Cucujoidea is a superfamily of beetles. This group formerly included all of the families now included in the superfamily Coccinelloidea. They include some fungus beetles and a diversity of lineages of "bark beetles" unrelated to the "true" bark beetles (Scolytinae), which are weevils.
Corylophidae is a family of minute hooded beetles, sometimes called minute fungus beetles, in the superfamily Coccinelloidea. There are about 18 genera and at least 120 described species in Corylophidae. They feed on microfungi such as molds, and are often found associated with bark, as well as in leaf litter and other decaying vegetation. In older literature, the family name was often given as Orthoperidae.
Erotylidae, or the pleasing fungus beetles, is a family of beetles belonging to Cucujoidea containing over 100 genera. In the present circumscription, it contains 6 tribes and 10 subfamilies. In other words, the narrowly circumscribed Erotylidae correspond to the subfamily Erotylinae in the definition sensu lato. There are doubts on the monophyly of lower ranked taxa within Erotylidae, with further phylogenetic studies requiring better sampling and studies of unexplored character sets, for example the metendosternite and penile flagellum, which are generally lacking detailed morphological studies within the Coleoptera literature. The Eroytlina taxonomy is based on traits such as their different colors and not off morphological differences like mouthparts, thorax, and abdominal terminalia (Pecci-Maddalena).
Chaetosomatidae is a small family of beetles, in the superfamily Cleroidea. There are three extant genera, two of which are endemic to New Zealand with the other (Malgassochaetus) native to Madagascar. Members of this family are predaceous on wood-boring insects.
Boganiidae is a family of beetles, in the superfamily Cucujoidea. Members of the family are found in southern Africa, Australia and New Caledonia. Adults and larvae are pollenivorous, feeding on the pollen of cycads and flowering plants of the families Myrtaceae, Meliaceae, Cunoniaceae and Elaeocarpaceae. Metacucujus and Paracucujus act as pollinators for cycads Encephalartos and Macrozamia respectively. This association with cycads goes back to at least the Mid-Cretaceous, with an extinct form being found with preserved cycad pollen in 99 million year old Burmese amber.
Cavognathidae is a family of beetles, in the superfamily Cucujoidea. It contains a single genus, Taphropiestes with around a dozen species known from South America, Australia and New Zealand. In Australian and New Zealand species adults and larvae have been found living in bird nests, but their ecology is unclear, but they are possibly scavengers.
Hobartiidae is a family of beetles, in the superfamily Cucujoidea. There are only two known genera Hobartius and Hydnobioides, with six species, five of which are native to Australia, and one species of Hobartius native to Chile and Argentina in South America. Members of the family are mycophagous, living in rotten, fungus infested logs of Araucaria, Nothofagus, and Eucalyptus, where they feed on the fruiting bodies of basidiomycetes.
Laemophloeidae, "lined flat bark beetles," is a family in the superfamily Cucujoidea characterized by predominantly dorso-ventrally compressed bodies, head and pronotal discs bordered by ridges or grooves, and inverted male genitalia. Size range of adults is 1–5 mm (0.04–0.2 in) in length. Currently, it contains 40 genera and about 450 species, and is represented on all continents except Antarctica; species richness is greatest in the tropics.
Byturidae, also known as fruitworms, are small family of cleroid beetles with over 15 described species, primarily distributed in the Holarctic and Southeast Asia. The larvae of at least some genera feed on fruit, such as Byturus, a notable commercial pest of Rubus consuming both the fruit and seeds, while others like Xerasia are associated with catkins. The adults are known to feed on developing leaves, flowers and pollen.
Helotidae is a family of beetles, in the suborder Polyphaga. The family includes about five extant genera, Helota MacLeay, Neohelota Ohta, Afrohelotina Kirejtshuk, Metahelotella Kirejtshuk, and Strophohelota Kirejtshuk. Helotidae are found mainly in the Old World tropics and are absent from Australia and Madagascar. The antennae are clubbed on the final three segments and is retractable within grooves under the head. The wings have reduced venation with just 4 anal veins. Helotids are known to be associated with sap, fruit and flowers, and the larvae of some species are known to bore into wood in order to pupate.
Protocucujidae is a family of beetles, in the superfamily Cucujoidea. It has a single known genus, Ericmodes. Species of Ericmodes are native to southern South America and Eastern Australia. Little is known of their biology, though adults and larvae probably live on vegetation, with adults having also been found in leaf litter and in flight.
Hymaea is a genus of beetles in the family Phloeostichidae.
Monotomidae is a family of beetles in the superfamily Cucujoidea. The family is found worldwide, with approximately 240 species in 33 genera. The ecological habits of the family are diverse, with different members of the group being found under tree bark, in decaying vegetation, on flowers and in ant nests. Their ecology is obscure, while at least some species are mycophagous, feeding on the fruiting bodies of ascomycete fungi, Rhyzophagus are predators on bark beetles and possibly Phoridae larvae, with the larvae of some species also being mycophagous.
Acanthocnemus nigricans is a species of cleroid beetle, the only species in the genus Acanthocnemus and the family Acanthocnemidae. Originally native to Australia, the species has spread in modern times to numerous parts of the world, including Europe, Africa, India and Southeast Asia. The insects are pyrophilous, congregating around areas of recently burned wood, being attracted to chemicals found in wood smoke. They have specialised infrared receptors located on the thorax close to the head, used to detect heat. Their life cycle is poorly understood, though mating and egg-laying likely occurs within ash. The larvae are possibly saprophagous.
Xenoscelinae is a subfamily of pleasing fungus beetles in the family Erotylidae. There are about 8 genera and 12 described species in Xenoscelinae.
Derolathrus is a genus of Jacobson's beetles in the family Jacobsoniidae. There are 11 described species in Derolathrus.
Agapytho is the only genus of beetles in the family Agapythidae. The genus contains a single species, Agapytho foveicollis, which is endemic to New Zealand. Larvae and adults are found on sooty mold growing on Nothofagus trees. Gut contents indicate that at least adult Agapytho consume the sooty mould as part of their diet.
Myrabolia is the only genus in the beetle family Myraboliidae in the superfamily Cucujoidea. It has about 13 species, found in Australia. Adults and possibly larvae live under the bark of Eucalyptus trees.
Priasilphidae is a family of beetles in the superfamily Cucujoidea. They have a Gondwanan distribution, with the three known genera Chileosilpha, Priasilpha and Priastichus being native to Chile, New Zealand and Tasmania respectively. Most species are flightless, lacking wings. Priasilphids inhabit decaying wood and moss in forest habitats. They are likely mycophagous, feeding on fungi.
