Abstract

Achalinus pingbianensis Li, Yu, Wu, Liao, Tang, Liu et Guo, 2020, a species previously known only from a male collected in Yunnan Province (People’s Republic of China), is reported for the first time from Vietnam (Lao Cai Province) based on the re-examination of nine specimens deposited in the collections of the Muséum National d’Histoire Naturelle which were formerly identified as Achalinus spinalis. Furthermore, we also provide the first description of a female specimen and an expanded diagnosis of the species. The short discussion of the identification and distribution of Achalinus spinalis and A. rufescens is provided.
