Zopherinae
ironclad beetles
Zopherinae is a subfamily of beetles commonly known as ironclad beetles, characterized by exceptionally hardened exoskeletons. The subfamily currently contains eight genera across two tribes: seven genera in Zopherini and the monotypic genus Phellopsis in its own tribe Phellopsini. Historically treated as a family alongside Usechinae, Zopherinae is now classified within the expanded family Zopheridae. These beetles are primarily associated with rotting wood and are known to be fungivores.
