Description:
This very common species is present
throughout much of South Asia, southern and central China and Southeast Asia.
In South Asia, this species is presently known from Bangladesh (Sylhet
division), Bhutan (Gedu), India (Andaman and Nicobar Islands, Arunachal
Pradesh, Assam, Sikkim, Tamil Nadu, Uttaranchal and West Bengal) and Nepal (Central
and Western Nepal). In China, it has been reported from Hunan, Shanxii, Hubei,
Guizhou, Sichuan, Yunnan, Zhejiang, Fujian, Jiangxi, Guangdong, Hong Kong,
Guangxi, Jiangsu, Anhui and Hainan island. In Southeast Asia, it ranges from
Myanmar in the west, through Thailand, Lao PDR and Viet Nam, into Peninsular
Malaysia, Indonesia (Sumatra, Java and the Lesser Sunda Islands), to southern
parts of the island of Borneo (Indonesia and Malaysia). Reports of this species
from Cambodia cannot currently be confirmed .

MORPHOLOGICAL
DESCRIPTION:
· Dorsal fur is darker or lighter brown, sometimes coriaceous
buff. Ventral fur is from brown to cream-buff.
·
Juveniles are lighter than adults. · A medium to fairly large horseshoe bat. Over its range, forearm length varies between 46.0- 55.5mm. Body masses 13.5 - 14.6 g. Forearm lengths of horseshoe bats 50.2-54.9 mm.
Habitat and
Ecology:
In South Asia, this is a highly adjustable
species. It roosts in cavities, and is found commonly in man-made habitats such
as plantations, degraded habitats and agriculture areas. In Southeast Asia, it
has been recorded from primary and secondary forest, occasionally in cultivated
areas, but is not found in urban areas. It has a tendency to roost in cavities,
and colonies can be large, up to thousands of Individuals. Species searches in
understory of forest, and is not thought to be dependent on water. In China it
is considered to be a cavity roosting species, found both in the wet western
highlands and in the more tropical eastern lowlands.
MAJOR
THREAT(S):
There appear to be no major threats to this
prevalent and slightly adaptable species. However, limestone abstraction may be
a threat locally in South Asia.
