Pelecium is a genus of beetles in the family Carabidae, containing the following species: [1]
Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils) with some 70,000 member species, belongs to this order. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
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, Cicindela 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. 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.
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:
Pheropsophus is a genus of beetles in the family Carabidae, containing the following species:
Lebiinae is a subfamily of beetles in the family Carabidae.
Pentagonica is a genus of beetles in the family Carabidae, containing the following species:
Panagaeinae is a subfamily of beetles in the family Carabidae, containing the following genera:
Ardistomopsis is a genus of beetles in the family Carabidae, containing the following species:
Eripus is a genus of beetles in the family Carabidae, containing the following species:
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.
Abacetus is a genus of beetles in the family Carabidae, distributed across Africa, Asia and Australia, with a single European species. It contains the following species:
Morion is a genus of beetles in the family Carabidae, containing the following species:
Trirammatus is a genus of beetles in the family Carabidae, containing the following species:

Trechinae is a subfamily in the ground beetle family, Carabidae.
