Description
Morphological characters of the specimen from Ha Tinh Province relatively matched descriptions of Boulenger (1893), Bourret (1942), Fei et al. (2009), Pham et al. (2019 a) and Lyu et al. (2023): SVL 41.8 mm in male (n = 1); head longer than wide (HL 15.4, HW 15.0 mm, HL / SVL 36.8 %, HW / SVL 35.9 %); snout obliquely truncate, projecting beyond upper jaw (RL 5.5 mm), longer than horizontal diameter of eye (ED 4.8 mm); loreal region concave; canthus rostralis well developed; nostril lateral, slightly closer to eye than to tip of snout (NS 2.8 mm, EN 2.5 mm); interorbital space flat, broader than upper eyelid and narrower than internarial distance (IOD 4.3 mm, UEW 3.9 mm, IN 4.8 mm); tympanum distinct (TD 3.0 mm); vomerine teeth present; tongue heart-shaped, round posteriorly; vocal in male present.
Fore-limb slender (HAL 15.7 mm); relative finger lengths I ≤ II <IV <III; fingers without dermal fringe, free of webbing; tips of fingers round, not swollen; subarticular tubercles indistinct; palmar tubercles indistinct; nuptial pads absent in males. Hind-limb slender, tibia longer than thigh (TbL 19.8 mm, FL 18.5 mm); relative toe lengths I <II <V <III <IV; tips of toes round, slightly swollen; webbing rudiment; toes dermal fringe absent; metatarsal tubercle indistinct; subarticular tubercles indistinct; tibiotarsal articulation reaching to anterior corner of eye when limb adpressed along body.
Skin: Dorsal surface smooth, with sparse small granules; dorsum with a weak discontinuous V-shaped ridge; dorsolateral ridges discontinuous; flanks with small glandular warts; supratympanic fold present, from posterior corner of eye to axilla; outer margin of upper eyelid with weak medial bumped appendage; around cloaca with small tubercles; ventral surface smooth.
Colouration in life: Dorsal surface light yellowish-brown; a dark brown triangular marking between eyes; upper lip with vertical dark bars; ventral surface white, a round white spot present on each side of the chest; ventral surface of limbs reddish (Fig. 3).
Distribution
In Vietnam, this species has been recorded from Dien Bien, Lai Chau, Lao Cai, Ha Giang, Son La and Thanh Hoa Provinces (Nguyen et al. 2009, Orlov et al. 2015, Luong et al. 2019, Pham et al. 2019 a and Frost 2024). Elsewhere, this species is known from China, Myanmar, Laos and Thailand (Lyu et al. 2023) (see discussion).

Notes
The specimen from Ha Tinh differs from the description of Lyu et al. (2023) in having relative finger lengths I ≤ II <IV <III (vs. II <IV <I <III) and dorsum with a small dark X-shaped marking (vs. larger dark X-shaped marking).
