Aethalops (Meaning: sooty bat) is a genus of in the family Pteropodidae. It contains two species:
-
Borneo fruit bat, A. aequalis
-
Pygmy fruit bat, A. alecto
Taxonomy
Aethalops was described as a new genus in 1923 by British mammalogist
Oldfield Thomas.
Thomas named the genus
Aethalodes, though that name was already in use for a genus of beetle.
Thomas then suggested the name
Aethalops in a subsequent publication to remedy the problem.
The type species for the genus was the pygmy fruit bat,
Aethalops alecto, which had been collected in
Sumatra by Lambertus Johannes Toxopeus.
In 1938, the genus gained its second species, the Borneo fruit bat, A. aequalis.
This species was described by American zoologist Glover Morrill Allen.
The holotype was collected in 1937 in Mount Kinabalu, Malaysia, which is on the island of Borneo.
It was collected by J. Augustus Griswold, Jr. while on the Harvard Primate Expedition led by Harold Jefferson Coolidge Jr.
The genus has been revised over the years, with some authors considering it Monotypic taxon, or only containing one species.
The Borneo fruit bat has, at times, been considered a synonym of the pygmy fruit bat.
As of 2019, the prevailing consensus is that the genus does, in fact, contain two species.
