Duvalius is a genus of beetles in the family Carabidae. [1] [2] 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. [3]
The genus includes the following species: [2]
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.
Pterostichus is a very large genus of ground beetles with a Holarctic distribution in the subfamily Harpalinae. It has over 1,200 species. The beetles are predatory, but sometimes feed on strawberries. They can be found under rocks and prefer slightly moist, sandy soil although preferences differ between species.
Trechus is a genus of ground beetle native to the Palearctic and the Near East. There are more than 1,000 described species in Trechus.
Speluncarius is a genus of beetles in the family Carabidae, containing the following species:
Scaritinae is a large subfamily of beetles in the family Carabidae, containing more than 2400 species in over 140 genera. They are found worldwide.
Typhloreicheia is a genus of beetles in the family Carabidae, containing the following species:
Caecoparvus is a genus of ground beetles in the family Carabidae. There are more than 20 described species in Caecoparvus.
Winklerites is a genus of ground beetles in the family Carabidae. There are more than 20 described species in Winklerites.
Ocys is a genus of ground beetles in the family Carabidae. There are at least 30 described species in Ocys.
Orotrechus is a genus of troglobitic beetles in the family Carabidae, containing the following species:
Trechini is a large tribe of ground beetles in the family Carabidae. There are more than 270 genera and over 2,400 described species in Trechini, found throughout the world.
