The Staphylinidae is an extremely large family of usually small, gracile beetles with a flexible abdomen. Many staphylinids have reduced elytra that expose the greater part of a long, flexible abdomen, but there are notable exceptions. Some subfamilies, such as Scydmaeninae and many Omaliinae, have most or all of the abdomen covered by the elytra. Molecular phylogenetic analyses also indicate that some other groups with complete elytra classified to date in separate families, such as the Silphidae, may also be derived from within the Staphylinidae (McKenna et al. 2015). Staphylinids with complete elytra can usually be distinguished from other beetles by the presence of six visible abdominal ventrites and the lack of lobes on the fourth tarsomeres (Newton et al. 2001). Ocelli are commonly absent but are present in some subfamilies such as Omaliinae.
The majority of staphylinids are predatory, but a number of species feed on carrion, algae or fungi (Grimaldi & Engel 2005). Some, such as a number of members of the Aleocharinae and Pselaphinae, are specialised inquilines of social insects. They may have a flattened, limuloid body form that possibly provides physical protection from their hosts, or they may have a physogastric abdomen and/or exudatory trichomes that gives them a physical or chemical resemblance to the host insects (Seevers 1957). Some staphylinids are subsocial with adults caring for larvae in nests or burrows (Newton et al. 2001).
Subgroups of the Staphylinidae include the Apateticinae which have elytra covering most of the abdomen, lobed tarsomeres and gradually clavate antennae. The Habrocerinae have a very compact, shining body with few large setae and extremely slender, verticillate antennae. The genus Trichophya has similar antennae to the Habrocerinae but the body is more densely punctate and setose. The Trigonurinae are a Holarctic subfamily with a compact body form and relatively long elytra that extend past the thorax and leave only five tergites exposed. Micropeplinae have nine-segmented antennae with the last forming a large club (Newton et al. 2001).
