Mycetophagidae

Mycetophagus quadriguttatus, copyright Pierre Bornand.

Belongs within: Tenebrionoidea.

The Mycetophagidae are a group of beetles that may be found as adults or larvae in rotting wood or in association with fungal fruiting bodies (Lawrence & Britton 1991). The genus Berginus has a head nearly as wide across the eyes as the pronotum, and a two-segmented antennal club, whereas other genera in the Mycetophaginae have the head distinctly narrower than the pronotum and the antennal club (if present) comprises more segments (Young 2002).

Characters (from Lawrence & Britton 1991): Oblong to ovate, somewhat flattened beetles, uniformly brown or with yellow maculae on elytra, densely pubescent. Antennae 11-segmented with three- or four-segmented club; eyes relatively large, coarsely faceted; frontoclypeal suture present or absent; fore coxae transverse, trochantins exposed or concealed, coxal cavities externally open, internally closed; mid coxal cavities contiguous or narrowly separated, laterally open; tibial spurs often well developed and serrate; fore tarsi modified in male, tarsal formula 4-4-4 in female, 3-4-4 in male; abdomen with five ventrites, all free. Larvae elongate and parallel sided, slightly flattened and moderately sclerotised dorsally, with well-developed legs and slightly curved, simple urogomphi, which are more or less approximate at base.
