Abstract: From a large-scale sampling of limnoterrestrial tardigrades in the Valley of Mexico Basin, in the Huasteca Potosina, and Monarch Butterfly Sanctuary, Mexico, we develop an initial species list and determine the type of vegetation and substrates for most sampled species. In total 160 moss samples and over 2000 tardigrades were obtained, belonging to 17 genera, 35 putative species, one subspecies, of which eight could be accurately identified to species or subspecies, three to affinity, and 15 as morpho-species; the remaining samples were identified to genus, mainly due to the few specimens available and their preservation was not optimal. We provide novel records for one genus and two species from the country. Our estimates on five vegetation types and three substrate types indicates that our inventory is incomplete, and as many as twice the number of species may still be found in these ecosystems.

First verified record of Mastigodryas melanolomus (Cope, 1868) (Serpentes, Colubridae) from Isla del Coral, Nayarit, Mexico https://checklist.pensoft.net/article/111461/ Check List 20(1): 205-211

DOI: 10.15560/20.1.205

Authors: Eduardo A. Gómez-Hernández, Armando H. Escobedo-Galván

Abstract: The occurrence of the Salmon-bellied Racer, Mastigodryas melanolomus (Cope, 1868), on the Isla del Coral in the Pacific coast of Mexico is confirmed through the examination of squamation and the use of other morphological characters. Additionally, we conducted a morphological analysis to assess the differences between M. melanolomus and Masticophis lineatus (Bocourt, 1890), which was previously reported on the island. The results of our analysis suggest a possible misidentification of the previous record. Further investigations and explorations will yield additional insights about whether both species occur on Isla del Coral.

The nematode tapeworm: rediscovery of the bizarre parasite of nematodes, Spirogyromyces vermicola Tzean & Barron (Fungi, incertae sedis) in northeastern Mexico https://checklist.pensoft.net/article/111060/ Check List 19(6): 869-875

DOI: 10.15560/19.6.869

Authors: Martha Santis-Santis, Moisés Felipe-Victoriano, Sergio R. Sanchez-Peña

Abstract: We report the second world observation of the bizarre nematode-parasitic fungus-like organism, Spirogyromyces vermicola, from forest soil at Saltillo, Mexico. It is a benign parasite of nematodes that fills their intestine. Its phylogenetic position remains a mystery, but its morphology and development are reminiscent of Harpellales and Orphellales in the Kickxellomycotina. Spirogyromyces was cultivated in vivo in the original host (Rhabditis) and in Caenorhabditis elegans. Spirogyromyces proliferated in both hosts, and it did not appear to affect significantly health, reproduction, or numbers of hosts. The rediscovery of Spirogyromyces will highlight its potential in the study of parasitic systems in nematodes, including Caenorhabditis research.

First records of Lepidophyma zongolicum García-Vázquez, Canseco-Márquez & Aguilar-López, 2010 (Squamata, Xantusiidae) from Veracruz, Mexico https://checklist.pensoft.net/article/106996/ Check List 19(5): 635-638

DOI: 10.15560/19.5.635

Authors: Angel I. Contreras-Calvario, Medardo Arreortúa, Adán Bautista-del Moral, Jorge L. Castillo-Juárez, Rene Avalos-Vela

Abstract: Lepidophyma Duméril, 1851 is the most diverse genus among the nocturnal lizards, with 23 species distributed from the Atlantic and Pacific slopes of Mexico southeast into Panama. Currently, the available information on the ecology and distribution of these species is limited mainly due to their saxicolous habits. Here we present five new state records of Lepidophyma zongolicum from Atoyac, a locality in the state of Veracruz, Mexico. These new data expand the geographic range of this species by 48 km from its nearest previously known occurrence.

