We provide the first country record of Opisthotropis durandi Teynié, Lottier, David, Nguyen & Vogel, 2014 from Vietnam based on a single snake specimen from Dien Bien Province. The species previously was only known from the Lao People’s Democratic Republic (Laos). DNA sequence data of a male specimen from Vietnam match those of a specimen of O. durandi from Phongsali province, Laos, and the newly collected individual from Vietnam also corresponds to O. durandi in terms of diagnostic morphological features, except for a slightly higher ventral number (185 versus 177−181). |
