Three new species of the genus Tropidophorus, characterized by distinct depression of body, strongly keeled lateral body scales, and saxicolous habits, are described from Indochina. Of these, two moderately depressed species, one with undivided frontonasal and widened paravertebral scales, and the other with divided frontonasal and unwidened paravertebral scales, were collected from small areas in northeastern and eastern Thailand, respectively. The remaining species with extremely depressed head and body was found from one limited area in northern Vietnam. The three species most resemble T. baviensis Bourret, 1939 from northern Vietnam among the known congeneric species in body size, body shape, and scutellation. However, body depression in T. baviensis is not so prominent as in the present three species. Considering that most specimens of these species were collected from rock crevices, their characteristic body shapes may represent certain stages of adaptation to life in crevices.