New data on the distribution and echolocation calls of Big Naked-backed Bat, Pteronotus gymnonotus (Wagner, 1843) (Chiroptera, Mormoopidae): northernmost records in Mexico https://checklist.pensoft.net/article/106621/ Check List 19(4): 521-526

DOI: 10.15560/19.4.521

Authors: Karla P. Borges-Jesús, Antonio Guillén-Servent, Vinicio J. Sosa

Abstract: Pteronotus gymnonotus (Wagner, 1843) has its northernmost distribution records in southeastern Mexico, where it is classified as an endangered species. In this report we communicate two northernmost extralimital acoustic records of the species in the state of Veracruz, obtained in 2018 and 2022. The average constant frequency of echolocation calls of P. gymnonotus was 56.5 kHz in Boca Andrea and 53.88 kHz in Buena Vista. Acoustic detection surveys of the conspicuous echolocation calls of the species would help much in the detection of the species in roosts and foraging habitats.

Annotated checklist of amphibians and reptiles from Querétaro, Mexico, including new records, and comments on controversial species https://checklist.pensoft.net/article/98675/ Check List 19(2): 269-292

DOI: 10.15560/19.2.269

Authors: Mauricio Tepos-Ramírez, Fátima Soledad Garduño-Fonseca, Cristhian Alejandro Peralta-Robles, Oscar Ricardo García-Rubio, Ricardo Cervantes Jiménez

Abstract: We present an updated checklist of amphibians and reptiles of Querétaro, Mexico. The herpetofauna of Querétaro is composed of 136 species, 35 amphibians (seven caudates and 28 anurans) grouped in nine families and 20 genera; 101 reptiles (five turtles, 33 lizards, and 63 snakes) grouped in 20 families and 59 genera. We did not include 13 previous records that do not have adequate evidence. We include three newly reported species for Querétaro: Coniophanes imperialis (Baird & Girard, 1859), Scaphiodontophis annulatus (Duméril, Bibron & Duméril, 1854), and Xenosaurus newmanorum (Taylor, 1949). A total of 69 species (51% of the total species) are endemic to Mexico, while one species, Sceloporus exsul (Dixon, Ketchersid & Lieb, 1972), is endemic to the state. According to Mexican law (SEMARNAT NOM-059), 50 species are threatened or under special protection, while according to the IUCN red list, only 11 species are under some category of risk. We suggest that a greater survey effort for amphibians and reptiles is required to discover unrecorded species in those areas that have not been sufficiently sampled.

Confirmation of the presence of the Striped Lizard Eater, Mastigodryas dorsalis (Bocourt, 1890) (Squamata, Colubridae), in Mexico https://checklist.pensoft.net/article/89891/ Check List 19(1): 115-125

DOI: 10.15560/19.1.115

Authors: Jorge Arturo Hidalgo-García, Roberto Luna-Reyes, Adam G. Clause, Rubén Alonso Carbajal-Márquez, José Jesús Sigala-Rodríguez, Luis Antonio Muñoz-Alonso

Abstract: The snake Mastigodryas dorsalis (Bocourt, 1890) is generally considered absent from Mexico, but a few sources indicate otherwise. Herein we resolve this issue by re-examining a historical specimen and by reporting new records for M. dorsalis in Chiapas, Mexico. These records extend the known distribution of the species 87 km northwest of the nearest pre-existing record in Guatemala. Additionally, based on these new records and an exhaustive literature review, we present an updated distribution for the species and revise its known elevational range to 300–2110 m. A complete Spanish translation of this paper is available in the Supplemental Data. Una traducción completa al español de este artículo está disponible en los Datos Suplementarios.

