Bolboceratidae, the dor beetles, is a family of beetle. It was historically treated as a subfamily of the earth-boring dung beetles (family Geotrupidae), but has been considered a separate family since 1995. Some recent classifications have persisted in treating bolboceratids as a subfamily (e.g.) but these classifications are contradicted by recent phylogenetic studies of relationships indicating that bolboceratids are not closely related to geotrupids (e.g., that bolboceratids are more closely related to Pleocomidae and Passalidae).
Boganiidae is a family of beetles, in the suborder Polyphaga.Bolbelasmus
Bolbelasmus is a genus of beetles in the family Geotrupidae. There are at least 20 described species in Bolbelasmus.Bolbocerosoma
Bolbocerosoma (sometimes misspelled as Bolbocerasoma) is a genus of earth-boring scarab beetles in the family Bolboceratidae. There are about 13 described species in Bolbocerosoma.Bolbocerosoma pusillum
Bolbocerosoma pusillum is a species of beetle in the family Bolboceratidae. It is found in North America.Callirhipidae
Callirhipidae is a family of beetles in the superfamily Byrrhoidea. It was described by Emden in 1924.Cavognathidae
Cavognathidae is a family of beetles, in the suborder Polyphaga.Discolomatidae
Discolomatidae is a family of beetles, in the suborder Polyphaga.Geotrupidae
Geotrupidae (from Greek geos, earth, and trypetes, borer) is a family of beetles in the order Coleoptera. They are commonly called earth-boring dung beetles. Most excavate burrows in which to lay their eggs. They are typically detritivores, provisioning their nests with leaf litter (often moldy), but are occasionally coprophagous, similar to dung beetles. The eggs are laid in or upon the provision mass and buried, and the developing larvae feed upon the provisions. The burrows of some species can exceed 2 metres in depth.
A few species communicate by stridulation (rubbing body parts together to make sounds).Histeroidea
Histeroidea is a superfamily of beetles in the infraorder Staphyliniformia.Hobartiidae
Hobartiidae is a family of beetles, in the suborder Polyphaga.Lamingtoniidae
Lamingtoniidae is a very small family of beetles, in the suborder Polyphaga. It contains the single genus Lamingtonium and the single species Lamingtonium binnaberrense.Ochodaeidae
Ochodaeidae, also known as the sand-loving scarab beetles, is a small family of scarabaeiform beetles occurring in many parts of the world.These beetles are small, ranging from 3–10 millimetres (0.12–0.39 in). Their bodies are elongate and convex, with black and brown colors including yellowish- and reddish-brown shades.As of 2012, the biology and habits of Ochodaeidae beetles is still mostly unknown. Most types have been collected in sandy areas at night, while some of their species are active during the day.Odonteus
Odonteus is a genus of beetles in the family Bolboceratidae, formerly known by the name Bolboceras. The name Bolboceras was replaced in 1990 when it was discovered that Odonteus had been published one month earlier; this finding was upheld by ICZN Opinion 2138 in 2006, which made the two names synonymous, with Odonteus having priority. Some researchers continue to use the invalid junior name (e.g.).Odonteus obesus
Odonteus obesus is a species of earth-boring scarab beetle in the family Bolboceratidae. It is found in North America.Orsodacnidae
The Orsodacnidae are a small family of leaf beetles, previously included as a subfamily within the Chrysomelidae. It is the smallest of the Chrysomeloid families in North America; Oxypeltidae is smaller, with only three species in South America.Perimylopidae
Perimylopidae is a family of beetles, in the large suborder Polyphaga. It is now called PromecheilidaeProtocucujidae
Protocucujidae is a family of beetles, in the suborder Polyphaga.Pterogeniidae
Pterogeniidae is a family of beetles, in the large suborder Polyphaga.Synchroidae
The Synchroidae are a small family of beetles with no vernacular common name, though recent authors have coined the name synchroa bark beetles. The family consists of three extant genera, Mallodrya, Synchroa, and Synchroina, with a total of nine species.
