The Omaliinae are a subfamily of the Staphylinidae, rove beetles.[1]

Anatomy[edit]

Typical adults are 1.5 to 6 mm long, somewhat broader in shape than are most Staphylinidae, with somewhat longer elytra (without serial punctures), the head with a broad neck, the antennae which are only slightly broader at the apex, and tarsi of five articles. In almost all genera is a pair of ocelli near the base of the head, and in a few, the elytra cover the entire abdomen. The maxillary mala of larvae is strap-shaped, but not as long as in the Proteininae, and the mandible lacks a prostheca.

Ecology[edit]

Adults and larvae occur in leaf litter, decaying fruits, moss, and under bark of dead trees. Adults of several species and larvae of a few occur in flowers. Adults and larvae of many genera and species are believed to be predatory (they feed on freshly killed small insects), though a few seem to be phytophagous (they damage flowers) or saprophagous (they feed on decaying fruits).

Systematics and evolution[edit]

The Omaliinae subfamily is large (comprising over 100 genera), and is divided into these seven tribes:

In North America, 55 genera and more than 200 species are found.