The holoplanktonic mollusks (Pteropoda and Pterotrachoidea) in surface waters of the Campeche Canyon (southern Gulf of Mexico) during a winter storm (“Nortes”) season https://checklist.pensoft.net/article/86711/ Check List 18(6): 1321-1331

DOI: 10.15560/18.6.1321

Authors: Zayra López-Cabello, Erik Coria-Monter, María Adela Monreal-Gómez, David Alberto Salas-de-León, Elizabeth Durán-Campos, Adolfo Gracia

Abstract: The holoplanktonic mollusks (Mollusca, Pteropoda and Pterotrachoidea) are independent and key groups of organisms in any marine ecosystem due to the role they play in the carbon and energy transfer along the marine trophic webs. We document the species of holoplanktonic mollusks collected in the surface waters (10 m depth) during an oceanographic expedition in the Campeche Canyon, southern Gulf of Mexico, during the February 2011 winter storm (“Nortes”) season. Organisms were collected using a close/open/close net system. Eighteen species belonging to 12 genera and nine families of pteropods were identified. Three species of Pterotrachoidea were identified. Limacina trochiformis (d’Orbigny, 1835), Heliconoides inflatus (d’Orbigny, 1835), and Creseis conica (Eschscholtz, 1829) were the species with highest density values (600.3, 678.5, and 746.8 ind · 100 m−3, respectively). The results presented here contribute to the knowledge of this group of organisms in oceanic waters of the southern Gulf of Mexico, especially during a time of year where observations are scarce.

Distribution of Phloeosinus tacubayae Hopkins, 1905 (Curculionidae, Scolytinae), the Cypress Bark Beetle, and new records from potential distribution models https://checklist.pensoft.net/article/87561/ Check List 18(5): 1165-1175

DOI: 10.15560/18.5.1165

Authors: Montserrat Cervantes-Espinoza, Gerardo Cuellar-Rodríguez, Enrico Alejandro Ruíz, Thomas H. Atkinson, José Francisco García Ochaeta, Juan Alfredo Hernández-García, Francisco Armendáriz-Toledano

Abstract: We evaluated the biotic and abiotic conditions related to the presence of Phloeosinus tacubayae Hopkins, 1905, to update its distribution and explore new areas to collect the species from potential distribution models and establish its host range. Our results support that P. tacubayae is an oligophagous species distributed mostly in five provinces from the Mexican Transition Zone; its distribution pattern belongs to the Nearctic cenocron and is related to the distribution pattern of its principal host. The modeling and distribution of its hosts suggest invadable zones where new records may exist.

First record of Tantilla flavilineata Smith & Burger, 1950 (Squamata, Colubridae) for Puebla, Mexico https://checklist.pensoft.net/article/90965/ Check List 18(5): 979-982

DOI: 10.15560/18.5.979

Authors: Angel I. Contreras-Calvario, Rene Avalos-Vela, César Orozco, Víctor H. Jiménez-Arcos

Abstract: We record Tantilla flavilineata Smith & Burger, 1950, for the first time in the state of Puebla, Mexico. It was previously considered endemic to a small region of the state of Oaxaca. With this record, we extend the known distribution 100 km north-northwestward in a straight line. We also provide scales counts and description of the coloration in life of a female specimen. The geographic distribution of T. flavilineata appears to be restricted to mid-elevations in various oak woodlands which have been limited in area by agriculture. More information on its natural history, ecology, and geographic distribution is needed to develop conservation strategies for this rare snake.

An updated checklist of the herpetofauna from Isla María Cleofas, Mexico https://checklist.pensoft.net/article/76773/ Check List 18(1): 241-252

DOI: 10.15560/18.1.241

Authors: Jose Rafael Nolasco-Luna, Ilse K. Barraza-Soltero, Manuel A. López-Montes, Jesús A. Moreno-López, Armando H. Escobedo-Galván

