Fore-limb moderate long (FLL / SVL 0.66–0.68); relative length of fingers III> IV> II> I; tips of outer three fingers expanded into discs with circum-marginal grooves; webbing between fingers absent; subarticular tubercles present, oval, formula 1, 1, 2, 2; supernumerary tubercles absent; inner metacarpal (thenar) tubercle large, oval; outer metacarpal tubercle indistinct; glandular nuptial pad on finger I.
Hind-limb relatively long (HLL / SVL 1.78–1.84); tibia longer than thigh length (TL / FL 1.08–1.12); relative length of toes IV> V> III> II> I; all toe tips expanded into discs; webbing between toes deeply incurved, webbing formula I 0–1 / 2 II 0 – 1 III 0 – 1 IV 1 – 0 V; subarticular tubercles distinct, oval, formula 1, 1, 2, 3, 2; inner metatarsal tubercle elongated; outer metatarsal tubercle absent.
Dorsal and lateral surface of head and body smooth with few very small tubercles present on temporal sides of head, above tibiae and vent; supratympanic fold indistinct; dorsolateral fold distinct; ventral surface smooth with flat tubercles on basal ventral thigh.
Colouration in life.
Dorsal sides of head and body green or olive brown with some black dots; lateral side of head and tympanum dark brown or black; a white stripe extending from tip of snout to shoulder on each side; iris pale gold; flanks light brown or brown; dorsal surface of fore-limbs and hind-limbs light brown or brown with dark bands; throat, chest and belly cream with some brown dots; vocal sac orange or light yellow; ventral surface of fore-limbs light red or flesh-coloured; ventral surface of hind-limbs red flesh-coloured or flesh-coloured with some dark brown dots; toe webbing dark brown.

SVL 37.5–41.3 mm in adult males, 61.5–62.5 mm in adult females; head moderate long (HL / SVL 0.35–0.38 in males, 0.35–0.36 in females), longer than wide; snout relatively long (SE / SVL 0.16 in males, 0.15 in females); vomerine teeth present; tympanum distinct, round (TD / ED 0.35–0.40 in males, 0.36–0.37 in females); skin smooth; supratympanic fold indistinct; dorsolateral fold present; fore-limb moderate long (FLL / SVL 0.65–0.72 in males, 0.64–0.66 in females); hind-limb relatively long (HLL / SVL 1.78–1.92 in males, 1.77–1.79 in females); webbing formula I 0–1 / 2 II 0 – 1 III 0 – 1 IV 1 – 0 V; external vocal sac present and finger I with nuptial pad in adult males.
Distribution.
Amolops truongi is currently known from the type locality in Son La Province, north-western Vietnam and Lvchun County, Honghe Prefecture, southern Yunnan Province, China (Fig. 4).
Recommended common name.
We suggest 山罗湍蛙 (Pinyin: shān luó tuān wā) as the Chinese name, deriving from the type locality Son La Province, Vietnam.
