Lutrochidae is a family of water beetles with a single genus Lutrochus sometimes known as "Travertine beetles". There are around 21 species native to the Americas from the southern United States to Brazil.
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.
Cleroidea is a small superfamily of beetles containing over 10,000 species. Most of the members of the group are somewhat slender, often with fairly soft, flexible elytra, and typically hairy or scaly.
Euderia squamosa is a species of beetles. It is the only member of the monotypic genus Euderia and subfamily Euderiinae.
Trogossitidae, also known as bark-gnawing beetles, are a small family in the superfamily Cleroidea. Many taxa formerly within this family have been removed to other families, such as Lophocateridae, Peltidae, Protopeltidae, Rentoniidae, and Thymalidae. Members of the family are generally predatory and/or feed on fungi, both in adult and larval stages, and are generally associated with wood, being found under bark or inside bored tunnel galleries. There are about 400 species in 25 genera in the family under the new, restricted circumscription, as opposed to 600 species in over 50 genera in the old definition. The oldest fossil assignable to the modern, more restricted definition of the family is Microtrogossita from the mid-Cretaceous Burmese amber of Myanmar, which has close affinities to the Trogossitini, indicating that the family had already considerably diversified by this time.
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.
Lamingtonium is the only genus in the family Lamingtoniidae, of the beetle superfamily Cucujoidea. It contains three species endemic to Australia. The holotype of the type species was collected on at Lamington National Park, Binna Burra, Queensland under the bark of a dead tree. The adults and larvae of two species have been found associated with basidiocarps of fungi belonging to the family Polyporaceae.
Sphindidae is a family of beetles, in the suborder Polyphaga. They are called slime mold beetles due to their exclusive feeding on slime molds during adult and larval stages, other aspects of their life history are obscure. Palaeontological discoveries since 2015 have added to the geologic history of Sphindidae, including the discovery of Libanopsis, placed in the extinct subfamily Libanopsinae.
Pterogeniidae is a family of beetles belonging to the superfamily Tenebrionoidea. They are found in South Asia, Southeast Asia, China, New Guinea and the Solomon Islands. Adults and larvae have been found associated with the fruiting bodies of polypore fungi, although adults can also be found in litter and debris.
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.
Clambidae is a family of beetles. They are known commonly as the minute beetles or the fringe-winged beetles. They are found worldwide on every continent except Antarctica.
Egoliinae is a subfamily of beetles in the family Trogossitidae. Members are native to South America and Australia. They are thought to be predatory.
Acalanthis is a genus of checkered beetles in the subfamily Egoliinae.
Eulichadidae is a family of beetles belonging to Elateriformia. There are two extant genera, Eulichas with several dozen species native to the Indomalayan realm of Asia, and Stenocolus, with a single species native to Western North America. The larvae are aquatic, with the larvae of Eulichas being found in sandy sediments of clean forest streams, while the larvae of Stenocolus are found under rocks and in leaf packs in low elevation streams and rivers. They are herbivious/saprophagous with larval specimens of Eulichas having been found with wood particles in their stomachs, while the larvae of Stenocolus are known to feed on decaying roots and detritus. The adults are terrestrial, with specimens of Eulichas typically found using light, while specimens of Stenocolus are typically found in riparian vegetation, and are not attracted to light. Potential extinct genera have been described from Mesozoic rocks, but the placement of several of these taxa in the family is disputed.
Eusphalerum is a genus of ocellate rove beetles in the family Staphylinidae. There are at least 130 described species in Eusphalerum.
Anthophagini is a tribe of ocellate rove beetles in the family Staphylinidae. There are at least 20 genera and 20 described species in Anthophagini.
Omaliini is a tribe of ocellate rove beetles in the family Staphylinidae. There are about 45 genera and 450 described species in Omaliini.
Rentoniidae is a family of beetles belonging to Cleroidea. The species were originally included in the family Trogossitidae. They are around 1–2 mm in length, with spherical bodies. Members of the family are native to the Southern Hemisphere, being found in Australia, New Zealand, New Caledonia and South America. They have been found on flowers, under the bark of dead trees, and in leaf litter, and members are known to be pollenivorous or fungivorous.
