Identification:
A small frog with a body length of 18-28 mm. The snout is slightly pointed, extending beyond the lower jaw. The canthal ridges are indistinct. The cheek region is slightly concave, and the eyes are small, with the eye diameter equal to the width of the upper eyelid. The fingers are entirely free, with blunt tips. The first finger is shorter than the second. The toes lack discs, and webbing is present on less than half of the toes. The outer metatarsal tubercle is larger than the inner metatarsal tubercle. The tibiotarsal articulation does not reach the eye. The body is grayish-brown, with symmetrical dark brown spots on the back, extending from behind the eyes to the end of the body, narrowing at the shoulder and posterior regions. Sometimes, there are a few very thin white stripes down the middle of the back, smaller than those found in Microhyla haymonsi. The abdomen is opaque white, and the chin and throat are pinkish-brown.
Biology and Ecology:
Similar to Microhyla pulchra. Despite its small size, the species has a large vocal sac, aided by a resonating chamber in its throat, allowing for loud and far-reaching calls. They typically appear during the rainy season each year in well-preserved forest areas up to an elevation of 2000 meters. They are occasionally found in some agricultural areas. Their primary food sources are ants, termites, and other terrestrial insects.
Distribution:
Vietnam: Distributed in northern Vietnam extending south to Gia Lai, Kontum, Dak Lak, and Lam Dong provinces, up to an elevation of 1,600 – 1,800 meters.
Global: Bangladesh; Bhutan; India; Nepal; Pakistan; Sri Lanka
