A long tail completely enclosed in the interfemoral membrane except for the extreme tip. The forearm length averages 90.1 mm (85.4 - 95.0 mm). The noseleaf is complex and has four pairs of supplementary leaflets, the fourth is distinctly smaller than the other three. Tragus absent, anti-tragus well defined. Wings and interfemoral membranes are naked and uniform dark brown. Pelage is soft, dense and long. Dorsal surface is pale brown to dark brown. Ventral surface uniform grey brown.
This species can be separated from similar looking H. lankadiva 1. basing on larger ears (E 26.0 - 34.0 mm vs 19.5 - 30.0 mm) and 2. complex noseleaf vs simple noseleaf in H. lankadiva.
A common species of South Asia found in montane forests and tropical evergreen and semi evergreen forests. Colonial, roosts in large colonies in diurnal roosts located in subterranean caves, lofts of houses and sheds at high altitudes ranging from 1380 m to 1910 m asl. Individuals leave the roost just after sunset. It hunts in the canopy and circles around trees while in pursuit of insects. This species breeds once a year, two pups to each female.
