A new species of Hemiphyllodactylus (Squamata, Gekkonidae) from southwest Yunnan, China.

A new species of gekkonid, Hemiphyllodactylusgengmaensis sp. nov. , is described based on six specimens from Gengma Dai and Wa Autonomous County, Yunnan, China. The new species can be distinguished from its congeners by a significant genetic divergence of greater than 9.7% in the mitochondrial ND2 gene and a combination of the following characters: a maximum SVL of 43.24mm; 8 or 9 chin scales; six circumnasal scales; 2 or 3 internasal scales; 9-11 supralabial scales; 8 or 9 infralabial scales; 11-18 dorsal scales; 8-10 ventral scales; a manual lamellar formula of 5-5-5-4 or 5-6-5-4 and a pedal lamellar formula of 5-5-6-5; 20-25 precloacal and femoral pore-bearing scales contiguous in males; dark postorbital stripes or striping on body; dark dorsal transverse blotches present; and a brown postsacral mark bearing anteriorly projecting arms. The discovery of this new species brings the number of Hemiphyllodactylus species in China to 15.
