How to Identify Emballonuridae

Key Identification Features

• Microbial fermentation inside the wing sac may produce distinct, identifiable scent signals.
• This feature distinguishes Cormura brevirostris from all other sac-winged bats, which typically have their sacs positioned much closer to the body.
• The lesser white-lined bat has a distinctive odiferous gland on the distal part of its arm that opens to the dorsal section of the wing, and this opening is larger in males than in females.
