The Pygmy Fruit Bat (Aethalops alecto), also known as the Grey Fruit Bat, is a species of megabat.


Three specimens were collected in April 1995 from Bario highlands in Sarawak. A. alecto is confined to montane forest above 1000 m from Peninsular Malaysia, Sumatra and Java. In Borneo it had been recorded at Mount Kinabalu and Crocker Range in Sabah; Gunung Mulu and Bareo in Sarawak (Payne et al. 1985 ).

Biology and ecology[edit]

Two adult females and an adult male collected from Bario were in a non-reproductive condition. Kitchener et al. (1990) reported a pregnant female collected on Lombok Island in October. Hill (1961) observed pregnancy in February and May in Peninsular Malaysia. Medway (1978) recorded that the months between February to June was the breeding period for the species. This species appears to be confined to montane forest above 1,000 m (Payne et al. 1985).

External measurements[edit]

  • 3 samples. FA = 43.70-48.00, TL = none, EL = 10.00-12.00, TB = 15.30-17.00, WT = 12.00-18.00.

Measurements are referenced from Diaz.[2] Measurements are without scale, but can only be millimeters. FA = Forearm Length, TL = Tail Length, EL = Ear Length, HFL = Hind Foot Length, TB is not described, and WT = usually W, is weight in grams.

Further measurements are referenced according to Barquez.[3] Measurements are referenced as GLS = Greater Length of Skull, Condylobasal Length (CBL), Least Interorbital Breadth (LIB), Zygomatic Breadth (ZB), Postorbital Constriction (PC), Breadth of Braincase (BB), Length of Maxillary Toothrow (LMxT), Palatial Length (PL), Mastoid Breadth (MB), Length of Mandibular Toothrow (LMdT), Length of Mandible (LM), Width across Upper Canines (CC), and Width across Upper Molars (MM).
