Description

Adult males measure 16–17 mm (0.6–0.7 in) and adult females, based on a single specimen, about 19 mm (0.7 in) in snout–vent length. The snout is blunt. The canthus rostralis is rounded. The tympanum is hidden. The fingers have poorly developed discs and no webbing. The toes have webbing, lateral fringes, and more developed discs. Skin is smooth. The dorsum is pinkish grey-brown, and there is a blackish lateral stripe. There is a dark brown mid-dorsal marking, but this is indistinct in some specimens. The venter is white with black marbling. [2]

Habitat and conservation

Microhyla karunaratnei occurs in shaded, wet leaf litter in tropical moist forest at elevations of 515–1,110 m (1,690–3,642 ft) above sea level. The tadpoles develop in wetlands, including old abandoned gem mining pits, [1] the creation of which may actually have benefited the species. [2] However, Microhyla karunaratnei is an uncommon species that is known only from two sites. It is threatened by habitat loss caused by expanding cardamom plantations and by agricultural pollution. It occurs in the Sinharaja Forest Reserve. [1]

<i>Microhyla sholigari</i>

Microhyla sholigari is a species of microhylid frog endemic to southern India. It was described from the Biligirirangan Hills in Chamarajanagar district, Karnataka and is named after the Soliga tribal people living in the forests in and around these hills. The frog was thought to be endemic to the Western Ghats and known only from the type locality and another location in Kerala and was listed as an Endangered species. A recent study reported the species from 15 localities in the central Western Ghats with individuals sighted near the Bannerghatta National Park, Bangalore, Karnataka. The study supplemented the original species description with color photographs, call recordings and provided a re-assessment of the threat status as per the IUCN Red List and suggest the status as Least-concern species because the criteria for classifying it as an endangered species are no longer fulfilled.
