Abstract
A new species of Parachute Gecko, Ptychozoon kaengkrachanense sp. nov., is described from montane evergreen forest in Kaeng Krachan National Park, western Thailand. It differs from all known Ptychozoon species by having three dark dorsal chevrons between limbs insertions, homogeneous dorsal scalation without enlarged scales, original tail without long terminal flap, supranasals widely in contact, a continuous series of 14–19 enlarged precloacofemoral scales, bearing 13–17 pores in males, the absence of a predigital notch in the preantebrachial cutaneous expansion and the presence of cutaneous expansions on sides of head. It is the eighth species described in the genus and the only species of Ptychozoon endemic to Thailand.

Key words: Thailand, Phetchaburi Province, Kaeng Krachan National Park, Ptychozoon kaengkrachanense, new species, taxonomy

Seven species of parachute geckos of the genus Ptychozoon are known, there is now an eighth species Ptychozoon kaengkrachanense a Thailand endemic which inhabits montane evergreen forest in Kaeng Krachan National Park, in western Thailand. The new species differs from all known Ptychozoon species by having three dark dorsal chevrons between limbs insertions, homogeneous dorsal scalation without enlarged scales, original tail without long terminal flap, supranasals widely in contact, a continuous series of 14–19 enlarged precloacofemoral scales, bearing 13–17 pores in males, the absence of a predigital notch in the preantebrachial cutaneous expansion and the presence of cutaneous expansions on sides of head.

Ptychozoon kaengkrachanense is the fifth species of Ptychozoon recorded from Thailand, along with PhorsfieldiiPkuhliPlionotum and Ptrinotaterra. and it is the only Ptychozoon species endemic to Thailand. It is the 68th reptile species recorded from Kaeng Krachan National Park, which was already known to house the richest herpetofauna of all protected areas of Thailand and it thus reinforces the exceptional value of the park in terms of biodiversity and its conservation.
