Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA CHIROPTERA RHINOLOPHIDAE

Scientific Name: Rhinolophus affinis
Species Authority: Horsfield, 1823
Common Name/s:
English Intermediate Horseshoe Bat, Intermediat Horseshoe Bat
Synonym/s:
Rhinolophus andamanensis Dobson, 1872
Taxonomic Notes: This species belongs to ferrumequinum species group. Although Corbet and Hill (1992) and Bates and Harrison (1997) did not include the taxon andamanensis Dobson, 1872 as distinct subspecies, we follow Sinha (1973) in treating it as distinct subspecies. May possibly occur in Sri Lanka (Blyth 1863, Sinha 1973, Bates and Harrison 1997, Simmons 2005) (Srinivasulu et al. in press).

Geographic Range [top]

Range Description: This very widespread 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) (Srinivasulu and Srinivasulu 2005), Bhutan (Gedu), India (Andaman and Nicobar Islands, Arunachal Pradesh, Assam, Sikkim, Tamil Nadu, Uttaranchal and West Bengal) and Nepal (Central and Western Nepal) (Molur et al.2002). 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 (Kock 2000). It has been recorded from 290 to at least 2,000 m asl (China).

Population [top]

Population: It is a highly adaptable and common species.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: In South Asia, this is a highly adaptable species. It roosts in caves, and is found commonly in man-made habitats such as orchards, degraded habitats and agriculture areas (M. Muni pers. comm. February 2002, Molur et al. 2002). 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 caves, and colonies can be large, up to thousands of Individuals. Species forages in understory of forest, and is not thought to be dependent on water. In China it is considered to be a cave roosting species, found both in the wet western highlands and in the more tropical eastern lowlands.
Systems: Terrestrial

Threats [top]

Major Threat(s): There appear to be no major threats to this widespread and somewhat adaptable species. However, limestone extraction may be a threat locally in South Asia (Molur et al. 2002).

Conservation Actions [top]

Conservation Actions: This species has been recorded from a number of protected areas. Other than general research activities, no direct conservation measures are needed for this species as a whole.
