Tiger beetles are a family of beetles, Cicindelidae, known for their aggressive predatory habits and running speed. The fastest known species of tiger beetle, Rivacindela hudsoni, can run at a speed of 9 km/h, or about 125 body lengths per second. As of 2005, about 2,600 species and subspecies were known, with the richest diversity in the Oriental (Indo-Malayan) region, followed by the Neotropics. While historically treated as a subfamily of ground beetles (Carabidae) under the name Cicindelinae, several studies since 2020 indicated that they should be treated as a family, the Cicindelidae, which are a sister group to Carabidae within the Adephaga.
Ground beetles are a large, cosmopolitan family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily carnivorous, but some members are herbivorous or omnivorous.
Harpalinae is the largest subfamily of ground beetles, containing more than 19,000 species worldwide.
The Trachypachidae are a family of beetles that generally resemble small ground beetles, but that are distinguished by the large coxae of their rearmost legs. There are only six known extant species in the family, with four species of Trachypachus found in northern Eurasia and northern North America, and two species of Systolosoma in Chile and Argentina. They were much more diverse in the past, with dozens of described species from the Mesozoic.
Ant nest beetles or paussines, some members of which are known also as flanged bombardier beetles, are a large subfamily within the ground beetles (Carabidae).The tribes Metriini, Ozaenini, Paussini and Protopaussini are included in the subfamily.
Lebiinae is a subfamily of ground beetles in the family Carabidae. There are more than 330 genera and 6,300 described species in Lebiinae, in 5 tribes.
Lebia chlorocephala is a species of ground beetles in the Harpalinae subfamily.
Clinidium impressum is a species of ground beetle in the subfamily Rhysodinae. It was described by Ross T. Bell & J.R. Bell in 1985. It is known from French Guiana and Guyana. Male measures 5.3 mm (0.21 in) and females measure 6–6.2 mm (0.24–0.24 in) in length.
Clinidium moldenkei is a species of ground beetle in the subfamily Rhysodinae. It was described by R.T. Bell & J.R. Bell in 1985. It is endemic to the Golfo Dulce region in Puntarenas Province, Costa Rica. The species is named for the coleopterist Andrew R. Moldenke, collector of the holotype.
Clinidium segne is a species of ground beetle in the subfamily Rhysodinae. It was described by R.T. Bell & J.R. Bell in 1985. It is known from the Aragua state in northern Venezuela. Clinidium segne females measure 4.6–5.2 mm (0.18–0.20 in) in length.
Clinidium centrale is a species of ground beetle in the subfamily Rhysodinae. It was described by Antoine Henri Grouvelle in 1903. It is endemic to Costa Rica. Clinidium centrale measure 6–7.4 mm (0.24–0.29 in) in length.
Clinidium insigne is a species of ground beetle in the subfamily Rhysodinae. It was described by Antoine Henri Grouvelle in 1903. It is known from Ecuador, provisionally from Cali, Colombia, and Yacambú National Park in Venezuela.
Clinidium integrum is a species of ground beetle in the subfamily Rhysodinae. It was described by Antoine Henri Grouvelle in 1903. It is known from its type locality in western Amazonas state, Brazil, and from Leticia in Amazonas Department, Colombia.
Clinidium granatense is a species of ground beetle in the subfamily Rhysodinae. It was described by Louis Alexandre Auguste Chevrolat in 1873. It is known from Colombia.
Clinidium rojasi is a species of ground beetle in the subfamily Rhysodinae. It was described by Louis Alexandre Auguste Chevrolat in 1873. It is known from the mountains of northern Venezuela between Falcón and Aragua states and from Guyana.
Rhyzodiastes denticauda is a species of ground beetle in the subfamily Rhysodinae. It was described by R.T. Bell and J.R. Bell in 1985. It is found in Sarawak.
Harpalus quadratus is a species of ground beetle in the subfamily Harpalinae. It was described by Maximilien Chaudoir in 1846. Its range is reported to cover Asia Minor and the Caucasus, and it lives in mountainous regions.
Ross Taylor Bell was an American entomologist with particular interest in the invertebrate natural history of Vermont, United States, and carabid beetles. Together with his wife, Joyce Rockenbach Bell, his work at the University of Vermont was largely taxonomic, where they described more than 75% of the rhysodine species known to science. Ross also wrote a number of seminal papers in his chosen field.
Carabus chamissonis is a species of ground beetle in the family Carabidae. It is found in tundra regions across northern Canada and Alaska, as well as isolated populations on Mount Washington, New Hampshire and Katahdin in Maine. This is a species of open, dry tundra environments - generally better drained than those occupied in the Arctic by Carabus truncaticollis
Clinidium oberthueri is a species of ground beetle in the subfamily Rhysodinae. It was described by Antoine Henri Grouvelle in 1903. It is known from Ecuador where it is known with certainty from the eastern side of the Andes, and from Barbacoas, Nariño, on the other versant of the Andes in Colombia.
