The Asian Cat Snake genus Boiga Fitzinger, 1826 includes 37 species, with high species diversity. Five species of Boiga have been recorded in China including B. multomaculata (Boie, 1827), B. kraepelini (Stejneger, 1902), B. cyanea (Duméril, Bibron & Duméril, 1854), B. guangxiensis (Wen, 1998) and B. siamensis (Nutaphand, 1971). Previously, the validity of the species Boiga stoliczkae (Wall, 1909) was controversial. B. stoliczkae was considered in synonymy with B. ochracea. Currently, the taxonomy of B. multomaculata and B. ochracea (Theobald, 1868) was revised so that B. multomaculata and B. ochracea actually represent a single species and B. stoliczkae was recognised as a valid species. B. stoliczkae was previously known to be found in the west from central Nepal through Darjeeling, Sikkim and Bhutan to Arunachal Pradesh and Assam in north-eastern India. One adult female specimen of the Asian Cat Snake was collected from Gyirong County, near the China-Nepal border, Tibet, China during fieldwork on August 2023. We compared morphology and mitochondrial DNA sequence data with all the species of the genus Boiga. Both datasets strongly supported referring the Chinese specimens to B. stoliczkae (Wall, 1909) due to the 21 mid-dorsal scale rows and the uncorrected p-distance (mitochondrial DNA gene cytochrome b) between this specimen and B. stoliczkae which is 1.7%. We further described morphological characters of the Chinese specimen in detail and compared these with the specimens that had been previously described. The dorsal ground colour of the Chinese specimen is dark brown, with a black stripe distributed almost evenly across the tail. This is a novel morph of the species B. stoliczkae. The newly-collected Chinese specimen expands the distribution of the species on the Himalaya range.

“…Although useful for species identification, the COI barcoding approach is not suitable for reconstructing higher-level phylogenetic relationships, as suggested by other similar studies (e.g., Hawlitschek et al, 2017;Vences et al, 2005). Currently, there are multiple taxonomic systems for snakes in China (Huang, 2021;Uetz, 2020;Wang, Ren, et al, 2020), with the differences among these taxonomic systems being mainly above the generic level. Our results generally do not resolve phylogenetic relationships above the generic level, and hence cannot be used to resolve higher-level taxonomic controversies on Chinese snakes.…”

“…As one of 17 megadiverse countries (Mittermeier, 1988;www.biodi versi tya-z. org), China harbours an extraordinarily high level of snake species diversity due to a large variety of climatic regions, ecosystems across a vast geographic area, and complex paleoclimatology and palaeogeography (Guo et al, 2016(Guo et al, , 2022Huang, 2021;Wang, Ren, et al, 2020;Zhao, 2006;Zhao & Adler, 1993). At present, 283 species of snakes have been reported from China, representing 8% of the world's snake diversity, and of which at least 60 species are endemic to China (31 December 2020, Chen, Wu, et al, 2021;Uetz, 2020;Wang, Ren, et al, 2020).…”

DNA barcoding has greatly facilitated studies of taxonomy, biodiversity, biological conservation, and ecology. Here, we establish a reliable DNA barcoding library for Chinese snakes, unveiling hidden diversity with implications for taxonomy, and provide a standardized tool for conservation management. Our comprehensive study includes 1638 cytochrome c oxidase subunit I (COI) sequences from Chinese snakes that correspond to 17 families, 65 genera, 228 named species (80.6% of named species) and 36 candidate species. A barcode gap analysis reveals gaps, where all nearest neighbour distances exceed maximum intraspecific distances, in 217 named species and all candidate species. Three species‐delimitation methods (ABGD, sGMYC, and sPTP) recover 320 operational taxonomic units (OTUs), of which 192 OTUs correspond to named and candidate species. Twenty‐eight other named species share OTUs, such as Azemiops feae and A. kharini, Gloydius halys, G. shedaoensis, and G. intermedius, and Bungarus multicinctus and B. candidus, representing inconsistencies most probably caused by imperfect taxonomy, recent and rapid speciation, weak taxonomic signal, introgressive hybridization, and/or inadequate phylogenetic signal. In contrast, 43 species and candidate species assign to two or more OTUs due to having large intraspecific distances. If most OTUs detected in this study reflect valid species, including the 36 candidate species, then 30% more species would exist than are currently recognized. Several OTU divergences associate with known biogeographic barriers, such as the Taiwan Strait. In addition to facilitating future studies, this reliable and relatively comprehensive reference database will play an important role in the future monitoring, conservation, and management of Chinese snakes.
