Polypedates bengalensis

Polypedates bengalensis, the brown blotched Bengal tree frog, was first recorded in West Bengal, where it is endemic by the original record, and has since been reported in Odisha and south-western Bangladesh. It has been observed between 7 and 13 metres above sea level (Wikipedia, general species account).

It is a mid-sized frog: males are 4.8-5.4 cm long and females about 7.2 cm. It is yellowish brown to greenish brown, with a series of six to nine dark brown blotches on the body. The digits lack webbing, there is no dermal fold on the forearm, and males have paired vocal sacs (Wikipedia, general species account).
