Description of the specimen from China.

Measurements are presented in Table 2 . Body size small (SVL 29.4 mm); head strongly depressed, length and width almost equal (HL 12.4 mm, HW 12.7 mm); snout short (SNL 4.9 mm), pointed and truncated; eye large (ED 3.8 mm), pupil circular; canthus rostralis indistinct, loreal region oblique, slightly concave; interorbital distance wider than internarial distance and upper eyelid width (IOD 3.4 mm, IN 2.7 mm, UEW 2.7 mm); distance between anterior corners of eyes (DAE 6.5 mm) about 60.2% distance between posterior corners of eyes (DPE 10.8 mm); nostril oval, nearer the tip of snout; tympanum distinct, diameter (TYD 2.1 mm) less than eye diameter, tympanum separated from eye by distance (TYE 0.9 mm) 42.9% of tympanum diameter; pineal ocellus absent; supratympanic fold distinct, interrupted, extending from behind eye to beyond level of axilla, composed of large irregular glandular ridges; vomerine teeth arranged in two small oblique groups between choanae and widely separated from each other; tongue large, accounting for almost half of mouth, heart-shaped, dorsal surface smooth, notched and free posterior.

Forelimbs slender (FLL 6.3 mm, HAL 16.2 mm); relative length of fingers: I <II <IV <III; tips of fingers dilated into large, rounded and flattened discs; subarticular tubercles large and distinct, with indistinct supernumerary tubercles; formula of subarticular tubercles: 1, 1, 2, 2; outer edge of fourth finger distinctly serrated. Hindlimbs slender, tibia longer than femur length and foot length (TbL 15.8 mm, FeL 15.7 mm, FoL 13.3 mm), tibiotarsal articulation reaching posterior edge of snout when hindlimbs pressed forward; relative length of toes I <II <V <III <IV; webbing formula I(1/3) - (1)II(0) - (1/2)III(0) - (1)IV(1) - (1/3)V; tips of toes dilated into rounded, flattened discs, smaller than discs on fingers; large subarticular tubercles roundish, formula of subarticular tubercles: 1, 1, 2, 3, 2; large inner metatarsal tubercle oval and raised (IMT 1.7 mm), outer metatarsal tubercle absent; outer edge of fifth toe with five distinct serrations.

Dorsal surface of head, body, and limbs very rough, with large irregular glandular ridges ordered symmetrically in middle vertebral region; a large, horn gland behind head roughly in X-shape; large conical tubercles on back of thighs near vent; lateral parts of body become granular, dense small tubercles below eye and 4-5 large tubercles behind tympanum on each side; throat and chest relatively smooth; belly and ventral surface and underside of thigh with thickened flat granules; axillary region and underside of tibia smooth.

Coloration in life.

Dorsal surface of head and body green with irregular olive patches; tips of most tubercles red on olive patches and light green on other regions; dorsal surfaces of limbs green with dark olive bands, tips of tubercles red on bands and light green on other regions, finger and toe discs light green; lateral surface of head green, iris yellowish green with irregular black reticulation; tympanum dark olive; flanks light yellow with black patches and strips; ventral surface of head and body brownish black with many small white dots; a light yellow patch on anterior region of the base of forelimb on each side; ventral surface of limbs brownish black with some small white dots on ventral thigh and some light yellow patches on other regions of ventral limbs.

Distribution.

This species is currently known only from the type locality in Ha Giang Province, northeastern Vietnam, and Xichou County, Wenshan Prefecture, southeastern Yunnan, China.
