See text Yangochiroptera, or Vespertilioniformes, is a suborder of Chiroptera that includes most of the microbat families, except the Rhinopomatidae, Rhinolophidae, Hipposideridae, Craseonycteridae and Megadermatidae.

All bats in Yangochiroptera use laryngeal echolocation (LE), which involves the use of high-frequency sounds to detect prey and avoid obstacles.

The Yangochiroptera/ Yinpterochiroptera classification remains a relatively recent proposal, which challenges the traditional view that megabats and microbats form monophyletic groups by claiming that the superfamily Rhinolophoidea is more closely related to Old World fruit bats than other microbats.

[2] Further studies are being conducted, using both molecular and morphological cladistic methodology, to assess the merit of this alternative view of bat evolution.

[4] As an alternative to the subordinal names Yinpterochiroptera and Yangochiroptera, some researchers use the terms Pteropodiformes and Vespertilioniformes.
