Rousettus aegyptiacus arabicus Anderson and de Winton, 1902
The medium-sized robust fruit bat is found, averaging larger than its cousin R. leschenaultii, southern Pakistan in South Asia. The forearm length averages 88.2 mm (83-90 mm). Muzzle relatively heavy and deep. Ears are simple in form, with weakly developed antitragal lobe. Wings are large, membranes grey in color, the first digit possessing a large claw and the second digit bears smaller claw. A short tail is present. Pelage soft, fine and silky, fulvous brown on the crown, back, flanks and throat, belly grayish. Pelage lighter than R. leschenaultii. Specimens from the Pakistan, R. a. arabicus, shorter and slender muzzle and shorter wings, compared to the nominate form, R. a. aegyptaicus.
This species can be separated from R. leschenaultii basing on: 1. Hindfeet large (20.0-25.0 mm vs. 15.0-22.0 mm), 2. Thumbs (first digit comprised of metacarpal, phalanx and claw) large (30.0-33.4 mm vs. 24.4-31.1 mm), and 3. Longer second phalanx of the third digit (51.9-56.3 mm vs. 39.6-46.2 mm).
Common species encountered in a variety of habitats in South Asia from arid deserts to humid forests. Colonial species, lives in colonies ranging from a few individuals to 40 in subterranean caves, underground irrigation tunnels, open wells, deserted buildings and forts. Individuals leave their roosts shortly after sunset and fly to feed on flowers, leaves and fruits of a vast variety of plants including dates. This species breeds once a year, single pup to each female.
