Small size frog, body triangle, adult male with SVL 19.9 mm; head length (HL 6.2 mm, 32.1% of SVL) slightly longer than width (HW 5.8 mm, 29.1% of SVL); snout rounded in profile, projecting beyond the lower jaw, its length (SL 2.9 mm, 14.6% of SVL) longer than horizontal diameter of eye (ED 1.9 mm, 9.5% of SVL); canthus rostralis round, loreal region vertical and slightly concave; interorbital space flat , larger (IOS 2.1 mm, 10.6% of SVL) than width of upper eyelid (UEW 1.4 mm, 7.0% of SVL) and internarial distance (INS 1.9 mm, 9.5% of SVL); snout longer than eye diameter (SL/ED 152.6%); tympanum hidden; vomerine teeth absent; tongue posteriorly oval and not notched behind; supratympanic fold weak, extending from posterior corner of eye to arm insertion; male with internal single subgular vocal sac; nuptial pad absent (Fig. 3 ). Forelimbs slender; lower arm length (LAL 3.4 mm, 17.1% of SVL) shorter than hand length (HAL 4.8 mm, 24.1% of SVL); relative finger lengths: I<IV<II<III; tips of all fingers slightly enlarged; no webbing between fingers; subarticular tubercles distinct, round, formula: 1, 1, 2, 2; three metacarpal tubercles, middle metacarpal tubercle oval, smaller than outer and inner metacarpal tubercle and not contacting outer or inner metacarpal tubercle (Fig. 3 ). Hind-limbs long, tibia (TL 10.5 mm) about half SVL and shorter and foot (FL 52.8 mm); relative length of toes: I<II<V<III<IV; tibiotarsal articulation reaching between nostrils and eyes; heels overlapping when thighs are positioned at right angles to the body; tips of toes rounded and not swollen; rudimentary webbing between toes; subarticular tubercles distinct, round, formula 1, 1, 2, 3, 2; inner metatarsal tubercle elongated, outer metatarsal tubercle prominent, large (Fig. 3 ). Dorsal skin surface relatively smooth with small tubercles; ventral surfaces of body and limbs smooth; flanks of body relatively smooth (Fig. 3 ). In preservation. Dorsal surfaces of body and limbs greyish or brown, with usually a yellow hair-fine median line from snout to anus and two very small black spots on back, forming " ()" -shape; ventral surfaces of body whitish obscured by many brown marblings; flanks and lateral side of head dark with a dark lateral stripe; ventral side of throat of adult male black; dorsal parts of limbs, fingers and toes with brown crossbars (Fig. 3 ). Distribution Microhyla hmongorum was previously known in Lai Chau Province, northern Vietnam, Phongsali and Luang Prabang Provinces of Laos and Kachin of Myanmar ( Hoang et al. 2022 ). Our study further extends the species' distribution range northwards to Mengla, Xishuangbanna and Yuanyang, Honghe, Yunnan Province, China. Ecology The species is often found in areas that are highly disturbed by human activity. The habitat of the species mainly includes paddy fields, still ponds and rain puddles. Breeding season of the species is mainly during April to September. This species is in sympatric distribution with M. butleri , M. mukhlesuri and F. multistriata . Notes Morphological characters of the specimen from China agreed well with the original description of Hoang et al. (2022) . Based on the type locality in northern Vietnam, we suggest "Yue Bei Jī Wa ( 越北姬蛙)" as its Chinese common name.
