Amolops monticola

Amolops monticola, the mountain sucker frog or mountain torrent frog, is found in north-east India, eastern Nepal and western China (Tibet and Yunnan), although there is some uncertainty about the Chinese records. It probably also occurs in Bhutan, in between. It grows to a snout-vent length of 74 mm (Wikipedia, general species account).

As is characteristic of its species group, the skin is smooth, dorsolateral folds are present, and the side of the head is dark with a light upper-lip stripe extending to the shoulder. The tympanum is distinct, the finger and toe tips bear discs, and males have paired vocal sacs. Tadpoles measure up to 66 mm in total length, about two thirds of it tail (Wikipedia, general species account).
