Taxonomic status of Lycodon subcinctus sensu lato in China (Serpentes, Colubridae)

The Malayan Banded Wolf Snake Lycodon subcinctus Boie, 1827 once included three subspecies, namely L. s. subcinctus Boie, 1827, L. s. sealei Leviton, 1955, and L. s. maculatus (Cope, 1985). Thereafter, L. s. sealei has been elevated to species level, and the taxonomic status of L. s. maculatus has not been resolved. We sequenced the mitochondrial cytochrome b (cytb) gene fragments of eight specimens ofL. s. maculatus from China, including three from the adjacent areas of its type locality. Combining the sequences obtained from GenBank, we reconstructed a molecular phylogeny and reevaluated the taxonomic status ofL. s. maculatus. Phyloge-netic analysis revealed three highly divergent lineages within L. subcinctus sensu lato which correspond to L. subcinctus sensu stric -to, L. sealei, and L. s. maculatus, respectively. Coupled with morphological comparison, we elevate L. s. maculatus to full species and redescribe it based on the type and freshly collected material.
