A snake specimen was collected from a concrete road in Hejiang County (106°16′33″ E, 28°39′06″ N, 696 m above sea level), Luzhou City, Sichuan Province, China, during a survey on the diversity of amphibians and reptiles in June 2023 (Fig. 1). The morphological characteristics of this specimen were similar to those of Longsheng Kukri Snake Oligodon lungshenensis (Fig. 2). On the phylogenetic tree built based on mitochondrial COI gene sequences, the specimen formed a highly supported monophyletic group with Longsheng Kukri Snake (with a Bayesian posterior probability of 0.99) (Fig. 3), and the genetic distance between the two was 1.6% (Appendix 1). The genetic distances between the newly collected specimen and other congeneric species ranged from 3.4% to 16.8%, and those between Oligodon and the outgroup Lycodon gongshan varied between 17.2% and 20.5% (Appendix 1). According to the results from both morphological comparison and phylogenetic analysis, we confirmed that the specimen was O. lungshenensis, representing a new record in Sichuan Province.
