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 [1]

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. The largest measure just 3 millimeters long, while some very small species only reach 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.

Clidicus (beetle)

Clidicus is a rove beetle genus in the family Staphylinidae.

Ektatotricha

Ektatotricha is an extinct, monotypic, genus of ant-like stone beetle in the family Staphylinidae containing the single species Ektatotricha paradoxa.The genus is known from a total of 15 specimens in amber from amber deposits near Tanai Village 105 kilometres (65 mi) northwest of Myitkyina in the Kachin region of Myanmar. Burmese amber has been radiometrically dated using U-Pb isotopes, yielding an age of approximately 99 million years old, close to the Aptian – Cenomanian boundary. The holotype, a single, complete adult with specimen number "AMNH Bu-1464", and six of the paratypes are now deposited in the American Museum of Natural History. Four more of the paratypes are deposited in the University of Kansas Natural History Museum collections in Lawrence, Kansas, USA. The remaining two paratype specimens are currently in a private collection, but are to be deposited in the Field Museum of Natural History, Chicago. In addition to the holotype and 12 paratypes, two other American Museum of Natural History specimens were examined as part of the study; however, they were not designated as type material.

Electroatopos

Electroatopos castaneus is an extinct species of ant-like stone beetle, described in 2010, and the only species in the genus Electroatopos. It existed in what is now Myanmar during the Middle Cretaceous period.

Kachinus

Kachinus is an extinct genus of ant-like stone beetle in the family Staphylinidae containing the single species Kachinus antennatus.

List of beetles of Ireland

There are over 2,154 species of beetles species of Coleoptera native to Ireland. These are disposed in 84 families. By contrast there are 4,034 species of Coleoptera in the British Isles, consisting of 106 families . The largest beetle families in Ireland are the rove beetles (Staphylinidae) with 641 species, the weevils (Curculionidae) with 214 species, and the ground beetles (Carabidae) with 210 species.

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.