Abstract: We provide an updated checklist of amphibians and reptiles from Isla María Cleofas, Mexico. This island is located at the Islas Marías Archipelago Biosphere Reserve on the coast of the state of Nayarit. The herpetofaunal diversity of Isla María Cleofas has been addressed for over a century; however, the literature is limited just a few scientific explorations and occasional records. In addition, previous herpetofaunal lists contain taxonomic inaccuracies, which are revised here, and recent nomenclatural changes are incorporated. Records of three newly reported species, Lampropeltis polyzona Cope, 1860, Leptophis diplotropis (Günther, 1872) and Tantilla calamarina Cope, 1866, were obtained during our fieldwork. Based on both our field observations and a literature review, the herpetofauna of Isla María Cleofas includes 16 species (two amphibians and 14 reptiles). We also review the conservation status of all species using three independent systems [NOM 059-SEMARNAT-2010, IUCN, and environmental vulnerability score (EVS)]. Finally, we discuss the likely occurrence of evolutionary independent lineages on the island.

New records of fungal pathogens of invertebrates from endemic pine forests in Mexico https://checklist.pensoft.net/article/73111/ Check List 18(1): 67-77

DOI: 10.15560/18.1.67

Authors: Rebeca Casique-Valdés, Sten Anslan, Fernando Galindo-García, Sergio R. Sanchez-Peña

Abstract: We report fungal pathogens of invertebrates (FPI) (Entomophthorales, Hypocreales, and Orbiliales) from roots of an endemic Mexican pine, Pinus greggii Engelm. ex Parl., at four primary montane forests using next-generation sequencing. We found twenty-nine OTUs from 18 genera of FPI associated to the roots of P. greggii. New records for Mexico are: Beauveria felina (DC.) J.W.Carmich., Dactylella mammillata S.M. Dixon, Dactylella ramosa Matsushima, Drechslerella brochopaga (Drechsler) M. Scholler, Hagedorn & A. Rubner, Hirsutella minnesotensis Chen, Liu & Chen, Leptobacillium leptobactrum (W.Gams) Zare & W.Gams, Metapochonia variabilis Z.F.Zhang, F.Liu & L.Cai, Monacrosporium leptosporum (Drechsler) A. Rubner, and Simplicillium aogashimaense Nonaka, Kaifuchi & Masuma. A largely unknown array of fungal pathogens of invertebrates are likely to be found in Mexican forests. This work facilitates future analyses of fungal diversity in these primary forests, as well as basic and applied research in biological control.

A new locality for the rare Guerreran Centipede Snake, Tantilla coronadoi Hartweg, 1944 (Squamata, Colubridae), with comments on morphological variation https://checklist.pensoft.net/article/73773/ Check List 17(6): 1745-1749

DOI: 10.15560/17.6.1745

Authors: Ricardo Palacios Aguilar, Samuel A. Santa Cruz Padilla, Víctor H. Jiménez Arcos

Abstract: We record the third known specimen of Tantilla coronadoi Hartweg, 1944 from Guerrero, Mexico. Our new record extends this species’ distribution by 90 km and to a new Mexican biogeographic province (Balsas Basin). The morphological similarity between this and the two previously known specimens supports the validity of the taxon, and otherwise points to the possible presence of an undescribed taxon on the coast of Guerrero. Additional fieldwork yielding a larger series of this and other infrequently encountered species may enable a better understanding of their distribution, natural history, ecology, and conservation.

Distribution extension and first verified records for Narrow-bridged Musk Turtle, Claudius angustatus Cope, 1865 (Testudines, Kinosternidae) in the Selva Lacandona, Mexico https://checklist.pensoft.net/article/70244/ Check List 17(6): 1639-1646

DOI: 10.15560/17.6.1639

Authors: Martín de Jesús Cervantes-López, Ricard Arasa-Gisbert, Omar Hernández-Ordóñez, Víctor Arroyo-Rodríguez

Abstract: We document the first verifiable records of Claudius angustatus Cope, 1865 in the Selva Lacandona, Chiapas, Mexico. Three individuals were observed in different types of anthropic land covers. These records are the most recent observations of C. angustatus in the southeastern zone of its range in more than 20 years, thus representing the southernmost known occurrences of this species. With these records we confirm the long-suspected presence of C. angustatus in the region, increasing the number of reptile species in the Selva Lacandona to 91.

