摘要：Situated in the topographically complex transition between the Neotropics and the temperate biomes of North America,
the state of Sonora, Mexico, has an extraordinarily diverse herpetofauna. Surprisingly little research has been conducted
on the state’s amphibians and reptiles and many systematic and biogeographic questions remain unanswered. To
facilitate future research, we provide a checklist of Sonora’s herpetofauna, documenting species presence based on
museum specimens, our fieldwork, and published research. Sonora’s herpetofauna is placed in a regional biogeographic
perspective via a checklist for the six adjoining states together with faunal analyses. A total of 402 species of
amphibians and reptiles are recorded from these seven states. Sonora has the greatest species richness (187 species),
followed by Chihuahua (169 species), and Sinaloa (146 species). Sonora's herpetofauna is most similar to that of
Chihuahua, with which it shares a long border. Eleven biogeographic affinity-based faunal groups are recognized. Of
these, three are dominant in Sonora: a core group classified as "Sonoran" demonstrates strong affinity to Sonoran
Desertscrub and Sinaloan Thornscrub communities; a Tropical group - with many species reaching their northern
distributional limits in the state; and a Madrean group consisting largely of montane species. Our state-level faunal
analysis provides some evidence of peninsular depauperization of the herpetofauna on the Baja California peninsula due
in part to the small number of Neotropical species present in Baja California Sur. Our faunal analysis points toward
distinctive mainland and peninsular Sonoran Desert herpetofaunas centered on Sonora and the Baja California
Peninsula, respectively, each with about 50 non-insular species, and each with species-level endemism nearing 50%.
