Abstract
A review of the genus Dopasia Gray, 1853 in the Indochina subregion is provided with the first country record of D. hain-anensis for Vietnam and new distribution records for other species. In addition, we herein confirm the validity of Dopasia ludovici, previously a synonym of D. harti, based on overlooked external morphological differences. According to Uetz (2010), the genus Ophisaurus comprises 12 species grouped in three clades. The New World clade contains five species from North and Central America: Ophisaurus attenuatus Baird, 1880; O. ceroni Hol-man, 1965; O. compressus Cope, 1900; O. mimicus Palmer, 1987; and O. ventralis (Linnaeus, 1766). The Asian clade comprises six species distributed from northern India through the Indochinese peninsula southwards to Indonesia: Ophisaurus buettikoferi Lidth de Jeude, 1905; O. gracilis (Gray, 1845); O. hainanensis Yang, 1983; O. harti Boulenger, 1899; O. sokolovi Darevsky & Nguyen, 1983; and O. wegneri Mertens, 1959.
