Molecular assessment of pitviper populations (genus Trimeresurus) in Laos and Vietnam reveals new country record and overlooked diversity

Vietnam is home to at least ten species of the genus Trimeresurus (Asian green pitvipers) and at minimum five members are found in Laos. The number has been increasing in recent years because of new species descriptions, e.g., Trimeresurus guoi, and new records of recently discovered taxa, such as T. cardamomensis.
