Thoopterus nigrescens


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Thoopterus nigrescens
Species Authority: (Gray, 1870)
Common Name(s):
English Swift Fruit Bat
Taxonomic Notes: A second, undescribed species of Thoopterus occurs at higher altitudes in north, central and southwest Sulawesi. A third, undescribed species occupies the island of Mangole in the Sula Islands. The Morotai record may be based on a mislabelled specimen from northern Sulawesi. According to L. Ruedas (pers. comm.) molecular data suggest a north-south species level split in Sulawesi rather than a high elevation-low elevation dichotomy as described above.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Ruedas, L., Kingston, T., Helgen, K. & Sinaga, J.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority), Chanson, J. & Chiozza, F. (Global Mammal Assessment Team)
Listed as Least Concern because its extent of occurrence is greater than 20,000 km², it is very common, and its populations are not declining fast enough for listing in a more threatened category.

Geographic Range [top]

Range Description: This species occurs throughout Sulawesi and on the adjacent islands of Buton, Mangole, the Talaud and Sangihe island groups, and probably Morotai, all in Indonesia. Specimens have also been collected from Wowoni (U. Sinaga pers. comm.).
