Taxonomy
The bat was formerly considered a subspecies of H. cineraceus by Blyth in 1853, but is now commonly considered a distinct species. The species was first recognized as a separate species by Topál in 1975. It belongs to the bicolor species group.
The holotype was collected from the Jabalpur district of Madhya Pradesh in 1970.[1]
Description
The fur is soft and brown to reddish-brown on the
The tail of the bat projects beyond the interfemoral membrane, and the baculum is 1.3mm long, with a C- shape. The presence of a well-developed internarial septum of peculiar shape (with a short base and a bulbous apex), the fact that the tail projects beyond the interfemoral membrane, and the conspicuous C-shape of the baculum are some of the characters of H. durgadasi which render this species distinct from its sister species.[4]
Biology
Diet
The bat feeds on beetles, crickets, and other small insects.[1]
Echolocation
The bat echolocates at a frequency of 168.4–175.7 kHz. This is a much higher frequency than H. cineraceus, despite the bat being larger than the latter species.[5]
Habitat and distribution
The bat is endemic to India and known from the villages of Katangi, Katanga and Richhai in the district of Jabalpur in Madhya Pradesh and the villages of Hanumanahalli and Therahalli in the Kolar district of Karnataka. In 1998, a team from the Zoological Survey of India also found 9 individuals in a roost site in Loyudhan Falls in the Mirzapur district of Uttar Pradesh.[4]
However, specimens of H. durgadasi have not been spotted in the original type locality for almost 30 years.[1][6]
The bat's known range extends over 114,335 km2, however, the bat only occupies around 2,000 km2 of that. It inhabits areas from 347 to 900 m above sea level.
The bat roosts in colonies of several individuals in cave systems and is also found roosting below large granite boulders and in caves. It has been observed roosting with other species of bat, but has also been found to roost purely with members of its own species in a cave.
The bat mainly forages in dry tropical deciduous forest and tropical thorn forest.[1]
Conservation
The bat is listed as vulnerable by the IUCN because of its limited area of occupancy, its scattered and limited population, the continuing decrease in its population, and continuing degradation of its habitat.
The main threat to the bat is that of habitat loss caused by stone
The bat is not protected by any legal bill or agreement, and the habitat of the bat does not overlap with any protected areas. However, further studies are need to ascertain the true range of this species, as some populations may be confused with populations of H. cineraceus, H. ater and ater like taxa.[1]
