 We describe a new forest-dwelling Cyrtodactylus from Doi Inthanon, Chiang Mai Province, northern Thailand. Cyrtodactylus inthanon sp. nov. is characterized by a maximum known SVL of 87.3 mm; 18 to 20 longitudinal rows of dorsal tubercles; a continuous series of 34 to 37 enlarged femoro-precloacal scales, including four to six pitted (female) or porebearing (male) scales on each femur separated by a diastema from five pitted (females) or pore-bearing (male) precloacal scales; no precloacal groove or depression; transversely enlarged subcaudal scales; and three to five irregular beige dorsal bands between limb insertions. The discovery of a new reptile endemic to Doi Inthanon reinforces the high importance of this mountain in terms of biodiversity conservation.

Distribution and natural history. The species is known only from Doi Inthanon, from 700 to 1010 m a.s.l., where it is common. We encountered it while it was active at night on trees and large rocks along streams. It moved slowly when disturbed by torch light and bit when handled. It was found at direct proximity to the reptiles Acanthosaura lepidogaster (Cuvier) (Agamidae), Gekko gecko (Linnaeus), Hemidactylus frenatus Duméril & Bibron and H. platyurus (Schneider), Hemiphyllodactylus chiangmaiensis Grismer, Wood & Cota (Gekkonidae), Ahaetulla prasina (Boie) (Colubridae), Amphiesma khasiense (Boulenger) (Natricidae) and Trimeresurus popeiorum Smith (Viperidae), and the amphibians Ansonia inthanon Matsui, Nabhitabhata & Panha (Bufonidae), Leptolalax pelodytoides (Boulenger), Megophrys major Boulenger and M. minor Stejneger (Megophryidae), Amolops marmoratus (Blyth), Hylarana nigrovittata (Blyth) and Odorrana livida (Blyth) (Ranidae). Captive specimens ate meal worms and crickets and seemed to quickly dehydrate with decreasing hygrometry. The new species’ known range entirely falls within Doi Inthanon National Park.

Etymology. The specific epithet inthanon refers to the type locality. It is a noun in apposition, invariable. We suggest the following common names: ตุ๊กกายดอยอินทนนท์ 'Took-kai Doi Inthanon' (Thai), Doi Inthanon bent-toed gecko (English), Cyrtodactyle du Doï Inthanon (French), Doi Inthanon Bogenfingergecko (German), Doiinthanonkromvingergekko (Dutch).