Inventory of medium-sized and large mammals in La Encrucijada Biosphere Reserve and Puerto Arista Estuarine System, Chiapas, Mexico https://checklist.pensoft.net/article/63657/ Check List 17(4): 1155-1170

DOI: 10.15560/17.4.1155

Authors: Julio C. Hernandez-Hernandez, Cuauhtémoc Chavez

Abstract: La Encrucijada Biosphere Reserve (REBIEN) and Puerto Arista Estuarine System (SEPA) are natural protected areas and Ramsar sites in Chiapas, Mexico. In this study, we conducted an inventory of medium-sized and large mammals using camera trapping. We recorded 23 species in the REBIEN and 13 species in the SEPA. In addition, 35% of the species recorded in the two sites are at some category of risk of extinction at the national or international level. The most abundant species in the REBIEN were Northern Raccoon (Procyon lotor (Linnaeus, 1758)) and White-Nosed Coati (Nasua narica (Linnaeus, 1766)). In the SEPA, White-tailed Deer (Odocoileus virginianus (Zimmermann, 1780)), Collared Peccary (Dicotyles crassus (Merrian, 1901)), and White-Nosed Coati (Nasua narica). Our results highlight the importance of both study sites in the conservation of medium-sized and large mammals and underline the urgent need to develop conservation strategies for these areas.

Red Octopus, Octopus rubescens Berry, 1953 (Cephalopoda: Octopodidae), in the Mexican tropical Pacific https://checklist.pensoft.net/article/66844/ Check List 17(4): 1107-1112

DOI: 10.15560/17.4.1107

Authors: María del Carmen Alejo-Plata, Miguel A. Del Río-Portilla, Oscar Illescas-Espinosa, Omar Valencia-Méndez

Abstract: “Octopus” rubescens Berry, 1953 is an octopus of temperate waters of the western coast of North America. This paper presents the first record of “O.” rubescens from the tropical Mexican Pacific. Twelve octopuses were studied; 10 were collected in tide pools from five localities and two mature males were caught by fishermen in Oaxaca. We used morphometric characters and anatomical features of the digestive tract to identify the species. The five localities along the Mexican Pacific coast provide solid evidence that populations of this species have become established in tropical waters.

Medium-sized and large mammals of the pine-oak forests and grasslands of the Rancho Experimental Teseachi in Chihuahua, Mexico https://checklist.pensoft.net/article/61694/ Check List 17(2): 669-681

DOI: 10.15560/17.2.669

Authors: Fernando Álvarez-Córdova, Jesús A. Fernández

Abstract: We document the taxonomic diversity of medium-sized and large mammals present in Rancho Experimental Teseachi, a teaching and research facility of the Universidad Autónoma de Chihuahua located in the northwestern part of Chihuahua, Mexico. Monthly samplings were made with lineal transects of 5 km in two habitats, open grassland and pine-oak forest, where camera-traps and scent-stations were placed, and tracks were searched. Sixteen species of medium-sized and large mammals were recorded in the area, representing 12.03% of the state’s diversity. The greatest diversity was found in the pine-oak forest. Implementing three different sampling techniques at the same time allows the documentation of mammal diversity more efficiently than using only one or two sampling techniques.

Abstract: The Big Crested Mastiff Bat, Promops centralis (Thomas, 1915), is widely distributed from Mexico to South America but has yet to be reported in the state of Sinaloa, Mexico. We collected 122 acoustic recordings of P. centralis from tropical dry forest and agroecosystems in Sinaloa and Sonora for two years (2015 and 2016). We documented a new record for P. centralis outside the known distribution area in northwestern Mexico. Our results reveal that the current P. centralis distribution needs to be reevaluated.

