Yellow-headed Rock Gecko  
Figs. 23, 24  
 Holotype. THNHM 15909. Type locality: “ Sai Yok National Park, Kanchanaburi Province, Thailand (14°20.09N, 98°51.35E)” at 125 m in elevation.   
 Diagnosis. Maximum SVL 43.5 mm; 7–10 supralabials; 6–9 infralabials; smooth ventral scales; 5–8 contiguous, pore-bearing, precloacal scales with round pores; 18–24 paravertebral tubercles; tubercles on flanks; tubercles in lateral caudal furrows; no ventrolateral caudal tubercles; lateral caudal tubercle row absent; subcaudals smooth, with no enlarged or weakly keeled median scale row; one or two postcloacal tubercles on each side of tail base; no enlarged femoral or subtibial scales; subtibials smooth; no enlarged submetatarsal scales on first toe; 21–31 subdigital fourth toe lamellae; head, forelimbs, tail, gular region, throat, pectoral region, underside of forelimbs, and subcaudal region yellow in males (Tables 6,7).   
 Color pattern (Figs. 23,24). Males: Cnemaspis huaseesom are capable of considerable change in coloration from a light to darker phase. The description that follows is of the darker phase: dorsal ground color of head, forelimbs and tail yellow, with faint banding on tail; dorsal ground color of trunk and hind limbs dark-gray and bearing large, light-gray, paravertebral spots extending from occiput to base of tail; dorsal surface of hind limbs bearing large, light-gray spots; dorsal surface of forelimbs bearing small, yellow markings; top of head mottled; dark postorbital stripes faint; large, round, whitish markings on nape; trunk uniformly gray; tubercles on body lightly colored; belly pale gray; ventral surface of hind limbs gray; fine, dark stippling on all ventral surfaces, most dense on belly. Some adult males may have a gray, as opposed to yellow tail. Females: lack yellow head, forelimbs, and tail, have same general trunk color as males in dark phase; overall ground color of head, body, limbs, and tail light brown; large, lighter, paravertebral markings extend from nape to base of tail where they continue posteriorly to form lightly colored, caudal bands; flanks densely stippled with cream-colored markings and bear faint, gray bars; limbs mottled; all ventral surfaces beige with faint stippling that is most dense on belly and tail.   
 Distribution. Cnemaspis huaseesom is known only from the type locality of Sai Yok National Park, Kanchanaburi Province, Thailand (Fig. 3).   
 Natural history. Grismer et al. (2010a) stated that Cnemaspis huaseesom is most commonly found on hillsides in lowland areas with karst boulders in semideciduous, dipterocarp forest amongst thick vegetation including bamboo. Lizards are generally active at night on karst boulders but may be found on vine-like vegetation near the boulders (Fig. 24). This species is fast, wary, and flees into deep cracks and crevices at the slightest provocation. More than one lizard is usually found on a given outcropping. Lizards are only rarely observed during the day.   
 Relationships. Cnemaspis huaseesom is the sister species of C. siamensis (Fig. 2).
