Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA CHIROPTERA VESPERTILIONIDAE

Scientific Name: Pipistrellus tenuis
Species Authority: (Temminck, 1840)
Common Name(s):
English Least Pipistrelle, Indian Pygmy Bat
Synonym(s):
Pipistrellus mimus Wroughton, 1899
Pipistrellus mimus Wroughton, 1912 subspecies glaucillus
Pipistrellus mimus Wroughton, 1899 subspecies mimus
Pipistrellus mimus Thomas, 1915 subspecies principulus
Pipistrellus principulus Thomas, 1915
Vespertilio tenuis Temminck, 1840
Taxonomic Notes: Pipistrellus tenuis probably represents a complex of several similar species. Further studies are needed to clarify the taxonomic status of populations currently allocated to this species. This taxon belongs to the coromandra subgroup of pipistrellus species group. Ellerman and Morrison-Scott (1951) and Sinha (1999) considered Pipistrellus mimus Wroughton, 1899 to represent forms from South Asia. The taxon glaucillus Wroughton, 1912, considered earlier as distinct subspecies, has been synonymized following Sinha (1980) (Srinivasulu et al. in press). We follow the IUCN SSC Chiroptera Specialist Group (P. Racey pers. comm. 2008) in recognizing Pipistrellus murrayi as distinct from P. tenuis.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Francis, C., Rosell-Ambal, G., Tabaranza, B., Lumsden, L., Heaney, L., Gonzalez, J.C. & Paguntulan, L.M.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Justification:
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description: This widespread species is found throughout much of South Asia, southeastern China and Southeast Asia. In South Asia, this species is presently known from Afghanistan (Nangarhar Province), Bangladesh (Chittagong and Sylhet divisions), India (Andhra Pradesh, Arunachal Pradesh, Assam, Bihar, Chhattisgarh, Gujarat, Haryana, Himachal Pradesh, Jharkhand, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Manipur, Meghalaya, Nagaland, Orissa, Rajasthan, Tamil Nadu, Tripura, Uttar Pradesh, Uttarakhand and West Bengal), Nepal (Central and mid western), Pakistan (North West Frontier Province, Punjab and Sind) and Sri Lanka (Central, North Central, North Western, Sabaragamuwa, Southern, Uva and Western provinces) (Das 2003, Korad et al. 2007; Molur et al. 2002; Vanitharani 2006). It has been recorded form sea level to 769 m asl (Molur et al. 2002). It is present over much of southeastern China, including the island of Hainan (Smith and Xie 2008). In Southeast Asia, it is found throughout the mainland, ranging into Indonesia (Sumatra, Java, Bali, Lombok, Sulawesi, Seram and Serasan), the island of Timor (East Timor and Indonesia), Borneo (Indonesia, Malaysia and possibly Brunei; the species is possibly more widespread than currently known [C. Francis pers. comm.) and the Philippines, where it has been recorded on Cebu (Paguntalan pers. comm. 2006), Luzon (Rizal Province), Mindanao (Taylor 1934), Negros, and Sibuyan (Heaney et al. 1998) where it occupies an altitudinal range from sea level to 800-1700 m (P. Bates and L. Heaney pers. comm. 2006).

Population [top]

Population: In South Asia, this species is widely distributed and common, and the population is stable and seems to be doing well (Molur et al. 2002). It is widespread and moderately common in the Philippines (Heaney et al. 1998). It is locally very common in Myanmar and Lao PDR (Bates et al. 2005).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: In South Asia, this species is found from arid zones to wet and humid areas. It is equally abundant in forested areas, in rural and urban landscapes (C. Srinivasulu pers. comm. 2007). It roosts in hollows of trees, holes, crevices and cracks in walls and ceilings of old buildings, dead leaves of trees. In Southeast Asia this is a largely forest species inhabits primary and secondary hill, montane and montane mossy forest (Heaney et al. 1998). It is adapted to highly disturbed habitats, gardens, and mangrove forests (P. Bates pers. comm. 2006). It is an early flyer, with a varied flight pattern from a jerky flight with many twists and turns to a slow fluttering and floating flight to an erratic flight as the evening progresses. Its diet is varied and seasonal. It feeds on beetles, cockroaches and wingless ants in winter, on a wide variety of insects in summer and on winter termites, moths, hymenopterans, dipterans and beetles during monsoon. There are two breeding seasons one in February-March and the other in July-August and between one to three young are born (Bates and Harrison 1997).
Systems: Terrestrial

Threats [top]

Major Threat(s): There appear to be no major threats to this widespread and somewhat adaptable species.

Conservation Actions [top]

Conservation Actions: In Southeast Asia the species has been recorded from many protected areas. In South Asia, the species has been recorded from protected areas in India like Satpura National Park in Madhya Pradesh, Agasthiyamalai Biosphere Reserve in Tamil Nadu (Vanitharani 2006) and Nagarjunasagar Srisailam Tiger Reserve in Andhra Pradesh (C. Srinivasulu pers. comm. 2008). Further studies are needed into the taxonomy, distribution, abundance, reproduction and ecology of this species. Populations of this species should be monitored to record changes in abundance and distribution (Molur et al. 2002).
