The family Mycteridae is a small group of tenebrionoid beetles with no vernacular common name, though recent authors have coined the name palm and flower beetles. The family Mycteridae is distributed worldwide. There are about 30 genera and 160 species in three subfamilies Mycterinae, Hemipeplinae and Lacconotinae (=Eurypinae). These 3 subfamilies are extremely diverse in appearance and are sometimes difficult to have a present diagnosis of the adults at the family level. About 20 species are found in Australia, species of three genera are found in North America The larvae are generally flattened and typically inhabit the spaces between leaves or the bases of fronds, where they appear to consume fungi.
The family Pythidae is a small group of tenebrionoid beetles with no vernacular common name, though recent authors have coined the name dead log bark beetles. There are seven genera, which are largely native to the mid-high latitude regions of the Northern Hemisphere and Australia, with one genus also present in the tropical Americas. The larvae are generally found with decaying vegetation and wood on which they feed, while adults are not associated with the larvae and are generally caught using malaise traps and light traps.
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.
Anobiinae is a subfamily of death-watch beetles in the family Ptinidae, with at least 45 genera. It was formerly considered a member of the family Anobiidae, but its family name has since been changed to Ptinidae.
Ennometes is a genus of beetles in the family Callirhipidae. It was described by Pascoe in 1866.
Elmidae, commonly known as riffle beetles, is a family of beetles in the superfamily Byrrhoidea described by John Curtis in 1830. Both adults and larvae are usually aquatic, living under rocks in fast-flowing shallow areas of streams, such as riffles, feeding on algae and biofilms. There are more than 150 genera and 1,500 described species in Elmidae. The oldest record of the group is Cretohypsilara from the Cenomanian aged Burmese amber.
Aegialiinae is a small subfamily of the family Scarabaeidae. Historically the group has been treated as a tribe within a broad definition of the subfamily Aphodiinae.
Scymninae is a subfamily of beetles in the family Coccinellidae. There are at least 170 described species in Scymninae.
Agrilini is a tribe of metallic wood-boring beetles in the family Buprestidae. There are at least 40 described genera in Agrilini.
Ptilodactylidae is a family of beetles belonging to the Elateriformia. There around 500 extant species in 35 genera. They are generally associated with riparian and aquatic habitats. The larvae generally live associated with rotting wood or vegetation, or within gravel and detritus on the edge of water bodies. The larvae of some species feed on submerged rotting wood or on plant roots, while the adults of some species are known to feed on fungus with modified brush-like maxillae.
Throscidae is a family of elateroid beetles found worldwide with around 150 species in 5 extant genera. The larvae are soil-dwelling, siphoning fluid from mycorrhizae attached to trees. The adults are short-lived, with the adult males being noted for a complex mating dance. Like some other elateroids, they are capable of clicking.
Zygaenodini is a tribe of fungus weevils in the family Anthribidae. There are at least 3 genera and 20 described species in Zygaenodini.
Bolboceratinae is a subfamily of earth-boring scarab beetles in the family Geotrupidae. There are about 8 genera and at least 40 described species in Bolboceratinae.
Bostrichini is a tribe of horned powder-post beetles in the family Bostrichidae. There are about 16 genera and at least 150 described species in Bostrichini.
Tropiderini is a tribe of fungus weevils in the family of beetles known as Anthribidae. There are at least two genera and about five described species in Tropiderini.
Conoderinae is a subfamily of true weevils in the beetle family Curculionidae. There are more than 210 genera in 15 tribes, and about 2,400 described species in Conoderinae.
Atomariini is a tribe of silken fungus beetles in the family Cryptophagidae. There are about 5 genera and at least 70 described species in Atomariini.
Choraginae is a subfamily of fungus weevils in the beetle family Anthribidae. There are about 9 genera and more than 180 described species in Choraginae.
Hadrobregmini is a tribe of death-watch beetles in the family Ptinidae. There are at least 3 genera and about 16 described species in Hadrobregmini.
Euceratocerini is a tribe of death-watch beetles in the family Ptinidae. There are at least 4 genera and about 18 described species in Euceratocerini.
