title: Cyrtodactylus saiyok sp. nov., a new dry evergreen forest-dwelling Bent-toed Gecko (Squamata: Gekkonidae) from Kanchanaburi Province, western Thailand.
abstract: We describe Cyrtodactylus saiyok sp. nov. from a dry evergreen forest on a limestone hill in Khao Krajae, Sai Yok District, Kanchanaburi Province, western Thailand. It is characterized by a maximal known SVL of 61.0 mm; 18-19 longitudinal rows of dorsal tubercles; 23 or 24 ventral scale rows between ventrolateral skin folds; a continuous series of enlarged femoro-precloacal scales, including 5 pore-bearing precloacal scales (males); no precloacal groove or depression; transversely enlarged subcaudal scales; a complete black nuchal loop; a W-shaped band above shoulders and 3-5 irregular, medially interrupted or not, black dorsal bands between limb insertions. Cyrtodactylus saiyok sp. nov. is the sixth reptile species that is possibly endemic to Sai Yok District.
