Ground beetles are a large, cosmopolitan family of beetles, Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. It is one of the ten most speciose animal families, as of 2015.
Calathus is a genus of ground beetle native to the Palearctic, the Near East and North Africa. There are at least 190 described species in Calathus.
Walther Hermann Richard Horn was a German entomologist who specialised in beetles (Coleoptera). He was born in Berlin, where he also died. He is not to be confused with the American entomologist George Henry Horn, another entomologist that studied Coleoptera.
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.
Calosoma is a genus of large ground beetles that occur primarily throughout the Northern Hemisphere, and are referred to as caterpillar hunters or searchers. Many of the 167 species are largely or entirely black, but some have bright metallic coloration. They produce a foul-smelling spray from glands near the tip of the abdomen. They are recognizable due to their large thorax, which is almost the size of their abdomen and much wider than their head.
Nebria is a genus of ground beetles native to the Palearctic, the Near East and North Africa.
Clivina is a genus of ground beetle native to the Palearctic, the Nearctic, the Near East and North Africa. There are at least 580 described species in Clivina.
Chlaenius is a large and diverse genus of ground beetle. It is native to the Palearctic, the Near East, North Africa, Afrotropical region, and the Nearctic. Worldwide, roughly 1,000 species are currently recognized with the majority of known species occurring in the Oriental and Afrotropical regions. The genus is divided into many subgenera.

Psydrinae is a subfamily of beetles in the family Carabidae.
Rhysodinae is a subfamily of wrinkled bark beetles in the family Carabidae. The group of genera making up Rhysodinae has been treated as the family Rhysodidae in the past, and DNA analysis has more recently supported treating it as the tribe Rhysodini.
Omoglymmius is a genus of wrinkled bark beetles in the family Carabidae, found on every continent except Africa and Antarctica. There are at least 150 species in Omoglymmius.
