Microhyla nilphamariensis

Microhyla nilphamariensis is a small narrow-mouthed frog found in Bangladesh, India, Nepal and northern Pakistan. It has a narrow, triangular mouth and is distinct from other frogs in its genus in having reduced webbing between the toes (Wikipedia, general species account).

The basic colour of the back is light brown with a distinct dark brown diamond-shaped mark, the throat and chest are brown, the belly dull white and the limbs have dark cross bars. It is a nocturnal species, active when it is raining and preferring moist environments, and specimens have been seen in a grassy field near ephemeral pools (Wikipedia, general species account).
