Cucujoidea

Dorsal and ventral views of Propalticus specimen, from here.


Belongs within: Coleoptera.
Contains: Monotomidae, Nitidulidae, Xenoscelinae, Pharaxonothinae, Erotylinae, Cryptophilinae, Languriinae, Loberinae, Cucujidae, Cryptophagidae, Silvanidae, Atomaria, Phalacridae, Laemophloeidae.

The Cucujoidea are an assemblage of beetles characterised by the presence of a ring-type (cucujoid) aedeagus in the male and a more or less cylindrical, pygopod-like tenth abdominal segment in the larva. Larvae also usually have a mandible with a prostheca and an often falcate mala, and may have six stemmata (Lawrence & Britton 1991).

Cucujoids include a number of fungus-feeding beetle families such as the Erotylidae and Cryptophagidae. The Erotylidae also include a number of plant-feeding species that were previously treated as a separate family Languriidae (Leschen 2003). The Hobartiidae are a family of oblong, pubescent fungus-feeding beetles found in Australia and South America, closely related to the pollen-feeding Boganiidae of Australia and southern Africa. Members of these latter two families possess dorsal tubercles on the mandible that fit against lateral cavities on the clypeus (Lawrence & Britton 1991). They are also closely related to the palmetto beetles of the genus Smicrips, a Neotropical group of tiny beetles associated with vegetation, particularly with palms (Bouchard 2014). Members of the Sphindidae and Protosphindus are unusual in feeding exclusively on slime moulds of the Myxomycetes (Bouchard 2014).
