The growth in our knowledge of the diversity of the herpetofauna of Mexico has occurred over the period of approximately 445 years from the work of Francisco Hernández to that of a broad multinational array of present-day herpetologists. The work of this huge group of people has established Mexico as one of the most significant centers of herpetofaunal biodiversity in the world. This status is the result of a complex orography, in addition to diverse habitats and environments and the biogeographic history of Mexico. The current herpetofauna consists of 1,421 native and introduced species, allocated to 220 genera, and 61 families. This figure is comprised of 1,405 native species and 16 non-native species (as of April 2023). The non-native species include two anurans, 13 squamates, and one turtle. The level of endemism is very high, presently lying at 63%, with this level expected to increase with time. Species richness varies among the 32 federal entities in the country, from a low of 50 in Tlaxcala to a high of 492 in Oaxaca. Amphibian species richness by state-level can be envisioned as comprising three levels of low, medium, and high, with the lowest levels occurring in the Peninsula of Baja California, a group of seven states in north-central and central Mexico, and a group of three states in the Yucatan Peninsula, with the highest levels occupying the southern states of Guerrero, Puebla, Veracruz, Oaxaca, and Chiapas, and the medium level in the remaining states of the country. Reptile species richness also can be allocated to three categories, with the lowest level occupying Baja California Sur, a group of central states, and the states of the Yucatan Peninsula, and the highest level found in a cluster of the states of Veracruz, Guerrero, Oaxaca, and Chiapas. Knowledge of the Mexican herpetofauna will continue to grow with additional studies on systematics, conservation, and the construction of checklists at various levels. [ABSTRACT FROM AUTHOR]

We report the second record of Thamnophis pulchrilatus in the State of Puebla, and the first record of arboreal behavior for the species and second for the genus. In addition, we provide natural history data for this snake species. [ABSTRACT FROM AUTHOR]

Pine-oak clear-cutting in Ixtlán de Juarez, Oaxaca, have been applied for more than 50 years; such forest management modify continuously the structure, arboreal composition, and associated biota. On the other hand, biota survey effort has been insufficient in communal forest areas in Sierra de Juarez, Ixtlán, Oaxaca. Particularly, it is not clear how this forest management affect the occurrence, presence and distribution patterns in reptiles. Our main goal was identifying composition of amphibian and reptiles, comparing distribution, rich- ness and abundance in three areas with different degree of perturbation (agriculture plots, natural forest, and forest management plots). We found that reptile community is composed by 37 species, grouped in 25 genera and 11 families. According to our estimates, we recorded 76% of the extant species in the region and 8. 37% of the extant species in Oaxaca. Within management forest (BMF), constituted by undisturbed (FC) and clear-cutting areas (FA), we identified 15 species: 13 reptiles and two amphibians. We recorded nine species in FC and eight species in FC. In AM we recorded 31 species grouped in 22 genus and 10 families. Biodiversity richness was higher in disturbed areas (AM and FA) than in FC. Although FC and FA are neighboring areas, similarity was higher between AM, with more than 50 years disturbance; and FA, recently disturbed. We also observed interconnectivity among AM, FC and FA areas which can help to maintain the natural amphibian and reptile ensemble. Our results pointed out that distribution and abundance patters are modified during forest clear-cutting process. Further reptile and amphibian inventory in disturbed and natural areas are needed in order to prevent or diminish herptile biota diversity due to continuous forest management. [ABSTRACT FROM AUTHOR]
