Alexiidae is a family of beetles. It contains a single genus, Sphaerosoma, formerly included within the family Cerylonidae, with around 50 species which are native to the western Palearctic. Species of Sphaerosoma are very small, around 1 to 2 mm in length rounded beetles with clubbed antennae. They are fungivores, having been observed feeding on mushrooms, and have also been found in leaf litter and on decaying bark. [1]
There has been considerable confusion regarding the type species and authorship of the genus; most older sources consider the author and species to be Sphaerosoma quercus Samouelle, 1819. That name is now considered to be a nomen nudum, and the valid name for Samouelle's species is Sphaerosoma piliferum (Müller, 1821). The type species is now considered to be Sphaerosoma quercus Stephens, 1832, which is itself a junior synonym of Sphaerosoma pilosum (Panzer, 1793). [2] Alexiidae has been recovered as part of the superfamily Coccinelloidea as the sister group of Latridiidae. [3]
Zopheridae is a family of beetles belonging to Tenebrionoidea. It 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.
Cryptophagidae is a family of beetles with representatives found in all biogeographic realms. Members of this family are commonly called silken fungus beetles and both adults and larvae appear to feed exclusively on fungi although in a wide variety of habitats and situations, such as rotting wood and shed animal fur and feathers. These beetles vary from about 1 to 11 millimeters long, and usually have an oval body shape with a slight "waist".
Carabus is a genus of beetles in family Carabidae. The genus is highly diverse with 94 subgenera, 959 species and 2300 subspecies, thus is the largest genus in the subfamily Carabinae. The vast majority are native to the Palearctic, but 16 Nearctic species are also known. Carabus spp. are 12–50 mm (0.47–1.97 in) long, and most species are wingless and often very colourful. These are nocturnal, predatory beetles that feed on snails, earthworms, and caterpillars. Most Carabus species were thought to have inhabited the Eurasian forest, but the species' low dispersal abilities altered the distribution of lineages within the genus.
Zabrus is a genus of ground beetles. They are, unusually for ground beetles, omnivores or even herbivores, and Zabrus tenebrioides can become a pest in cereal fields.
Licinus is a genus of in the beetle family Carabidae native to the Palearctic, the Near East and North Africa.
Molops is a genus in the beetle family Carabidae. There are more than 40 described species in Molops, found primarily in Europe.
Attagenus is a genus of beetles. This genus is found in tropical Africa, the Palearctic including Europe, the Near East, the Nearctic, North Africa and East Asia. There are nearly 200 species. The genus has existed for at least 99 million years, with fossils known from the Cenomanian aged Burmese amber and Turonian aged New Jersey amber.
Silvanidae, "silvan flat bark beetles", is a family of beetles in the superfamily Cucujoidea, consisting of 68 described genera and about 500 described species. The family is represented on all continents except Antarctica, and is most diverse at both the generic and species levels in the Old World tropics.
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.
Anthaxia is a genus of beetles in the family Buprestidae.
Omphreus is a genus of beetles in the family Carabidae, containing the following species:
Agapanthia is a genus of flat-faced longhorn beetle belonging to the family Cerambycidae, subfamily Lamiinae.
Tapinopterus is a genus of in the beetle family Carabidae. There are more than 70 described species in Tapinopterus, found in Europe and southwest Asia.
Duvalius is a genus of beetles in the family Carabidae. They are distributed from the Mediterranean area to northwestern China. They typically live in caves and in shallow subterranean spaces. Many species are rare and have very restricted distributions.
Dorcadion is a genus of longhorn beetles of the subfamily Lamiinae.
Phytoecia is a genus of longhorn beetles of the subfamily Lamiinae,
Pycnomerus is a genus of ironclad beetles in the family Zopheridae. There are more than 20 described species in Pycnomerus.
Simplocaria is a genus of pill beetles in the family Byrrhidae. There are more than 30 described species in Simplocaria.
