Rhinopomatidae

Mouse-tailed bats are a group of insectivorous bats of the family Rhinopomatidae with only three to five species, all contained in the single genus Rhinopoma. They are found in the Old World, from North Africa to Thailand and Sumatra, in arid and semi-arid regions, roosting in caves, houses and...

Megadermatidae

Megadermatidae, or False Vampire Bats, are a family of bats found from central Africa, eastwards through southern Asia, and into Australia. They are relatively large bats, ranging from 6.5 cm to 14 cm in head-body length. They have large eyes, very large ears and a prominent nose-leaf. They have a...

. This taxon is primarily based on molecular genetics data. This is a relatively recent proposal, which challenges the traditional view that megabats and microbats form monophyletic groups of bat

Bat

Bats are mammals of the order Chiroptera "hand" and pteron "wing") whose forelimbs form webbed wings, making them the only mammals naturally capable of true and sustained flight. By contrast, other mammals said to fly, such as flying squirrels, gliding possums, and colugos, glide rather than fly,...

s. Further studies are being conducted, using both molecular and morphological cladistic methodology, to assess its merit.

The term Yinpterochiroptera is constructed from the words Pteropodidae (the family of megabats) and Yinochiroptera (a term proposed in 1984 by Karl F. Koopman to refer to certain families of microbats).

Apparently the first appearance of the term Yinpterochiroptera was in 2001, in an article by Mark Springer et al.

As an alternative to the subordinal names Yinpterochiroptera and Yangochiroptera

Yangochiroptera

The Yangochiroptera is a proposed suborder of Chiroptera that includes most of the microbat families, except the Rhinopomatidae, Rhinolophidae and the Megadermatidae. These other families, plus the megabats, are seen as part of another suborder, Yinpterochiroptera.The rationale for the...

, some researchers use the terms Pteropodiformes and Vespertilioniformes. Under this new proposed nomenclature, Pteropodiformes is the suborder that would replace Yinpterochiroptera.
