DiagnosisDiagnosis: Cyrtodactylus hinnamnoensis sp. nov. is characterized by: Adult SVL 84.1 ± 11.7 mm (mean ± SD); dorsal head with dark blotches; nuchal loop wide, distinct, posteriorly enlarged; dorsal body with four to six blackish brown bands between limb insertions; 13–19 irregular, weakly keeled dorsal tubercle rows; 35–48 ventral scale rows; ventral scale rows from mental to cloacal slit 179–201; scale rows at midbody 93–112; ventrolateral folds present, without tubercles; 36–44 precloacal-femoral pores in the males; 0–28 pores in females; enlarged femoral and precloacal scales present; 4–6 postcloacal tubercles; subcaudals enlarged.

CommentSexual dimorphism. The females differ from the males by lacking or having fewer precloacal-femoral pores (0–28 versus 36–44 in the males) and the absence of hemipenial swellings at the tail base (see Table 6 in Luu et al. 2016).

Natural history. Specimens were found at night between 19:41 and 22:03h on karst walls, ca. 0.3–5 m above the ground, near cave entrances in the limestone forest, at elevations between 175 and 580 m a.s.l. Only one male specimen VNUF R.2014.99 was collected on a tree trunk, about 1 m from the forest floor. The surrounding habitat was karst forest, dominated by species of Ebenaceae, Dracaenaceae, Arecaeae, Poaceae, Meliaceae, and Moraceae. The relative humidity ranged from 78% to 90%, and temperatures were from 24.9 to 30.7oC (see Table 8). When capturing individuals of the species, we observed an increased rate of tail autotomy and many individuals had regenerated tail, for example, seven of 11 specimens of Cyrtodactylus hinnamnoensis sp. nov. had dropped or/and regenerated tails. This suggests that these populations might be under the stress of predators (see also Grismer et al. 2016). 
EtymologyNamed after its type locality, Hin Nam No NPA where the new Cyrtodactylus species was discovered.
