Abstract

A new species of the kukri snake genus Oligodon H. Boie in Fitzinger, 1826 is described based on two specimens collected from Shangxi Nature Reserve, Hainan Island, China. Oligodon bivirgatus sp. nov. can be distinguished from its congeners by a unique combination of having 15/15/15 dorsal scale rows, eight maxillary teeth, divided nasal, 3 temporals (1+2), 7 supralabials and 7 infralabials; divided anal plate; reddish-brown dorsum with two distinct dark stripes, and reddish ventral surface (in life) with irregular dark blotches on edge cream. This is the first new Oligodon species described from a type-locality in Hainan Island of China.
