An integrative taxonomic study recognized a new species of the Cyrtodactylus pulchellus group from Kanchanadit District, Surat Thani Province, Southern Thailand. Phylogenetic analyses of the mitochondrial ND2 gene revealed a new species, Cyrtodactylus kanchanaditsp. nov., that is closely related to C. lekaguli. The new species differs from its sister lineage by bearing mean genetic divergence of 4.53% and significant differences in both mensural and morphometric characters (p < 0.05). Cyrtodactylus kanchanaditsp. nov. can be differentiated from the remaining members of the C. pulchellus species group because of its genetic divergence of ≥7.99% and a combination of differences in body size: 11–15 supralabial and 10–12 infralabial scales, 29–35 paravertebral tubercles, 18–23 longitudinal rows of dorsal tubercles, 32–37 rows of ventral scales, 20–23 subdigital lamellae on the fourth toe, 32–37 femoroprecloacal pores in adult males, and four or five dark body bands; weak tuberculation on body; absence of tubercles in the ventral body fold, absence of precloacal pores in females, and absence of scattered pattern of white tubercles on dorsum; presence of precloacal groove depression; and maculated white caudal bands. Cyrtodactylus kanchanaditsp. nov. is currently known from its type locality.
