摘要Cyrtodactylus geckos are one of the most speciose and diverse groups of extant lizards known,distributed throughout the Asian and Pacific realms.Using molecular phylogenetic methods and supporting morphological data,we describe a new species of Cyrtodactylus in Daweishan National Nature Reserve,Yunnan Province,China.Cyrtodactylus hekouensis sp.nov.can be morphologically distinguished from its nearby congeners by the following characters:maximum SVL 92.3 mm and TL 98.5 mm;11-12 supralabials;11-12 infralabials;36-57 scale rows between the fifth supralabials;10-13 dorsal tubercles rows;3 postnasals on blunt and smooth front snout;precloacal-femoral pores in a continuous series of 33-39 (females with pitted scales) located under vent/cloaca and thighs in both sexes;precloacal groove absent;3/3 postcloacal tubercles;subdigital lamellae under the fourth finger 21 or 22,under the fourth toe 20-23;smooth midbody with smooth venter and tuberculate dorsal scale rows,tubercles from head to tail base;dorsal transverse patterns are generally large,bilaterally symmetrical.The results of the phylogenetic analysis recover specimens of this new species as sister to a clade containing C.wayakonei and C.martini.Uncorrected pairwise intraspecific distances were ＜ 1％,and distances between our new species and other Cyrtodactylus species from nearby countries ranged from 14.2％ to 26.8％.
