Morphological measurements of the specimen (Fig. 1) are provided in Table 2. SVL 22.9 mm; head moderate long (HL / SVL 0.38), slightly longer than wide (HL / HW 1.08); snout moderate long (SL / SVL 0.16), projecting beyond lower jaw; canthus rostralis distinct; loreal region slightly concave; distance from nostril to snout tip slightly smaller than distance from eye to nostril; internarial distance slightly greater than interorbital distance (INS / IOS 1.07); upper eyelid width almost equal to interorbital distance (UEW / IOS 1.05); pupil oval, horizontal; tympanum distinct, small (TD / ED 0.27); tympanum to eye distance greater than tympanum diameter; pineal spot present, indistinct.
Fore-limb relatively long; relative length of fingers III> IV> II> I; tips of outer three fingers expanded into discs, circummarginal grooves present on tips of outer three fingers, absent on first finger; webbing between fingers absent; subarticular tubercles distinct, oval, formula 1, 1, 2, 2; supernumerary tubercles absent; metacarpal tubercles indistinct.
Hind-limb moderate long; tibia almost equal to femoral length (TIB / FEM 1.03); relative length of toes IV> V> III> II> I; all toe tips expanded into discs with circummarginal grooves; webbing between toes deeply incurved; subarticular tubercles distinct, oval, formula 1, 1, 2, 3, 2; supernumerary tubercles absent; inner metatarsal tubercle elongated; outer metatarsal tubercle absent.
Dorsal and lateral surfaces of head and body smooth; dorsal surface of fore-limb smooth, dorsal surface of hind-limb with many small tubercles; supratympanic fold present; discontinuous glandular dorsolateral fold from rear of eye to near vent; ventral surface smooth.
Colouration in life
Dorsal surface of the head and body green, some small black spots on dorsum; dorsal surface of limbs yellowish-green with some brown crossbars; lateral surface of head light green, a black stripe below canthus rostralis from snout tip across eyes to supratympanic fold; upper lip light yellowish-green with irregular brown spots; lateral surface of body light green, a large brown spot just behind supratympanic fold on each side; ventral surface of head light yellow, lower lip yellowish-brown; ventral surface of light greenish-yellow; ventral surface of limbs yellowish-brown (Fig. 2).
Ecological notes
This specimen was found at night in the shrubland near a river on a leaf of an herbaceous plant (Fig. 3). Other amphibian species found in sympatry include Nanorana blanfordii (Boulenger, 1882), N. liebigii (Günther, 1860), Raorchestes yadongensis Zhang, Shu, Liu, Dong & Guo, 2022 and Xenophrys pangdaensis Shu, Li, Wu, Liu, He, Li, Zhang & Guo, 2023.
