Staphylinidae
The rove beetles are a family (biology), family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) 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. One well-known species is the devil's coach-horse beetle (''Ocypus olens''). For some other species, see List of rove beetle (Staphylinidae) species recorded in Britain, list of British rove beetles.

Megalopsidiinae
''Megalopinus'' is the only genus in the subfamily Megalopsidiinae of the Rove beetle, Staphylinidae. 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. Four species are found in North America: ''Megalopinus caelatus'' (Gravenhorst, 1802), ''Megalopinus punctatus'' (Erichson, 1840), ''Megalopinus rufipes'' (LeConte, 1863) and Megalopinus lingafelteriMainda 2023. So far, more than 430 species are known from the entire New World. From the Orientalis 74 (+ one fossil, ''Megalopinus extinctus'' Yamamoto & Solodovnikov, 2016, described from Burmese amber) species are known.

Aleocharinae
The Aleocharinae are one of the largest subfamilies of rove beetles, containing over 12,000 species. Previously subject to large-scale debate whether the subfamily deserved the familial status, it is now considered one of the largest subfamilies of rove beetles.James S. Ashe (1947–2005Tree of lifeUniversity of Kansas, Lawrence, Kansas, USA Description The Aleocharinae are generally small to minute beetles, as they can reach a maximum length of about , but usually they are long, with a few species of , among the smallest of beetles. The body is usually slender, often densely and finely punctured; the head is more or less round and the color may be light or dark brown, reddish-brown, or black, sometimes with contrasting colors of red, yellow, and black. Anatomy Because of the size of the subfamily, their anatomy is extremely variable. However, a few key features are shared by all rove beetles. All members have antennae with 10 or 11 segments. The antennal insertion is poster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pselaphinae
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. This is a species-rich subfamily with 9,000 to 10,000 described species. They are especially diverse in the tropics. They are commonly found in decaying leaf litter on forest floors, in grass tussocks, flood refuse, moss, and other highly structured and particulate microhabitats. Little is known about their biology. They are believed to be predatory on small invertebrates, in particular springtails (order Collembola) and oribatid mites (order Oribatida). Pselaphines have attracted the interest of entomologists due to their exquisite and variable morphology, which is rewarding to observe with a microscope. In addition, the myrmecophilous ("ant-loving") behavior of some pselaphine groups (notably ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paederinae

Scydmaeninae
Scydmaeninae are a subfamily of small beetles, commonly called ant-like stone beetles or scydmaenines. These beetles occur worldwide, and the subfamily includes some 4,500 species in about 80 genera. Established as a family, they were reduced in status to a subfamily of Staphylinidae in 2009 Many scydmaenine species have a narrowing between head and thorax and thorax and abdomen, resulting in a passing resemblance to ants that inspires their common name. They are typically small beetles, with some very small species only half a millimeter in length. Scydmaenids typically live in leaf litter and rotting logs in forests, preferring moist habitats. A number of types are known to feed on oribatid mites, using "hole scraping" and "cutting" techniques to get through the mite's hard shells. In addition to the two living subfamilies, the prehistoric subfamily Hapsomelinae, known only from fossils, has been placed here. Taxonomy Supertribes * Cephenniitae Reitter, 1882 * † Hap ...
