  "abstract": "Background: Vietnam is home to 19 species of wolf snakes, genus Lycodon. Over the last five years, six new species have been discovered in the country.\n\nNew information: Lycodon yunnanensis (Werner) is reported for the first time from Ha Tinh Province, Vietnam. Genetic analysis of the mitochondrial cytochrome b (cytb) and cytochrome c oxidase subunit I (COI) fragments shows that their genetic distances are below 1.65% and 2.89%, respectively. In addition, new records of Lycodon truongi Nguyen, Duong, Wood & Grismer are reported from central Vietnam, based on eight specimens collected in Da Nang City and Quang Ngai Province. Although the newly-collected specimens exhibit some morphological variations from the holotype specimen, the genetic divergence between samples from the populations is estimated to be less than 2.0%, based on a fragment of cytb.",
