Leperina decorata, from Insects of Tasmania.

Belongs within: Cleroidea.

The Trogossitidae are a morphologically diverse group of predatory or mycophagous beetles, commonly found under bark. Members of the subfamily Egoliinae have a compact, one- or two-segmented antennal club whereas that of Trogossitinae is large, loose and three-segmented (Lawrence & Britton 1991).

Characters (from Lawrence & Britton 1991): Mostly ovate to elongate and more or less flattened, with prognathous head, short antennae bearing large, loose, slightly asymmetrical, 3-segmented club (1- to 2-segmented and compact in Egoliinae), and vestiture of short or long hairs, bristles or scales (Larinotus strongly convex with deflexed head; Egolia subcylindrical and glabrous). Tarsal formula 5-5-5, first segment may be reduced and partly concealed by tibial apex. Abdomen with five ventrites, none connate. Larvae elongate, parallel sided, slightly to strongly flattened, lightly sclerotised, except for head and usually additional sclerites on thorax and T9, mandible usually with 1 or several hyaline processes at base of mesal edge; ventral mouth-parts consolidated, without articulating areas; hypostomal rods usually long and parallel; para-gular sclerites usually present between gula and hypostomal rods; urogomphi usually well developed (minute in Larinotus).
