Megalopsidiinae

The Megalopsidiinae are a subfamily of the Staphylinidae, rove beetles.[1] They have large eyes, antennae with distinct di- or trisegmented clubs. The tarsal formula is 5-5-5. They have unique elongated processes at theanterior margin of the labrum. They are found in decaying trees and fungus-infested logs. In North America, one genus and two species: Megalopinus caelatus (Gravenhorst) and M. rufipes (LeConte) are known.
