The Zopheridae family of beetles has grown considerably in recent years as the members of two other families have been included within its circumscription; these former families are the Monommatidae and the Colydiidae, which are now both included in the Zopheridae as subfamilies or even as tribe of subfamily Zopherinae. Some authors accept up to six subfamilies here, while others merge all except the Colydiinae into the Zopherinae.
Tetratomidae is a small family of beetles sometimes called polypore fungus beetles. The family consists of several genera, most of which used to be in the family Melandryidae. Tetratomidae can be found worldwide.
Cantharis is a large genus of soldier beetles in the family Cantharidae with narrow and soft elytra.
Kateretidae also known as short-winged flower beetles are a family of beetles in the superfamily Cucujoidea. There are 10 extant and 4 extinct genera, and at least 40 described species. They are found worldwide except in New Zealand. Adults are anthophagous, feeding on flowers, while the larvae are spermatophagous inside the flower corolla.
Sphindidae is a family of beetles, in the suborder Polyphaga. They are also known as 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.
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.
Rhizophagus is a genus of beetles in the family Monotomidae, containing the following species:
Olibrus is a genus of shining flower beetles in the family Phalacridae. There are at least 30 described species in Olibrus.
Orchesia is a genus of false darkling beetles in the family Melandryidae. There are about 19 described species in Orchesia.
Osphya is a genus of false darkling beetles in the family Melandryidae. There are about seven described species in Osphya.
Zilora is a genus of false darkling beetles in the family Melandryidae. There are about seven described species in Zilora.
Dircaea is a genus of beetles belonging to the family Melandryidae. The species of this genus are found in Europe, Japan and North America.