Abstract: Two new orchid records are reported for Hidalgo, Notylia barkeri Lindl. and Trichocentrum cosymbephorum (C. Morren) R. Jiménez & Carnevali. The genus Notylia is reported for the first time, and the list of orchid flora is updated to include 110 taxa. Unexpectedly, the species were recorded in abandoned orange plantations rather than natural vegetation, likely because of the high anthropogenic pressure exerted on their natural populations. These new records highlight the importance of continuing to survey regions such as Hidalgo with scarce orchid records, including both natural and modified vegetation.

First record of Plantago heterophylla Nutt. (Plantaginaceae) for the Brazilian flora https://checklist.pensoft.net/article/29301/ Check List 15(1): 13-16

DOI: 10.15560/15.1.13

Authors: William Matzenauer, Mateus Negrini, Ubiratã S. Jacobi, Sonia M. Hefler

Abstract: We present the first record of Plantago heterophylla Nutt. (Plantaginaceae) to Brazil, based on specimens from Rio Grande, Rio Grande do Sul, Brazil. The species is easily recognized due to its linear leaves, 2 stamens, and pixidium with 10­–30 seeds. Plantago heterophylla is considered native from United States and Mexico, but it is distributed as adventitious in the east of Argentina, Paraguay, and Uruguay. Images from the species and a distribution map illustrating its occurrence in the American continent are provided.

First record of Calliactis tricolor (Le Sueur, 1817) (Cnidaria, Actiniaria, Hormathiidae) in the Veracruz reef system, southwestern Gulf of Mexico https://checklist.pensoft.net/article/24321/ Check List 14(4): 619-631

DOI: 10.15560/14.3.619

Authors: José Luis Tello-Musi, Ricardo González-Muñoz, Fabián H. Acuña, Nuno Simões

Abstract: The sea anemone Calliactis tricolor (Le Sueur, 1817) is an ecologically important member of the benthic community in coastal and coral reefs of the tropical Atlantic, particularly for their propensity to establish mutualistic symbiotic relationships with hermit crabs. This species is presumably distributed throughout the Gulf of Mexico; however, it had never been recorded in the southwestern part of the Gulf. Here we document the first record of C. tricolor in 2 coral reef localities of the Veracruz reef system, Mexico, and update the number of species of sea anemones known for the region.

First record of the invasive coral Oculina patagonica de Angelis, 1908 (Cnidaria, Scleractinia) in the Gulf of Mexico https://checklist.pensoft.net/article/28662/ Check List 14(4): 613-617

DOI: 10.15560/14.4.613

Authors: Norberto A. Colín García, Jorge E. Campos, José L. Tello Musi, Horacio Perez-España, Xavier Chiappa Carrara

Abstract: Colonies of coral with morphology similar to that of Oculina patagonica de Angelis, 1908 were found in the National Park Veracruz Reef System (NPVRS) along the coast of Veracruz, Mexico in the southern Gulf of Mexico. The identity of these colonies as O. patagonica was confirmed by morphological and molecular analyses. Here, we document the first records of O. patagonica in the Gulf of Mexico. This species is native to the Mediterranean Sea, and could have been accidentally introduced to the Gulf of Mexico through ballast water from ships. In the NPVRS, poor environmental conditions such as polluted waters with high sedimentation, and the capability of O. patagonica to adapt could have facilitated the establishment of this species in the Gulf.

Updated checklist of estuarine caridean shrimps (Decapoda: Caridea) from the southern region of Laguna Madre, Tamaulipas, Mexico, with new records and a key for taxonomic identification https://checklist.pensoft.net/article/24600/ Check List 14(2): 479-494

DOI: 10.15560/14.2.479

Authors: Hiram Herrera-Barquín, Antonio Leija-Tristán, Susana Favela-Lara

Abstract: We provide an updated list of the caridean shrimp species from the southern region of the Laguna Madre, Tamaulipas, Mexico, along with a key for taxonomic identification. The survey was conducted in 3 sites during 3 temporal seasons. A total of 2,989 specimens were collected belonging to 12 species, 6 genera, and to the following 4 families: Alpheidae, Hippolytidae, Palaemonidae, and Processidae. Hippolytidae was the most abundant family, followed by Palaemonidae, Alpheidae, and Processidae. The hippolytid Hippolyte obliquimanus Dana, 1852, the palaemonids Palaemon floridanus Chace, 1942, and P. northropi (Rankin, 1898), and the alpheid Alpheus cf. packardii Kingsley, 1880 represent new records for the Laguna Madre and selected areas of the Gulf of Mexico.

