A new species of Cyrtodactylus (Squamata, Gekkonidae) from Cambodia's Prey Lang Wildlife Sanctuary

is described from Phnom Chi, an isolated mountain in Prey Lang Wildlife Sanctuary, Kampong Thom Province, Cambodia. The new species is recognized by having a unique combination of morphological characters, including snout-vent length 76.1-80.7 mm; paravertebral tubercles 31-36; ventral scales 45-54; enlarged femoral scales 0-8, without pores; enlarged precloacal scales 7-10, bearing pores 4-5 in males, pits 1-7 in females; the posterior border of nuchal loop unbroken and pointed, bordered anteriorly and posteriorly by a broad yellow or yellowish white band; and yellow spots on top of head. The new species also represents a divergent mitochondrial DNA lineage within the complex that is closely related to , but the phylogenetic relationships among the new species and two divergent mitochondrial subclades within are not resolved based on available sequence data. is the only member of the complex known to occur west of the Mekong River. The new species may be endemic to Phnom Chi, and likely faces imminent conservation threats.
