Fur on the wings above and below extending outwards from the middle of the

and below nude, with the exception of a few straggling hairs. 
Basal and terminal portions of fur light yellowish-brown above or fawn-coloured ; 
under parts paler or ashy white. Muzzle fleshy brown; membranes light brown, with 
a whitish margin. 
Single upper incisor perfectly simple. Upper premolar large, longer than the
