specimens. Eight species were collected, including Caenolestes caniventer Anthony 1921; Didelphis pernigra J.A. Allen, 1900; Cryptotis montivagus (Anthony, 1921); Akodon mollis Thomas, 1894; Microryzomys altissimus (Osgood, 1933), Phyllotis haggardi Thomas, 1908; Sigmodon inopinatus Anthony, 1924; and Sylvilagus andinus (Thomas, 1897). Two additional species Coendou rufescens (Gray, 1865) and Odocoileus virginianus (Zimmermann, 1780) were documented photographically. This is the first survey that saved voucher specimens for mammals of Quimsacocha.

DOI: 10.15560/15.1.1

Authors: Omar Valencia-Méndez, Dave Catania, Andrés López-Pérez

Abstract: The Red-fin Goby, Evorthodus minutus Meek & Hildebrand, 1928, is a coastal brackish species which is commonly distributed from Sinaloa, Mexico to Guayaquil, Ecuador and particularly abundant in mangroves of Central American eastern Pacific. We report a new record of E. minutus collected from the Santa Cruz Island, part of the Galapagos Archipelago. This new record represents a range extension and is allows for a relevant discussion about colonization pathways in the equatorial eastern Pacific of a brackish-water species.

Noteworthy records of Sunbittern Eurypyga helias (Pallas, 1781) (Eurypygiformes, Eurypygidae) and Black-necked Stilt Himantopus mexicanus (Statius Müller, 1776) (Charadriiformes, Recurvirostridae) from the southern Andes of Ecuador https://checklist.pensoft.net/article/27560/ Check List 14(5): 801-804

DOI: 10.15560/14.5.801

Authors: Héctor Cadena-Ortiz, Juan Escobar, Juan Cordero, Edison Moreno, Gorki Ríos-Alvear

Abstract: We report the highest and southernmost documented records of 2 species of Ecuadorian birds: Sunbittern Eurypyga helias (Pallas, 1781) in the southern end of Podocarpus National Park and Black-necked Stilt Himantopus mexicanus (Statius Müller, 1776) in Yacuri National Park. Considering these and other records, both species might be expanding their ranges into the highlands, but the necessity to fill geographical, morphological, and taxonomic gaps on Ecuadorian birds remains.

New records of Diplomys labilis (Bangs, 1901) (Mammalia, Rodentia, Echimyidae) from Nicaragua https://checklist.pensoft.net/article/27583/ Check List 14(3): 555-558

DOI: 10.15560/14.3.555

Authors: José Gabriel Martínez-Fonseca, Fiona A. Reid, Julio Loza, Luis Gutiérrez-López, Javier Sunyer

Abstract: The Rufous Tree Rat Diplomys labilis is distributed from southwestern Costa Rica to northern Ecuador. We report the first 2 records of this species from southern Nicaragua, extending the known geographical distribution for the species about 280 km northward from its nearest known locality, in Costa Rica. We provide photos of both Nicaraguan individuals, which were observed almost a year apart in the same locality, the Refugio Bartola Private Reserve, Río San Juan Department.

Newly discovered population of Bumpy Glassfrog, Centrolene heloderma (Duellman, 1981), with discussion of threats to population persistence https://checklist.pensoft.net/article/20410/ Check List 14(1): 261-265

DOI: 10.15560/14.1.261

Authors: Katherine L. Krynak, Dana G. Wessels, Segundo M. Imba, Jane A. Lyons, Juan M. Guayasamin

Abstract: Since 2011, the Bumpy Glassfrog, Centrolene heloderma (Duellman, 1981) was known only from a single location in the Mindo region of Ecuador. We report a newly discovered population located in the area of La Sierra, along Río Alambi, a stream system used heavily for aquaculture of rainbow trout (Oncorhyncus mykiss). Threats to population persistence include anthropogenic habitat disturbances such as agriculture and aquaculture, and Batrachochytrium dendrobatidis infection. To improve conservation outcomes, we include notes on C. heloderma natural history, Batrachochytrium dendrobatidis susceptibility, and discuss possible mitigation strategies to protect the species.

