Fig. 20 View FIGURE 20

Holotype. UNS 37 View Materials . Type locality: “ Nui Cam Hill , Tinh Bien District, An Giang Province, Vietnam (10°29.7759 N, 105°00.4419 E)” at 100 m in elevation. GoogleMaps

Diagnosis. Maximum SVL 48.2 mm; 7–9 supralabials; six or seven infralabials; smooth ventral scales; 3–6 pore-bearing, precloacal scales separated medially by 1–4 poreless scales; 16–21 paravertebral tubercles; tubercles linearly arranged and present on flanks; caudal tubercles not restricted to a single paravertebral row nor encircling tail; tubercles in lateral caudal furrows occasionally anteriorly; ventrolateral caudal tubercles present anteriorly; lateral caudal tubercle row absent or present only anteriorly; subcaudals smooth and bearing a median row of enlarged scales; 2–4 postcloacal tubercles on each side; no enlarged femoral or subtibial scales; subtibials smooth; no enlarged submetatarsal scales on first toe; 27–33 subdigital fourth toe lamellae; dark, elongate mid-gular marking (Tables 6,7).

Color pattern ( Fig. 20 View FIGURE 20 ). Dorsal ground color dull-yellow, body overlain with large, reddish brown blotches and offset, black, paravertebral blotches; limbs with reddish brown and pale yellow, alternating bands; poorly defined, reddish brown, caudal bands not encircling original tail; top of head and snout with reddish brown reticulum enclosing dull white blotches; scattered, dark spots on top of head; three thin, dark, reddish brown, postorbital stripes infused with black and edged below in white, uppermost not extending onto shoulder region; all ventral surfaces gray, immaculate; gular region bearing a dark, mid-gular line.

Distribution. Cnemaspis nuicamensis is known only from the type locality of Nui Cam Hill 22.5 km south of Chau Doc in Tinh Bien District of An Giang Province, Vietnam near the border of Cambodia ( Fig. 3 View FIGURE 3 ).

Natural history. Nui Cam Hill is part of the Bay Nui Mountains, which are surrounded by the vast, agricultural lowlands of the Mekong Delta flood plain. Nui Cam Hill is the tallest (710 m) in this range of mountains and is dominated by old growth, secondary, semi-deciduous forest and highly disturbed forest. Lizards were all observed during the day on the surface of granite rocks or within rock cracks. Within this microhabitat, Cnemaspis nuicamensis is far more common on vertical surfaces in the vicinity of streams than on rocks within the forest ( Fig. 20 View FIGURE 20 ). Grismer & Ngo (2007) noted that lizards presented tail displays upon escape and no lizards were observed on rocks within disturbed forest.

Relationships. Cnemaspis nuicamensis is the sister species to C. tucdupensis ( Fig. 2 View FIGURE 2 ).
