Checklist of amphibians of Nayarit, western Mexico

Nayarit is one of the Mexican states where less has been published regarding the fauna of amphibians. The aim of this work was to generate a list of amphibians of Nayarit through literature review and fieldwork. The amphibian fauna of Nayarit consists of 37 species, belonging to 21 genera, 10 families, and two orders. Among these 37 species, 36 are native, 21 are endemic to Mexico, and one is exotic (the American bullfrog Lithobates catesbeianus ). In total, nine species are under the category of “Special Protection” and one as “Endangered” by Mexican laws and four (one as “Endangered” and three as “Vulnerable”) under international laws of protection. In the near future, our expectation is that more species will be added to the list of species of amphibians in Nayarit, as more fieldwork remains to be done in some remote and unexplored areas of the state.
