Description
Morphological characters of specimens from Ha Tinh Province matched the descriptions of Fei et al. (2009) and Wu et al. (2022): SVL 28.7–33.2 mm in males (n = 2) and 47.1 mm in the female (n = 1). Head wider than long (HL 10.8–11.4 mm, HW 11.0–12.0 mm, HL / SVL 34.3 – 37.5 %, HW / SVL 36.0 – 38.2 % in males; HL 17.1 mm, HW 17.4 mm, HL / SVL 36.2 %, HW / SVL 37.0 % in the female); snout slightly pointed, projecting beyond upper jaw (RL 4.7–5.3 mm in males and 6.7 mm in the female), longer than horizontal diameter of eye (ED 4.0– 4.1 mm in males and 4.9 mm in the female); canthus blunt; loreal region oblique, concave; nostril lateral, closer to eye than to tip of snout (NS 1.7–2.2 mm, EN 2.1–2.5 mm in males and NS 2.2 mm, EN 3.5 mm in the female); interorbital space flat, broader than upper eyelid and internarial distance (IOD 3.2–3.7 mm, UEW 3.0– 3.5 mm, IN 2.4–2.8 mm in males and IOD 4.4 mm, UEW 4.0 mm, IN 3.6 mm in the female); tympanum distinct, round (TD 2.0– 2.3 mm in males, 3.2 mm in the female); vomerine teeth present; tongue heart-shaped, notched posteriorly; vocal single internal. Fore-limb long (HAL 14.2–16.1 mm in males, 23.3 mm in the female); relative finger lengths I <II <IV <III; fingers with lateral dermal fringes, with basal webbing; tips of finger expanded into wide discs with circum-marginal and transverse ventral grooves; palmar tubercles two; finger I of two males with nuptial pads. Hind-limb slender, thigh shorter than tibia (FL 15.1–16.5 mm, TbL 15.6–16.7 mm in males and FL 22.5 mm, TbL 22.6 in the female); relative toe lengths I <II <V <III <IV; tips of toes expanded into discs, webbing formula I 2 – 2 ½ II 1 ½ – 3 III 1 ½ – 3 ½ IV 3 – 1 ½ V; inner metatarsal tubercle distinct, outer metatarsal tubercle absent; tibiotarsal articulation reaching to the position between the eye and snout when limb adpressed along body.
Skin: Dorsal surface with small tubercles; supratympanic fold present, from posterior edge of eye to axilla; along outer edge of forearm with a row of warts, forming a serrated fringe; along outer edge of tarsus and metatarsus with a series of tubercles forming serrated dermal fringe; below vent with a patch of white pustules; ventral surfaces granulated.
Colouration in life: Dorsal surface yellowish-brown or greenish-brown, with a dark-brown interorbital bar in triangle shape and a dark-brown Y-shaped saddle-like marking on the back; flank light brown with indistinct brownish spots; dorsal limbs brown with dark crossbars; a white conical projection on tibiotarsal articulation; ventral surface with dark-grey mottling, becoming denser on throat, more sparse on chest and belly (Figs 7, 8).
Distribution
In Vietnam, this species was recorded from Lao Cai and Ha Giang Provinces (Frost 2024). Elsewhere, this species is known from China, Laos and Thailand (Frost 2024).
