Chocolate Pipistrelle

The chocolate pipistrelle, Hypsugo affinis (formerly Falsistrellus affinis), is a vesper bat with a head and body of about 9cm and a wingspan of about 24cm. It has a dark brown back with pale grey hair tips giving a grizzled look, a lighter underside, and blackish-brown membranes, ears and bare face (Wikipedia, general species account).

It was described by Dobson in 1871 and is recorded from China, India, Myanmar, Nepal and Sri Lanka. Phylogenetic evidence moved it from Falsistrellus to Hypsugo. The source gives no habitat or diet detail (Wikipedia, general species account).
