Grass and leaf litter; semi-buried on the forest floor
Size
Males about 24mm, females about 28mm snout-vent
The ornate narrow-mouthed frog is a small microhylid with a small head, no teeth, no discernible eardrum and an arrow-shaped mark on the back, generally yellowish with dark brown patches. Males are about 24 mm from snout to vent and females about 28 mm. It occurs in Bangladesh, Bhutan, India, Nepal, Pakistan and Sri Lanka, and was once treated as the same species as Microhyla fissipes (Wikipedia, general species account).
It lives semi-buried in leaf litter and grass, is mainly nocturnal but also active by day in the rainy season, and breeds in ponds and temporary rain pools. In some habitats it shelters in elephant dung. Nationally Least Concern (Sri Lanka National Red List 2012).
