Cryptophagidae

Belongs within: Cucujoidea.Contains: Atomaria. The Cryptophagidae are small beetles that feed on mould and other fungi under bark and in leaf litter. Some cryptophagids may also be found in stored foodstuffs. The North American species Antherophagus convexulus may be found on flowers where they attach themselves to visiting bumblebees in order to be transported back… Continue reading Cryptophagidae

Nitidulidae

Belongs within: Cucujoidea.Contains: Meligethes, Kateretidae, Nitidulinae, Cillaeinae, Carpophilus. The Nitidulidae are a morphologically and ecologically diverse group of small beetles, many of which feed on fungi but which may also feed on live or decaying vegetation. They may be distinguished by the combination of a three-segmented antennal club, five-segmented tarsi with dilated tarsomeres and a… Continue reading Nitidulidae

Erotylinae

Belongs within: Cucujoidea.Contains: Tritomini. The Erotylinae are a clade of beetles associated with fungi, usually macroscopic Basidiomycetes (Leschen 2003). Many species are brightly coloured and produce distasteful defensive chemicals from pores and joints on the body (Bouchard 2014). The antennal insertions are visible from above in members of tribes Dacnini, Megalodacnini and Tritomini but concealed… Continue reading Erotylinae

Languriinae

Belongs within: Cucujoidea. The Languriinae are a predominantly phytophagous group of beetles whose larvae are often stem borers. Subgroups include the Languriini, characterised by falcate mandibles and well-exposed antennal insertions (Leschen 2003). Characters (from Leschen 2003): Subapical serrations of mandible absent; lacinia usually with three lacinial spines (occasionally two); lateral pockets absent on mentum; medial… Continue reading Languriinae

Phalacridae

Belongs within: Cucujoidea. The Phalacridae are a group of ovate, strongly convex beetles that mostly feed on fungal spores (Lawrence & Britton 1991). Members of the genus Olibrus feed on pollen and visit flower heads of Asteraceae (Steiner 2002). Characters (from Lawrence & Britton 1991): Broadly ovate, strongly convex, glabrous and shining beetles, lateral portions… Continue reading Phalacridae

The Silvanidae are a group of elongate, more or less flattened beetles found living in leaf litter and under bark; several species are widely distributed as storage pests. Characters (from Lawrence & Britton 1991): Elongate, parallel-sided, more or less flattened, pubescent beetles with prognathous head, abruptly constricted posteriorly to form… Continue reading Silvanidae

Monotomidae

Belongs within: Cucujoidea. The Monotomidae are a group of elongate, parallel-sided beetles generally found under wood or in decaying vegetable matter (Bouchard 2014). Characters (from Lawrence & Britton 1991): Elongate, parallel-sided, subcylindrical to flattened, may be glabrous or clothed with decumbent setae, elytra may be truncate, exposing pygidium. Head usually abruptly narrowed posteriorly, forming distinct… Continue reading Monotomidae
