The Yinpterochiroptera, or Pteropodiformes, is a suborder of the Chiroptera, which includes taxa formerly known as megabats and five of the microbat families: Rhinopomatidae, Rhinolophidae, Hipposideridae, Craseonycteridae, and Megadermatidae. This suborder is primarily based on molecular genetics data. This proposal challenged the traditional view that megabats and microbats form monophyletic groups of bats. 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). Recent studies using transcriptome data have found strong support for the Yinpterochiroptera-Yangochiroptera classification system. Researchers have created a relaxed molecular clock that estimates the divergence between Yinpterochiroptera and Yangochiroptera around 63 million years ago. The most recent common ancestor of Yinpterochiroptera, corresponding to the split between Rhinolophoidea and Pteropodidae (Old World Fruit bats), is estimated to have occurred 60 million years ago.
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, some researchers use the terms Pteropodiformes and Vespertilioniformes. Under this new proposed nomenclature, Pteropodiformes is the suborder that would replace Yinpterochiroptera.

The proposed suborder Yinpterochiroptera is based on the conjunction of ‘yin’ and ‘ptero’ to reflect the composition of this new taxon.

Following the recommendations of Hutcheon and Kirsch (2004), we refer to the two suborders of chiropterans as ‘Pteropodiformes’ (comprising the Pteropodidae, Rhinolophidae, Hipposideridae, Megadermatidae, and Rhinopomatidae) and ‘Vespertilioniformes’ (remaining microbat families).
