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 ...

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 poste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigonurinae
''Trigonurus'' is a genus of rove beetles in the family Staphylinidae, the only family of the subfamily Trigonurinae. There are about nine described species in ''Trigonurus'', found in the Holarctic. Species These nine species belong to the genus ''Trigonurus'': * ''Trigonurus asiaticus'' Reiche, 1865 * ''Trigonurus bruzasi'' Hatch, 1957 * ''Trigonurus caelatus'' LeConte, 1874 * ''Trigonurus crotchii'' LeConte, 1874 * ''Trigonurus dilaticollis'' VanDyke, 1934 * ''Trigonurus edwardsi'' Sharp, 1875 * ''Trigonurus mellyi'' Mulsant, 1847 * ''Trigonurus rugosus'' Sharp, 1875 * ''Trigonurus sharpi'' Blackwelder, 1941 i c g b Data sources: i = ITIS, c = Catalogue of Life, g = GBIF, b = Bugguide.net References Further reading * * External links * Staphylinidae Articles created by Qbugbot {{staphylinidae-stub ...

Tachyporinae
Tachyporinae is a subfamily of rove beetle. Their common name is crab-like rove beetles. They are generally small, roughly 2.4 to 5 millimeters. There are around 60 species in twelve genera of crab-like rove beetles. All species are fusiform. References {{Taxonbar, from=Q1006615 Beetle subfamilies ...

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, 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 ''Trisunius'' is a genus of rove beetle 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.

Staphylininae
Staphylininae are a subfamily of rove beetles (family Staphylinidae). They contain the typical rove beetles with their long but fairly robust blunt-headed and -tipped bodies and short elytra, as well as some more unusually-shaped lineages. Systematics As it seems, the Staphylininae are part of a large clade together with the subfamilies Euaesthetinae, Leptotyphlinae, Megalopsidiinae, Oxyporinae, Paederinae, Pseudopsinae, Scydmaeninae, Solieriinae, Steninae, and the extinct Protactinae which are only known from fossils. The numerous Staphylininae genera are divided into six tribes, listed below along with some notable genera. However, a scientific study in 2020 proposed moving all tribes except Staphylinini to other subfamilies and raising several of Staphylinini's subtribes to tribal level. This would result in a new total of twelve tribes: Acylophorini, Afroquediini, Amblyopinini, Antimerini, †Baltognathini, Cyrtoquediini, Erichsoniini, Hyptiomini, Indoquediini, Quediini, ...

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