Description
Morphometrics of the specimens are provided in Suppl. material 5. Morphological characters of the specimens from Hai Phong City and Quang Ninh Province agreed well with the descriptions of Fei et al. (2009) and Fei et al. (2012). Size medium (SVL 48.6-51.7 mm in males, SVL 58.4 mm in females); head longer than wide (HL/HW 1.10-1.13 in males, HL/HW 1.17 in females); snout round in dorsal view, projecting beyond lower jaw; nostril lateral, closer to tip of snout than to eye (NS/EN 0.74-0.91 in males, NS/EN 0.80 in females); canthus rostralis distinct; pupil horizontally oval; loreal region slightly concave and oblique; snout length greater than eye diameter (ED/RL 0.85-0.92 in males, ED/RL 0.83 in females); internarial distance wider than interorbital distance and upper eyelid (IND 5.2-5.6 mm, IOD 4.6-5.1 mm, UEW 3.8-4.2 mm in males; IND 6.7 mm, IOD 5.3 mm, UEW 4.8 mm in females); tympanum distinct, round, smaller than eye diameter (TD/ED 0.60-0.68 in males, TD/ED 0.64 in females); vomerine teeth present, in two oblique ridges; tongue cordiform, deeply notched posteriorly.
Fore-limbs robust, upper arm length shorter than forearm length (UAL/SVL 0.21-23, FAL/SVL 0.44-0.49 in males; UAL/SVL 0.22, FAL/SVL 0.47 in females); fingers free of webbing, relative finger lengths II <I <IV <III; tips of fingers round, not expanded into disc; subarticular tubercles present, formula 1, 1, 2, 2; palmar tubercles prominent, round; inner and outer metatarsal present; nuptial pad on finger I present in males.
Hind-limbs short, thigh longer than tibia (FeL/SVL 0.47-0.49, TbL/SVL 0.51-0.55 in males; FeL/SVL 0.47, TbL/SVL 0.51 in females; tibia approximately five times longer than wide (TbL/TbW 4.44-5.06 in males, TbL/TbW 5.03 in females); tips of toes round, slightly expanded into disc; relative toe lengths I <II <V <III <IV; webbing well developed, formula I1/2-1II1/3-11/2III1/2-2V11/2-0V; subarticular tubercles present, formula 1, 1, 2, 3, 2; inner metatarsal tubercle elongate; outer metatarsal tubercle small and round; tibio-tarsal articulation reaching to between eye and nostril.
Skin: Dorsal surface shagreened with tubercles, more prominent on posterior of dorsum and flank; tiny spinules on upper edge of eyelid, anterior and posterior edge of tympanum; supratympanic fold absent; dorsolateral fold present; dorsal surface of fore-limbs smooth; throat, chest, belly and ventral surface of thigh smooth.
Colouration in life: Iris black, surrounded by red-golden network; dorsum light yellow or grey yellow; flanks yellowish-white or with dark spots; dorsal surface of fore- and hind-limbs brown with dark brown cross bands; upper lip white; throat, chest, belly and ventral surface of thigh cream with dark brown mottling (Fig. 5 View Figure 5 ) (determination after Fei et al. (2009) and Fei et al. (2012)).
Distribution
The species was previously known only from southern China (Zhejiang, Fujian, Guangxi, Hong Kong, Guangdong, Hunan, Jiangxi, Jiangxu and Anhui), including Taiwan ( Frost 2023). The new record of this species in Hai Phong City and Quang Ninh Province, Vietnam is approximately 1,300 km distant from the type locality in Fuzhou, Fujian Province, China.
Ecology
The specimens were found between 19:00 h and 23:00 h on the ground, in small ponds and in small rocky streams. The surrounding habitat was mixed secondary karst forest and evergreen forest of medium hardwoods, shrubs and arrowroot.
Notes
The specimens from Vietnam slightly differ from the type series from China by having a slightly larger size (SVL 48.6-51.7 mm in males, SVL 58.4 mm in females vs. 36.0-40.0 mm in males, 42.0-53.0 in females).
