Emballonuridae
Emballonuridae is a pantropical family, meaning they they are found near the equator worldwide. Two subfamilies are found in the New World, both of which have representatives in Trinidad and Tobago. This family is distinct because the second digit of the forelimb consists of only one metacarpal bone, while two phalanges comprise the third digit. The tail is approximately half the length of the uropatagium (expanse of flight membrane between the hind limbs), but protrudes through the back side of the membrane into a sheath of skin. Most emballonurids have wing sacs; these are often more conspicuous in the males of a species. All species in the Americas have the dental formula of for a total of 32 teeth.

The species Diclidurus albus is the only member of the subfamily Diclidurinae that is present on either Trinidad or Tobago. Diclidurines are differentiated due to their broad clavicles (collarbones), a steep angle where the snout meets the braincase, and a lack of wing sacs. The other five emballonurids found on Trinidad or Tobago are all part of the subfamily Emballonurinae. Emballonurines are distinguished from other subfamilies due to their very narrow clavicles and long, curved postorbital processes (projections of bone near eye sockets). All emballonurines found on Trinidad and Tobago have wing sacs with the exception of Rhynchonycteris naso.
