Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA CHIROPTERA MOLOSSIDAE

Scientific Name: Cheiromeles parvidens
Species Authority: Miller & Hollister, 1921
Common Name/s:
English Lesser Naked Bat
Taxonomic Notes: There is a need for studies of geographic variation across the species' range (L. Heaney, K. Helgen and D. Balete pers. comm. 2006).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Csorba, G., Bumrungsri, S., Francis, C., Bates, P., Gumal, M. & Kingston, T.
Reviewer/s: Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority), Chanson, J. & Chiozza, F. (Global Mammal Assessment Team)
Justification:
Listed as Least Concern because its extent of occurrence is greater than 20,000 km², although there is very little information known about its population status, and there are some major threats, it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description: This species occurs on Buton (T. Kingston pers. comm. 2006), Sanana, Sulawesi and Sulu Islands (Indonesia) (Lawrence 1939; Simmons 2005; Flannery 1995) and throughout the Philippines, except Palawan (Ingle and Heaney 1992), where it is reported from Mindoro (Lawrence 1939), Mindanao (Davao del Sur, Misamis Oriental, and South Cotabato provinces), and Negros (Heaney et al. 1998). There is a record from Tawi-tawi (K. Helgen pers. comm. 2006).

Population [top]

Population: The population status of this species is unknown as there have not been many appropriate surveys.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: The species is not well known, but it probably occurs in agricultural areas from sea level up to 200 m asl. It has often been found roosting in hollow trees (Rabor 1986; Taylor 1934; Heaney et al. 1998). The record from Sanana Island is from secondary forest near a village (K. Helgen pers. comm. 2006).
In the Philippines these bats are known to roost in coconut palms, hollow trees, and occasionally in caves (Ingle and Heaney 1992). They have been found flying low over the mouth of a stream on Sunana Island (Flannery 1995). These bats are insectivores and are thought to have two young at a time that are left in the roost when the adult bats go to forage (Nowak 1999).
Systems: Terrestrial

Threats [top]

Major Threat(s): Deforestation is occurring throughout its range. In the Philippines, much of the lowland forest has been lost. As this species is a large microbat, it is hunted in Sulawesi in large numbers (K. Helgen pers. comm. 2006).

Conservation Actions [top]

Conservation Actions: The species occurs in a number of protected areas.