New occurrences of Holospira (Bostrichocentrum) goldmani Bartsch, 1906 (Gastropoda, Urocoptidae) in northwestern Oaxaca, southern Mexico https://checklist.pensoft.net/article/23519/ Check List 14(1): 107-112

DOI: 10.15560/14.1.107

Authors: Rosalía Guerrero-Arenas, Eduardo Jiménez-Hidalgo, Celestino Sandoval-García

Abstract: Holospira (Bostrichocentrum) goldmani Bartsch, 1906 is an urocoptid gastropod distributed throughout northwestern Oaxaca in southern Mexico. Since its original description, posterior records have been restricted to the Mixteca Baja region of Oaxaca. The purpose of this paper is to expand on the geographical distribution of this species, georeferencing six additional localities. Five of our sites are located in the Mixteca Alta region of Oaxaca. Holospira goldmani can survive in soil derived from non-calcareous rocks. Field observations of ecological preferences of H. goldmani suggest that they are more ecologically tolerant than previously thought.

New state record and range extension of the Big Crested Mastiff Bat, Promops centralis Thomas, 1915 (Chiroptera, Molossidae), in Veracruz, Mexico https://checklist.pensoft.net/article/21923/ Check List 13(6): 727-731

DOI: 10.15560/13.6.727

Authors: Christian Tomás Alavez Tadeo, Alvar González Christen, Nallely Verónica Rodríguez Santiago

Abstract: The diversity of bats in the Mexican state of Veracruz is high, comprising 89 species. Many of these species deserve special attention because either they remain underrepresented in collections, or they are known from fewer than 5 localities. We confirm the presence of the Big Crested Mastiff Bat (Promops centralis) in Veracruz, and provide additional occurrence records that extend the known geographic distribution of this species by 216 km to the north from previously known sites. Our new record represents the northernmost record of the species on the coastal plain of the Gulf of Mexico. Our findings highlight the presence of gaps in past surveys of mammalian diversity in Veracruz.

Inventory of medium-sized and large mammals in the wetlands of Laguna de Terminos and Pantanos de Centla, Mexico https://checklist.pensoft.net/article/21922/ Check List 13(6): 711-726

DOI: 10.15560/13.6.711

Authors: Mircea G. Hidalgo-Mihart, Fernando M. Contreras-Moreno, Alejandro Jesús-de la Cruz, Rugieri Juárez-López, Yaribeth Bravata de la Cruz, Luz A. Pérez-Solano, Carolina Hernández-Lara, Diana Friedeberg, Dan Thornton, Juan M. Koller-González

Abstract: Wetlands are one of the most productive ecosystems in the world. However, they have received little attention in the tropics. Biodiversity data from the Terminos-Centla wetlands is limited despite the conservation efforts to protect these wetlands. In this study we list the medium-szied and large mammals from 8 sites within the Terminos-Centla wetlands. We recorded 30 native and 1 introduced species, representing 9 orders, 14 families, and 27 genera. Four of the recorded species are Threatened, 9 Endangered, and 1 under special protection under Mexican legislation. Compared with other sites of southeastern Mexico, the area of the Terminos-Centla wetlands has a many more species. Our results highlight the Terminos-Centla wetlands as one of the most important systems of Mesoamerica for the medium-sized and large mammals and and underlines the urgent need to develop conservation strategies for the area.
