A new species of Gekko Laurenti, 1768 (Squamata: Gekkonidae) from Dong Nai Province, Southeastern Vietnam

摘要

A new endemic species of Gekko, G russelltraini, is described from Chua Chan Mountain, an isolated granitic peak in the Xuan Loc district, Dong Nai province, southeastern Vietnam. The species is distinguished from its congeners by its moderate size (SVL 70.3-82.9 mm), 8-11 precloacal pores in males, 12-16 longitudinal rows of very weakly enlarged, smooth dorsal tubercles, 17-18 lamellae beneath digit IV of pes, and dorsal pattern of five to seven white vertebral blotches between nape and sacrum and four to seven pairs of short white bands on flanks between limb insertions. Gekko russelltraini is a member of a group of mid-sized Indochinese Gekko sharing similar habitus, scalation, and color pattern elements and is the seventh member of its genus confirmed for Vietnam.
