CommentDefinition: A moderately sized Cyrtodactylus, snout-vent length to at least 79 mm; body slender, limbs and digits long, slender; one pair of enlarged postmental scales in broad contact with one another; dorsal scalation with 16-18 rows of keeled tubercles; 36– 38 ventral scales across belly between ventrolateral folds; no precloacal groove, a continuous series of 32–34 pore-bearing precloacal-femoral scales (at least in males). 7–9 broad basal lamellae and 14 narrow distal lamellae beneath 4th toe of pes. Median subcaudal scales enlarged to form broad transverse plates. Dorsal pattern of purplish brown bands, bordered anteriorly and posteriorly by yellowish-cream bands; 3 such bands on trunk and a fourth on nape and occiput (after BAUER et al. 2003).

Diagnosis: Cyrtodactylus chanhomeae may be distinguished from all congeners on the basis of the following combination of characters: body slender, limbs and digits long, dorsal scalation with 16–18 rows of keeled tubercles, 36–38 ventral scales across belly between ventrolateral folds, no precloacal groove, a continuous series of 32–34 pore-bearing precloacal-femoral scales (at least in males), median subcaudal scales enlarged to form broad transverse plates, and dorsal pattern of purplish brown bands, bordered anteriorly and posteriorly by yellowish-cream bands (5 such pale bands between limb insertions). On the basis of its continuous single series of precloacal and femoral pores and absence of a precloacal groove, Cyrtodactylus chanhomeae may be distinguished from C. tigroides and the majority of its other congeners (refer to Diagnosis of C. tigroides). Among those species with a continuous series of pores (or for which this condition could not be adequately assessed based on literature and specimens available to the authors), the new species may be distinguished from the Pacific species C. abrae, C. derongo, C. loriae, C. louisiadensis, C. novaeguineae, and C. tuberculatus on the basis of its much smaller size (to 79 mm SVL for types vs. > 110 mm SVL), as well as lower ventral scale counts and coloration differences. It may be distinguished from C. papilionoides and C. malcolmsmithi by its greatly expanded subcaudal plates, which extend the entire width of the tail, from C. darmandvillei by its much smaller and less coarse dorsal tubercles, from C. jarujini by its lower number of pores (32 vs 52) and banded rather than spotted or blotched pattern, from C. variegatus by its greater number of midventral scale rows (36–38 vs 22), from C. tiomanensis and C. phongnhakebangensis by its greater number of pale bands (4– 5 vs 3) between limb insertions, and from C. feae by its lack of a well-defined reticulate pattern on the dorsum of head. 
EtymologyNamed after Dr. Lawan Chanhome of the Queen Saovabha Memorial Institute of the Thai Red Cross Society, Bangkok. Dr. Chanhome has been and continues to be an active contributor to the study of Thai poissonous snakes.
