Biology:Megalopinus
Megalopinus is the only genus in the subfamily Megalopsidiinae of the Staphylinidae.[1] Species in this genus have large eyes, antennae with distinct di- or trisegmented clubs. The tarsal formula is 5-5-5. They have unique elongated processes at the anterior margin of the labrum. They are found in decaying trees and fungus-infested logs.[2] Four species are found in North America: Megalopinus caelatus (Gravenhorst, 1802), Megalopinus punctatus (Erichson, 1840), Megalopinus rufipes (LeConte, 1863) and Megalopinus lingafelteri Mainda, 2023.
So far, more than 430 species are known from the entire New World.[3][4] From the Orientalis 74 (+ one fossil, Megalopinus extinctus Yamamoto & Solodovnikov, 2016, described from Burmese amber[5]) species are known.[6]
