Descriptive notes. Head-body c.45 47 mm, tail 35-37 mm, ear 13-14 mm, hindfoot 6-7 mm, forearm 32:6-36- 6 mm; weight ¢. 5 g. Fur is silky and medium in length (dorsal fur 4-6 mm; ventral fur 3-4 mm). Ventral hairs are strongly bicolored, with dark brown bases and yellowish tips. Dark brown bases and medium brown tips of dorsal fur contrast weakly. Ears are comparatively short, extending forward halfway from eye to nostril. Antitragal notch is barely evident. Membranes are mummy brown; plagiopatagium is attached to foot toes by a broad band of membrane. Skull is mediums-sized (greatest length of skull 13-4-14- 9 mm); occipital region is rounded;sagittal crest is generally absent, or when present,it is low; and lambdoidal crests are generally present and range from low to medium. P? is aligned in tooth row and visible in labial view. Wing morphology is typical of aerial insectivore that uses cluttered spaces.
Habitat. Well-preserved forests, with large trees, caves, gullies, and rocky outcrops; escarpment covered in a mahogany forest; riparian areas with little water flow but numerous freshwater pools along riverbed; dense Acacia (Fabaceae) shrubland; and anthropogenic habitats at elevations of 50-300 m.
