Identification
Studied Specimens: One adult specimen TYT 2010.24 (SVL 29.16 mm), and two immature specimens VH13 (SVL 17.58 mm) and TYT 2010.35 (SVL 16.11 mm). Body of medium size, triangular in shape; the loreal region is slightly oblique, the snout is slightly rounded, and is longer than the eye diameter (SL 3.87 mm, ED 2.59 mm). Males possess vocal sacs. The tongue is oval, rounded posteriorly. The eye diameter is wider than the upper eyelid, approximately 4/5 the length of the snout (ED 2.79 mm, UEW 2.26 mm, SL 3.87 mm); nostrils are round, situated closer to the tip of the snout than to the eye; the internarial distance is slightly narrower than the interorbital distance (IOD 2.98 mm). The pupils are round, the tympanum is indistinct; males possess vocal sacs. Fingers lack webbing; toes 1/2 webbed; the inner metatarsal tubercle is oval, the outer metatarsal tubercle is round, white. When the hind limbs are adpressed along the body, the tibiotarsal articulation reaches or slightly surpasses the eye.

Biology and Ecology
Similar to Microhyla ornata. Commonly found in moist areas within evergreen forests, fields, streamsides, and gardens. The breeding season typically spans from March to June, depending on the distribution area. During the day, they hide in depressions in the ground or crevices in the earth, and are active and forage at night, only appearing during the rainy season. Their primary food sources are ants, termites, and terrestrial insects.
Distribution
Vietnam: Primarily distributed in the North, extending to Gia Lai, Kontum, and Dak Lak provinces.
