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.
Dorcus is a genus of beetles in the family Lucanidae. Of the 30-odd species, most occur in Asia and India; two are found in southern Europe, and two species are from North America. Previously, specimens with serriform teeth on the mandibles and sable pigment were called Serrognathus whereas specimens with but a singular or multiple bulky notches on the mandibles and lustrous sable pigmentation were called Dorcus.
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.
Omophron is a genus of ground beetle (Carabidae), the only extant genus in the subfamily Omophroninae. It is mostly distributed in the Northern Hemisphere with the southern border running through Guatemala and Hispaniola in Americas, South Africa and Madagascar in Africa, Malaysia and Philippines in Asia.
Cyclommatus is a genus of the family Lucanidae, also known as the stag beetle. The majority of the species from the genus Cyclommatus are located in Southeast Asia, though some species are found in China and Taiwan as well. The genus Cyclommatus also consists of three subgenera: Cyclommatus, Cyclommatinus and Cyclommatellus. Each subgenera contains 80, 24 and 3 species respectively. In total, the genus Cyclommatus consists of a total of 134 species, though more are still being discovered to this day.

Promecheilidae is a family of beetles in the superfamily Tenebrionoidea. They were formerly included in a family called Perimylopidae. They are found in southern South America and associated archipelagos like South Georgia and the Falklands, New Zealand and Tasmania. Some species are associated tree ferns and moss-covered dead wood, and other forested habitats, while others are associated with peat bogs, grasslands and coastal habitats. They are probably phytophagus, feeding on lichen, moss, and other plant material.
