Microhyla nilphamariensis

Microhyla nilphamariensis is a small narrow-mouthed frog with a narrow, triangular mouth. It is distinct from other frogs of its genus in having reduced webbing between the toes. The basic back colour is light brown with a distinct dark brown diamond-shaped marking over the back, the throat and chest are brown, the belly is dull white, and the limbs have dark crossbars (Wikipedia, general species account).

It is nocturnal, active when it is raining, and prefers moist environments. Specimens have been seen in a grassy field near ephemeral pools of water. It is found in Bangladesh, India, Nepal and northern Pakistan. The source opened gives no size or breeding details, so none are stated.
