Abstract

Objective: Species inventorying is a fundamental task in biodiversity research and conservation practices, and detailed species catalogue is of great significance for biodiversity research and conservation.

Method: Based on the reptile checklist of Reptilian Fauna of Guizhou, combing with bibliographies on reptile taxonomy in Guizhou Province published in the past 38 years since the publication of the above monograph, the list of reptiles in Guizhou Province has been revised and updated.

Results: As of June 30, 2023, a total of 120 species distributed across two orders, 21 families, and 57 genera were recorded in Guizhou Province. This comprises five species in five genera and three families of Testudines, and 115 species in 52 genera and 18 families of Squamata (including 27 species in 12 genera and six families of Lacertilia, and 88 species in 40 genera and 12 families of Serpentes). The resulting reptilian diversity is the same as Sichuan Province, which are both ranked as fifth in China, with only the Yunnan, Guangxi, Guangdong and Fujian provinces featuring a higher density. For species listed in the Reptilian Fauna of Guizhou, the taxonomy or Chinese common names of 78 taxa were updated or revised accordingly. Furthermore, the provincial records of three species were removed, while 23 species were added to the previous checklist (including five new species and 18 new provincial records of Guizhou). The composition of the reptile fauna in Guizhou Province was mainly composed of the Oriental Realm (105 species), the remaining 15 species are considered to have a widespread distribution, with no species represented from the Palaearctic Realm. Of the recorded diversity, 11 species are listed as Class II nationally protected, 29 species are considered as threatened based on China’s Red List of Vertebrate Animals, 27 species are endemic to China, and the type localities of five species are in Guizhou, including Gekko liboensis, Hemiphyllodactylus dushanensis, H. huishuiensis, Protobothrops maolanensis, and Goniurosaurus liboensis.

Conclusion: This article and its described data can be used for understanding the changes and distributions of reptile species in Guizhou Province, providing basic data support for the protection of reptile resources in Guizhou Province. It is recommended to increase the research on the classification and distribution of reptiles in Guizhou Province, which will further clarify the reptile resources in Guizhou Province.
