Nanorana annandalii
Habitat
Montane forest streams and brooks, and pools in forest clearings
Range
North-eastern India (Arunachal Pradesh, West Bengal) and eastern Nepal
Annandale's paa frog, Nanorana annandalii (also Paa annandalii), is a dicroglossid frog first described by Boulenger in 1920. It lives in montane forest streams and brooks and in pools in forest clearings, in north-eastern India (Arunachal Pradesh and West Bengal) and eastern Nepal (Wikipedia, general species account).
It was once treated as the same species as N. gammii, a separation made in 2006 that complicates older records, and deforestation is a threat. The source gives no size, appearance or breeding detail (Wikipedia, general species account).
