Megalopinus is the only genus in the subfamily Megalopsidiinae of the Staphylinidae. [3] 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. [4] 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. [1] [5] From the Orientalis 74 (+ one fossil, Megalopinus extinctus Yamamoto & Solodovnikov, 2016, described from Burmese amber [6] ) species are known. [7]

The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra that typically leave more than half of their abdominal segments exposed. With over 66,000 species in thousands of genera, the group is one of the largest families in the beetle order, and one of the largest families of organisms. It is an ancient group that first appeared during the Middle Jurassic based on definitive records of fossilized rove beetles, with the Late Triassic taxon Leehermania more likely belonging to Myxophaga. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems.

<span class="mw-page-title-main">Pselaphinae</span> Subfamily of beetles

Pselaphinae are a subfamily of beetles in the family Staphylinidae, the rove beetles. The group was originally regarded as a separate family named Pselaphidae. Newton and Thayer (1995) placed them in the Omaliine group of the family Staphylinidae based on shared morphological characters.

Nicrophorini is a tribe of burying beetles or carrion beetles in the subfamily Silphinae. It was formerly treated as subfamily Nicrophorinae within family Silphidae, but this family was found to be nested in family Staphylinidae in phylogenetic analyses and Silphidae was reassigned as a subfamily Staphylinidae.

Omalorphanus is monotypic genus of beetles in the family Staphylinidae, the rove beetles, where it is placed in the subfamily Omaliinae. The only species is Omalorphanus aenigma. The genus and the species were described by John Milton Campbell and Donald S. Chandler in 1987 from the H.J. Andrews Experimental Forest (Oregon) at elevations of 3,500 feet (1,100 m) to 4,000 feet (1,200 m). It was described by them as unusual for its number of unusual morphological features, which made the placement of the species difficult.
