Tiger beetles are a large group of beetles, from the Cicindelinae subfamily, 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.
Harpalinae is a huge subfamily of ground beetles that contains 20,000 species or ~6,400 spp. in 24 tribes worldwide, according to others. A rarely used common name for the subfamily is the harp beetles. The Harpalinae contain the most apomorphic ground beetles, displaying a wide range of forms and behaviors. Some are, rare among ground beetles, omnivores or even herbivores.
Carabus is a genus of beetles in family Carabidae. The genus is highly diverse with 91 subgenera and more than 1000 recognised species, thus is the largest genus in the subfamily Carabinae. The vast majority are native to the Palearctic, but 11 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.
Pterostichus is a very large genus of ground beetles with a Holarctic distribution in the subfamily Harpalinae. It has over 1,100 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. Pterostichus contains the following species:
Leistus is a genus of ground beetle native to the Palearctic and the Nearctic. It contains the following species:
Brachinus is a genus of ground beetle native to the Nearctic, Palearctic, the Near East and North Africa. Beetles in this genus are commonly referred to as bombardier beetles. The genus contains the following species:
Badister is a genus of ground beetle in the family Carabidae native to North Africa, the Near East and the Palearctic, including Europe.
Trechus is a genus of ground beetle native to the Palearctic and the Near East. The name is derived from the Greek word trécho, meaning "I run".
Acupalpus is a genus of insect-eating beetle species. Its representatives are found across Europe, Asia, and North America.
Parophonus is a genus of beetles in the family Carabidae, containing the following species:
Platyninae is a subfamily of ground beetles. Occasionally it was treated as a tribe Platynini of subfamily Harpalinae, particularly when this was circumscribed loosely.
Pterostichinae is a subfamily of ground beetles. It belongs to the advanced harpaline assemblage, and if these are circumscribed sensu lato as a single subfamily, Pterostichinae are downranked to a tribe Pterostichini. However, as the former Pterostichitae supertribe of the Harpalinae as loosely circumscribed does seem to constitute a lineage rather distinct from Harpalus, its core group is here considered to be the present subfamily and the Harpalinae are defined more narrowly.
Trechinae is a subfamily in the ground beetle family, Carabidae.
Epaphiopsis is a genus of beetles in the family Carabidae, containing the following species:
Orotrechus is a genus of troglobitic beetles in the family Carabidae, containing the following species:
Trechisibus is a genus of beetles in the family Carabidae, containing the following species:
Trechodes is a genus of beetles in the family Carabidae, containing the following species:
Cicindelini is a tribe of tiger beetles in the family Carabidae, containing the overwhelming majority of genera (>110) and species in the subfamily.
