A new species of the gekkonid lizard genus Cyrtodactylus Gray, 1827 is described on the basis of material collected in limestone caves at Khao Wong, Rayong Province, Thailand. It is characterized by a slender body, elongate tail and digits, small number (12) of rows of dorsal tubercles, and enlarged patch of precloacal scales bearing only two precloacal pores. The new species is the second tropical Asian Cyrtodactylus believed to be largely associated with cave environments and is the twelfth species of the genus thus far recorded from Thailand.
Key words: Cyrtodactylus sumonthai, sp. nov.; Gekkonidae; description; cave-dwelling
Etymology.– The specific epithet is a partonym honoring Mr. Montri Sumontha of the Ranong Marine Fisheries Station, who collected the type series of the new species.
Distribution and Natural History.– Cyrtodactylus sumonthai is known only from a single mountain, Khao Wong in Rayong Province, southeastern Thailand, which is riddled with limestone caves.
