Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Chiroptera Pteropodidae

Scientific Name: Thoopterus nigrescens (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.
