Cyrtodactylus dumnuii (Squamata: Gekkonidae), a new cave-dwelling gecko from Chiang Mai Province, Thailand

A new cave-dwelling species of Cyrtodactylus is described from Chiang Mai Province in northern Thailand. Cyrtodactylus dumnuii sp. nov. may be distinguished from all other congeners by the possession of a series of enlarged femoral scales, disjunct precloacal and femoral pores in males (minute precloacal pores variably present in females), a relatively high number (18-22) of closely spaced, regularly arranged dorsal tubercle rows, well-defined non-denticulate ventrolateral folds, transversely enlarged subcaudal plates, and a color pattern of approximately six pairs of alternating light and dark transverse bands on the trunk. It is the nineteenth member of the genus recorded from Thailand and the eighth Thai Cyrtodactylus known to be a facultative troglophile.