Pyroderus scutatus masoni (Shaw, 1792) (Aves, Cotingidae): a subspecies of Red-ruffed Fruitcrow newly confirmed for Ecuador https://checklist.pensoft.net/article/21311/ Check List 14(1): 281-284

DOI: 10.15560/14.1.281

Authors: Leonardo Ordóñez-Delgado, Santiago Erazo, Ivonne González, Diego Armijos-Ojeda, Daniel Rosado

Abstract: We present the first records of the Red-ruffed Fruitcrow, Pyroderus scutatus (Shaw, 1792), in the Cordillera del Cóndor of Ecuador and the first confirmed records of this species in the east of this country. These new records were made in October 2016 and February and September 2017 in the Blanco river basin in southeastern Ecuador. This place is 200 km and over 500 km from the nearest occurrences of this species in Peru and Ecuador, respectively. We can now confirm the presence of the subspecies P. s. masoni (Ridgway, 1886) in Ecuador.

Annotated list of freshwater fishes of the Limoncocha Lagoon, Napo river basin, northern Amazon region of Ecuador https://checklist.pensoft.net/article/23352/ Check List 14(1): 55-75

DOI: 10.15560/14.1.55

Authors: Jonathan Valdiviezo-Rivera, Carolina Carrillo-Moreno, Enrique Gea-Izquierdo

Abstract: An annotated list of the freshwater fishes of the Limoncocha Lagoon, in the Limoncocha Biological Reserve in the northern Amazon region of Ecuador is presented. Fishes were captured between March and July of 2012, and we combined these results with previous studies to provide a comprehensive list of fishes in the Limoncocha Biological Reserve. Thirty-three species belonging to 14 families distributed in 7 orders were collected. The most representative orders in number of species and specimens were Characiformes, Siluriformes, and Perciformes, respectively, being Characiformes as the most important in terms of richness and abundance of species. Characidae (Characiformes) exhibited the greatest abundance and broadest distribution in our samples. A short morphological description and morphometric measurements of each species are also presented.

Notes on the distribution of Gastrotheca testudinea (Jiménez de la Espada, 1870) in Ecuador https://checklist.pensoft.net/article/15084/ Check List 13(4): 121-125

DOI: 10.15560/13.4.121

Authors: Verónica L Urgilés, Juan Carlos Sanchez-Nivicela, Diego F Cisneros-Heredia

Abstract: We present new information on the distribution of the marsupial frog Gastrotheca testudinea (Jiménez de la Espada, 1870) in Ecuador. We provide the first record from the province of Cañar, and the southernmost locality for Ecuador (which also corresponds to the third known report from the province of Zamora-Chinchipe). In addition, we review the elevation range of the species, and propose to change the lowest elevation limit of G. testudinea from 1100 to 700 m.

Southernmost records of Hyalinobatrachium fleischmanni (Anura: Centrolenidae) https://checklist.pensoft.net/article/14988/ Check List 13(4): 67-70

DOI: 10.15560/13.4.67

Authors: Fernando K Cruz, Veronica L Urgiles, Juan Carlos Sánchez-Nivicela, David C Siddons, Diego Cisneros-Heredia

Abstract: We present new records for Fleischmann’s Glassfrog, Hyalinobatrachium fleischmanni (Boettger, 1893), which extend the distribution of this species into central and southwestern Ecuador and thus represent the southernmost known localities. These new reports are based on specimens collected at Cerro de Hayas, province of Guayas, and Macul, province of Los Ríos. These new localities extend the known geographic range of H. fleischmanni by approximately 250 km south of previous known occurrences.

Large and medium-sized mammals of Buenaventura Reserve, southwestern Ecuador https://checklist.pensoft.net/article/14983/ Check List 13(4): 35-45

DOI: 10.15560/13.4.35

Authors: Jeronimo Torres-Porras, Marlon E Cobos, José Manuel Seoane, Nikolay Aguirre

Abstract: Mammals are the third most threatened group of vertebrates and tropical ones are the most endangered according to recent studies. The Buenaventura Reserve protects 20 km2 of Montane Tropical forest in the southwestern part of the Ecuadorian Andes. This study estimates the mammal species richness of this reserve by using camera traps and occasional sightings. We recorded 20 species of large and medium-sized mammals in this small protected area, which shows the reserve’s important role in the conservation of these species. This study also shows the conservation priority that these forests should have in the western part of the Ecuadorian Andes.
