The Phalacridae are a family of beetles commonly called the shining flower beetles, They are often found in composite flowers. They are oval-shaped, usually tan, and aboout 2 mm in length. Most species feed on fungus, although a number feed on flower heads.
Colydiinae is a subfamily of beetles, commonly known as cylindrical bark beetles. They have been treated historically as a family Colydiidae, but have been moved into the Zopheridae, where they constitute the bulk of the diversity of the newly expanded family, with about 140 genera worldwide. They are diverse for example in the Australian region, from where about 35 genera are known; in Europe, though, only 20 genera are found and many of these only with few species.
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).
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.
Cerylonidae are small to tiny, smooth, shiny, hairless beetles, only lightly punctured. There are about 450 species worldwide in 50 or so genera, mostly tropical and subtropical. They are most common under the bark of dead trees, but can also occur in compost and other decaying plant material. Little is known specifically about their biology but they are thought to be either predators that feed on other small animals, or fungus-feeders.
The Mycetophagidae or hairy fungus beetles are a family of beetles in the superfamily Tenebrionoidea. The different species are between 1.0 and 6.5 mm in length. The larvae and adults live in decaying leaf litter, fungi, and under bark. Most species feed on fungi. Worldwide, the 18 genera contain around 200 species.
Salpingidae or narrow-waisted bark beetles is a family of beetles in the superfamily Tenebrionoidea. The species are small, about 1.5 – 7 mm in length. The family is globally distributed and consists of about 45 genera and 300 species, which are generally found in the temperate regions of both hemispheres. The family is mainly associated with plants as well as with ascomycete and hyphomycete fungi. Some members of the family are associated with unusual habitats, like Aegialites and Antarcticodomus, which are found in coastal areas including the intertidal zone, with former feeding on algae.
Bradycellus is a genus in the beetle family Carabidae. There are more than 120 described species in Bradycellus.
Anthribinae is a subfamily of fungus weevils in the family of beetles known as Anthribidae. There are over 50 genera and more than 80 described species in Anthribinae.
Namunaria is a genus of cylindrical bark beetles in the family Zopheridae, first described by Edmund Reitter in 1882. There are at least two described species in Namunaria.
Synchitini is a tribe of cylindrical bark beetles in the family Zopheridae. There are about 19 genera and at least 40 described species in Synchitini.
Pycnomerus is a genus of ironclad beetles in the family Zopheridae. There are more than 20 described species in Pycnomerus.
Megataphrus is a genus of cylindrical bark beetles in the family Zopheridae. There are at least three described species in Megataphrus.
Monoedus is a genus of cylindrical bark beetles in the family Zopheridae. There are about eight described species in Monoedus.
Coxelus is a genus of cylindrical bark beetles in the family Zopheridae. There are about 10 described species of Coxelus.
Nematidium is a genus of cylindrical bark beetles in the family Zopheridae. There are at least three described species in Nematidium.
Synchita is a genus of cylindrical bark beetles in the family Zopheridae. There are about 20 described species in Synchita. The genus was first described in 1792 by Johann Christian Ludwig Hellwig.
