Description

Morphological characters of the specimens from Tay Yen Tu NR agreed well with descriptions of Lathrop et al. (1998) and Luong et al. (2019). Size medium (SVL 50.7–53.8 mm, n = 2); head longer than wide (HL 23.4–24.4 mm, HW 19.8–21.7 mm); snout round, longer than eye diameter (RL 8.0–9.0 mm, ED 6.8–6.9 mm); nostrils round, closer to the tip of snout than to eye (NS 3.0– 4.3 mm, EN 5.1–5.8 mm); canthus rostralis distinct, loreal region concave; tympanum distinct; vomerine teeth absent; tongue notched posteriorly. Fore-limbs: Forearm slender, upper arm length (UAL 11.7–11.9 mm), forearm length (FAL 27.1–30.6 mm); relative finger lengths I <II <IV <III, tips of fingers not enlarged; fingers free of webbing. Hind-limbs: Thigh slender (FeL 22.0– 25.8 mm); relative toe lengths I <II <V <III <IV; tips of toes not enlarged; webbing rudimentary. Skin: Dorsal surface of head and body, upper part of flanks with dispersed tubercles; upper eyelid granular; dorsolateral fold absent; ventral surface smooth. Colouration in life: Dorsal surface of head and body brown-copper with a dark marking between eyes; canthus and supratympanic fold brown; upper lip with brown bars; flanks light brown with dark points; dorsal surface of limbs with dark brown transverse bars; ventral surface opaque white (Fig. 2 ).
