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.

Keywords: Cyrtodactylus saiyok sp. nov., new species, taxonomy, limestone



Etymology. The specific epithet saiyok refers to the name of the district in which the type locality is situated. It is a noun in apposition, invariable. We suggest the following common names: Took-kai Sai Yok (Thai), Sai Yok bent-toed gecko (English), Cyrtodactyle de Saï Yok (French), Saiyok Bogenfingergecko (German), Saiyokkromvingergekko (Dutch). The common name Sai Yok Bent-toed Gecko had been proposed by Ellis and Pauwels (2012) for Cyrtodactylus tigroides, for which we here propose the new common name Tiger Bent-toed Gecko.
