Abstract: Cnemaspis enneaporus Rujirawan, Aksornneam & Aowphol sp. nov. Figs 4, 5, 6, 7 Type material. Holotype (Figs 4 – 6). ZMKU R 01100, adult male from Thailand, Kanchanaburi Province, Sai Yok District, Wang Khrachae Subdistrict, (14.20247 ° N, 99.02222 ° E; 404 m elevation), collected on 18 November 2022 by Akrachai Aksornneam and Parinya Pawangkhanant. Paratype (Fig. 7). ZMKU R 01101, adult female, same collection data as the holotype. Diagnosis. Cnemaspis enneaporus sp. nov. can be distinguished from all other species in the C. siamensis group by having the unique combination of the following characters: SVL 42.2 mm in adult males (n = 1), 43.7 mm in adult females (n = 1); eight supralabials; seven or eight infralabials; ventral scales smooth; nine continuous precloacal pores in single male specimen; 17 or 18 paravertebral tubercles linearly arranged; tubercles on lower flanks present; lateral caudal furrows present; no caudal tubercles in the lateral furrows; ventrolateral caudal tubercles present on original portion of tail; caudal tubercles not encircling tail; subcaudals smooth; no enlarged median subcaudal row; two postcloacal tubercles on each side of tail; no shield-like subtibial scales; subtibial scales smooth; no enlarged submetatarsal scales; 26–28 subdigital lamellae on the fourth toe; sexually dimorphic for dorsal and ventral colour pattern; prescapular marking absent; gular marking absent; and yellow colouration in life on all ventral surfaces of head, body and tail in adult male. Description of holotype. Adult male; SVL 42.2 mm; head oblong in dorsal profile, moderate in size (HL / SVL 0.29), somewhat narrow (HW / SVL 0.18), flat (HD / HL 0.38), distinct from neck; snout moderate (ES / HL 0.43), snout slightly concave in lateral profile; postnasal region concave medially; scales of rostrum round, smooth, raised, larger than similarly-shaped scales on occiput; weak supraorbital ridges; weak frontorostral sulcus; canthus rostralis smoothly rounded; eye large (ED / HL 0.21); extra-brillar fringe scales small in general, but larger anteriorly; pupil round; ear opening oval, taller than wide; rostral concave dorsally, dorsal 50 % divided by longitudinal groove; rostral bordered posteriorly by supranasals, one large azygous internasal and nostrils; bordered laterally by first supralabials; 8 R / 8 L (right / left) raised supralabials of similar size, but smallest posteriorly; 7 R / 8 L infralabials, decreasing gradually in size posteriorly; nostrils small, elliptical, orientated dorsoposteriorly; bordered posteriorly by two flat postnasal scales; mental large, triangular, flat, extending to level of second infralabials, bordered posteriorly by two postmentals; mental slightly concave; gular scales smooth, flat, round or oval, juxtaposed; throat scales round, smooth, raised, juxtaposed to subimbricate. Body slender, elongate (AG / SVL 0.44); small, raised, weakly keeled, dorsal scales generally equal in size throughout body, intermixed with numerous, large, multi-keeled, linearly arranged tubercles; enlarged, multi-keeled, conical tubercles on flanks; tubercles extend from the occiput to base of the tail and continue on tail in whorls; body tubercles slightly smaller anteriorly; 18 paravertebral tubercles; pectoral and abdominal scales smooth, flat, imbricate; abdominal scales larger than pectoral and dorsal scales; nine contiguous, pore-bearing, precloacal scales; precloacal pores round to elongate. Forelimbs moderately long, slender; dorsal scales raised, keeled, juxtaposed to subimbricate; ventral scales of brachia smooth, raised, juxtaposed to subimbricate; scales beneath forearm smooth, raised, subimbricate; digits long with an inflected joint; claws recurved; subdigital lamellae unnotched; subdigital lamellae wide throughout length of digits, bearing a larger scale at digital inflections; interdigital webbing absent; fingers increase in length from first to fifth, with fourth and fifth nearly equal in length; relative length of fingers I <II <III <V ≤ IV; total subdigital lamellae on fingers I – V: 14–19 – 25 – 27 – 26 (right), 14–20 – 24 – 26 – broken (left). Hind-limbs slightly longer and thicker than forelimbs; dorsal scales keeled, raised, juxtaposed; ventral scales of thigh and subtibial scales smooth, flat, imbricate; plantar scales smooth, slightly raised, subimbricate; enlarged submetatarsal scales beneath first toes absent; digits elongate with an inflected joint; claws recurved; subdigital lamellae unnotched; lamellae wide throughout length of digits; enlarged scales at digital inflections; interdigital webbing absent; toes increase in length from first to fourth and fifth nearly equal in length; relative length of toes I <II <III
