of beetles in the family Carabidae
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 fami ...

All species are small (less than 7.5 mm) and move very fast. Most of them live close to water. The genus has a biantitropical distribution
Antitropical (alternatives include biantitropical or amphitropical) distribution is a type of disjunct distribution where a species or clade exists at comparable latitudes across the equator but not in the tropics. For example, a species may be fou ...

Taxonomy
There have been many attempts to divide it into smaller genera, most notably byRené Jeannel
René Jeannel (23 March 1879 – 20 February 1965) was a French entomologist.Jean-Jacques Amigo, « Jeannel (René, Gabriel, Marie) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, ...

This genus is divided into numerus subgenera
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus.
In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between t ...
