Megophrys parva is a species of horned frog found in South Asia and Southeast Asia, from eastern India and Nepal through Bangladesh and Burma to western Thailand and southern China (Yunnan and Guangxi) and northern Laos and Vietnam. Perhaps because of its wide distribution, Megophrys parva is known under many common names, including concave-crowned horned toad, lesser stream horned frog, mountain horned frog, brown horn frog, Burmese spadefoot toad, and small spadefoot toad. It inhabits evergreen broadleaf forests alongside streams.
