Status and Conservation. Classified as Least Concern on The IUCN Red List. There is very little information on population status of the Lesser Naked Bat, but deforestation is occurring throughout its distribution. It is hunted for consumption in Sulawesi.

Descriptive notes. Head-body 104 - 5 - 115 - 4 mm, tail 54 - 3 - 64 - 1 mm, ear 24 - 1 - 29 mm, hindfoot (without claw) 21 - 23 mm, forearm 69 - 478 mm; weight 73 - 100 g. Body of the Lesser Naked Bat appears naked but is covered in very fine short hairs, particularly on undersides. Skin is dark brown to dark gray, and although smooth dorsally, there are thick loose folds on underside, particularly near genitals. There is a patch of stiff hairs or bristles associated with gular pouch, in which there is glandular structure, and bristles of short stiff hairs with spatulated ends on hallux of hindfeet, presumably used for grooming. Ears are not joined over top of head and are oriented laterally and slightly forward. Skull is broad, with well-developed sagittal crest and powerfuljaws. Lips are smooth, and upperlips appear to project over lowerlips to present an “ overbite. ” Wings are long, narrow, and folded when an individual is at rest such that third and fourth phalanges are tucked into subaxillary pouches formed by attachment of plagiopatagium dorsally rather than laterally; attachment runs from upper arm to thigh. Pouches open posteriorly, and tensor plagiopatagia muscle can tighten opening to stabilize position of folded wing. When wings are folded, an individual can move quadrupedally using pad at base of thumb and hindlimbs. Sturdy hindlimbs are angled such that feet project laterally, wings can be folded, and phalanges tucked away, and thumbs have thickened pads. Calcar might play a role in supporting shank for quadrupedal motion. Hallux of hindfootis set at almost a right angle to the rest of digits, appearing opposable and creating hand-like appearance from which the genus got its name (Greek for badger hand); this might assist with tucking wingtips into the pouch, terrestrial locomotion, moving backward up trees, and arboreal locomotion. Reverse climbing behavior is known for the related and morphologically very similar Greater Naked Bat (C. torquatus). Hindlimbs are short, stocky, and very strong; shank is angled anterodorsally, supporting quadrupedal movements (walking on “ all fours ”) and climbing. M? has third ridge highly reduced. Dental formulas 1 / 1, C 1 / 1, P 1 / 2, M 3 / 3 (x 2) = 26.
