Description

Adult medium-sized male, body flat (SVL 47.8 mm); head moderate larger than one-third of snout-vent length (HL / SVL 0.36); head length slightly larger than width ( HW / HL 93.0 %); snout blunt, round, obtuse beyond lower jaw in ventral view; snout length slightly less than half of head length (SL / HL 46.8 %); dorsal head slightly concave; canthus rostralis distinct; loreal region slightly concave, near vertical; nostril oval, closer to snout than eyes (SN / N-EL 43.4 %); internarial distance less than interorbital distance ( IND / IOD 79.2 %), but larger than upper eyelid width ( IND / UEW 105.0 %); eyes large, about one-third of head length ( ED / HL 32.7 %); tympanum distinct, oval, larger than two-third of eye diameter ( TD / ED 69.6 %); supratympanic fold distinct, slender, extend from posterior eye to above shoulder; maxillary teeth single row, small; tongue heart-shaped, deeply notched posteriorly, posterior 1 / 3 free; vomerine teeth two short rows, prominently, untouching inner front edges of choanae, separated by distance less than length of each series; male with internal subgular vocal sacs, vocal sac opening on floor of mouth at each corner (Fig. 3 ).

Fore-limbs robust; lower arm and hand length slightly less than half of SVL ( LAHL / SVL 48.7 %), hand length less than one-third of snout-vent length ( HAL / SVL 29.9 %); fingers slender, dorsally compressed, webbing free, relative length of the fingers: III> IV> II ≈ I; fringe present, weakly developed; fingers tips nearly rounded, dilated into large disc distally, circummarginal grooves present; subarticular tubercles prominent, rounded, formula 1, 1, 2, 2; supernumerary tubercle absent; metacarpal tubercles three: inner metacarpal largest, oblong elliptical; outer metacarpal smallest, rounded; middle one moderate, oval; nuptial pad present on dorsal base of first finger (Fig. 3 ).

Hind-limbs slender, long ( HLL / SVL 158.8 %); tibia length slightly longer than thigh length (TL / THL 97.9 %), much longer than foot length ( FL / SHL 83.1 %), slightly longer than half of SVL; tibia-tarsal articulation reaching beyond anterior border of eye when hind-limbs are stretched alongside body; heels overlap when legs held at right angles to body; relative length of toes IV> III> V > II> I; toe tips dilated into large disc with circummarginal grooves, nearly rounded, smaller than discs on fingers; toes half-webbed; subarticular tubercles distinct, round, formula: 1, 1, 2, 3, 2; supernumerary tubercle absent; inner metatarsal tubercle present, oblong; outer metatarsal tubercle absent; no tarsal fold (Fig. 3 ).

Dorsal skin relatively smooth with small granular, dorsolateral fold absent; throat smooth with small tubercles, indiscernible; chest, belly and ventral thigh speckled with small tubercles (Fig. 3 ).

Colouration in preservative

Dorsal surface is faded to greyish-brown, mottled with dark patches; transverse bars on the back of the limbs; black stripes under the temporal fold; ventral surface creamy white, with brown pigment particles on the chest.

Distribution

Our study further extends the species' distribution range to Yunnan, China. Therefore, the species currently known from the Dehong Prefecture, south Yunnan, China, eastern Nepal, Bhutan, India, Bangladesh and Myanmar.

Ecology

This species often inhabits evergreen broad-leaved forests. We found it in the shrubbery by the stream during summer nights. This species is in sympatric distribution with Amolops afghanus and Zhangixalus smaragdinus .

Notes

Chinese Names We suggest “ Tè Lài Fàn Shù Wā (南亚泛树蛙) ” as its Chinese common name.
