摘要This study provides an updated checklist of snake species in China,building upon the 2020 checklist and incorporating comprehensive review of relevant literature published from 2020 to December 2024,as well as pre-2020 sources that may have been overlooked.As of the end of 2024,the Chinese Serpents fauna included 19 families,71 genera,and 355 species of snakes.Significant progress has been made in the past five years,including the description of one new family,one new genus,and 60 new species.One subfamily and seven subspecies were elevated to full status,and 12 species were resurrected as valid species.Four genera and 27 species were newly recorded,three genera and four species were synonymized,and one family,four genera,and 12 species were excluded from the documented herpetofauna.This updated list highlights the presence of significant snake diversity and unresolved taxonomic challenges,emphasizing the potential for further discoveries.It also identifies under-researched groups,stressing the urgent need for focused taxonomic and ecological efforts to enhance our understanding of snake biodiversity in China.
