Staphylinidae

Overview

This is the 5th largest family in Australia, and many species remain to be discovered.

Description

Adults usually more or less elongate with truncate elytra that nearly always leave more than half the abdomen exposed; all but first 1 or 2 tergites heavily sclerotised and often flanked by paratergites; abdominal intersegmental membranes usually with pattern of minute sclerites. Larvae always without mandibular mola and usually with articulated urogomphi. In three of the largest subfamilies (Aleocharinae, Paederinae and Staphylininae) the body is rather loosely organised and flexible, and the prothorax has strongly projecting coxae, reduced notal projections, and much exposed membrane. Staphylinid larvae are usually of the active, campodeiform type with well-developed legs, characteristic antennae in which the apex of segment 2 is oblique so that the sensorium arises before the apex, and a pair of articulated urogomphi on T9. A few forms are onisciform, however, and some may have fixed or no urogomphi.
