Laemophloeus sp., copyright Robert Webster.

Belongs within: Cucujoidea.

The Laemophloeidae are a group of elongate-bodied beetles that mostly feed on moulds and other fungi. They may be recognised by the presence of a pair of longitudinal, submarginal carinae on the pronotum. The species Laemophloeus ferrugineus is a cosmopolitan stored food pest (Britton 1970).

Characters (from Lawrence & Britton 1991): Elongate, parallel-sided, usually flattened, glabrous or pubescent; head large, prognathous, with prominent mandibles; antenna eleven-segmented, club (if present) never very large or abrupt, scape may be modified in male; pronotum bearing pair of longitudinal, submarginal carinae; fore coxae globular, trochantins concealed, fore coxal cavities externally open or closed, internally closed; elytra often carinate; mid coxal cavities widely separated, laterally open; tarsal formula 5-5-5 or 5-5-4; abdomen with five ventrites, none connate. Larvae narrowly elongate, parallel sided, flattened and lightly sclerotised, except for head, 8th segment and T9. Head flattened, with moderately long antennae, paired dorsal endocarinae and long, parallel hypostomal rods; mandible with several hyaline processes near base of mesal edge; mala blunt; T9 forming articulated plate, S9 and segment 10 reduced and concealed within emargination in S8.
