The adult male frog measures 52.80-61.50 mm in snout-vent length and the adult female frog 82.50-94.40 mm. The skin of the dorsum is olive-green in color with round or irregular brown blotches. The sides of the head are also olive-green in color with brown marks. The legs are yellow with red-brown marks. [4]

Habitat

This frog lives in canopied forests, where it has been found in and near fast-flowing streams, especially in the splash areas on rocks. Scientists observed this frog between 80 and 1580 meters above sea level. [1]

Scientists have seen the frog in some protected parks: Mayeng Hill Reserve Forest, Kolaghat Reserve Forest, Garbhanga Reserve Forest, Amchang Wildlife Sanctuary, and Nongkhylem Wildlife Sanctuary. [1]

Threats

The IUCN classifies this frog as vulnerable to extinction. Its principal threats include habitat loss in favor of agriculture and human habitation. Scientists consider overharvesting a possible threat, but it has yet to be confirmed. [1]
