Craseonycteridae Hipposideridae Pteropodidae Rhinopomatidae Rhinolophidae Megadermatidae 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 proposal challenged the traditional view that megabats and microbats form monophyletic groups of bats.

Recent studies using transcriptome data have found strong support for the Yinpterochiroptera-Yangochiroptera classification system.

[3] 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.
