Article Synopsis
- - Systematic assessments of species extinction risk are crucial for effective conservation, and the second Global Amphibian Assessment evaluated over 8,000 species for their threat levels.
- - Amphibians are the most at-risk vertebrates, with 40.7% of species globally threatened, and their status has worsened since previous assessments, especially in salamanders and the Neotropics.
- - The major threats contributing to declining amphibian populations include disease, habitat loss, and increasing impacts from climate change, highlighting the urgent need for more conservation funding and initiatives to reverse negative trends.
The Selva Zoque region is characterized by a great variety of ecosystems for which there is little information about reptile species diversity and their conservation status. This study is the first assessment of the species richness, composition, and conservation status of reptiles of this region. Additionally, this information is compared with that of seven other tropical regions in northern Mesoamerica.

- A new species from the Geophis dubius group has been identified in the Sierra Zongolica and Sierra de Quimixtlán mountains of Mexico.
- This new species shares similarities with Geophis duellmani and Geophis turbidus but can be differentiated by specific scale patterns and its bicolor appearance.
- With the addition of this new species, the total number of species in the genus Geophis increases to 50, including 12 in the Geophis dubius group, along with a key for species identification.
