In South Asia, little is known about the habitat or ecology of this species except that this species is found in montane forests and valleys (Molur et al. 2002). In Southeast Asia it has been recorded from wet evergreen forest. In Viet Nam, one specimen has been taken in second growth along a river valley (Smith and Xie 2008). In Chu Yang Sin (Viet Nam) it was captured at 1,100 m a.s.l. in a wet pristine mixed forest. It may be an aerial hawker bat (Kruskop 2013). It also occurred at lower elevation (260 m a.s.l.) in Cambodia (Phauk et al. 2013).

This species ranges from northeastern South Asia, into southern China, and mainland Southeast Asia. In South Asia, this species is presently known from India (Nagaland and West Bengal) (Das 2003, Molur et al. 2002), it has been recorded from around 1,100 m asl. In China it is known only from a single record from Yunnan (Wang 2002, Smith and Xie 2008). In Southeast Asia, it ranges from northern Thailand (Corbet and Hill 1992), probably through much of Lao PDR (Francis et al. 1999, Thomas et al. 2013) and in Cambodia (Hendrichsen et al. 2001, Phauk et al. 2013). It also occurs in Viet Nam (Kruskop 2013, Görföl and Tu pers. comm.).

In South Asia, there are no conservation measures in place, and this species is not recorded from any protected areas. Surveys, ecological and populations studies are recommended (Molur et al. 2002). The species has been recorded from protected areas in Cambodia and Lao PDR (C. Francis pers. comm.) as well as from Vietnam (Görföl and Tu pers. comm.).
