Staphylinidae
The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest extant family of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus ''Leehermania'' proves to be a member of this family. 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. For some other species, see list of British rove beetles. Anatomy As might be expected for such a large family, considerable variation exists among the species. Sizes range from <1 to , with most in the 2–8 mm range, and the form is generally elongated, with some rove beetles being ovoid i ...

Megalopsidiinae
The Megalopsidiinae are a monogeneric subfamily of the Staphylinidae, which includes only the genus '' Megalopinus''. They 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. Three species are found in North America: ''Megalopinus caelatus'' (Gravenhorst, 1802), ''Megalopinus punctatus'' (Erichson, 1840) and ''Megalopinus rufipes'' (LeConte, 1863). So far, 332 species are known from the entire New World.

Dasycerinae
Dasycerinae is a subfamily In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoologi ... of rove beetles. Dasycerinae currently only contains 1 extant genus and 3 extinct genera. Genera There are currently 4 described genera in Dasycerinae: * †'' Cedasyrus'' * '' Dasycerus'' * †'' Protodasycerus'' * †'' Vetudasycerus'' († = extinct) Anatomy They have antennae with 11 segments and trisegmented antennal clubs. The tarsi have three segments, and the elytra cover or nearly cover the entire abdomen. Ecology These beetles inhabit moist broadleaf forest litter.Ferro, M. L., M. L. Gimmel, K. E. Harms, and C. E.

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 (nota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paederinae
The Paederinae are a subfamily of the Staphylinidae, rove beetles. The Paederinae include two tribes, Paederini and Pinophilini. This insect is commonly known as Tomcat. Three of the genera of a subtribe of the Paederini are associated with a skin irritation called ''Paederus'' dermatitis, due to a potent vesicant in their haemolymph. This irritant, pederin Pederin is a vesicant toxic amide with two tetrahydropyran rings, found in the haemolymph of the beetle genus '' Paederus'', including the Nairobi fly, belonging to the family Staphylinidae. It was first characterized by processing 25 million fie ..., is highly toxic, more potent than cobra venom. Thirty-six genera and 436 species are found in North America, generally in damp places, under logs, in caves and ant nests, in litter, or on foliage. Genera include '' Rugilus'' and '' Trisunius''.

Empelinae
The Empelinae are a subfamily of rove beetles ; their biology is virtually unknown. Their anatomy and ecology resemble many rove beetles. Ecology and anatomy The Empelinae are small beetles under 2 mm long. They have 11 antennae with loose trisegmented clubs. Their elytra nearly cover the whole of their abdomen. The tarsi, according to scientists, is 5-5-5. Some scientists theorize this is a result of their secluded habitats - forest leaf litter, fungi, and moss at a stream's edge. This makes collecting the subfamily's species hard. Due to the seclusion of the Empelinae, like many rove beetles, (see Aleocharinae), the subfamily's biology is nearly unknown. Systematics The subfamily is small, with its type genus being monotypic; the only species is ''Empelus brunipennis'', discovered Mannerheim in 1852. One species in the subfamily is restricted to North America. However, it has been very successful there, ranging from southern Alaska to California. References *Herman, L. ...
