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.
Amara is a large genus of carabid beetles, commonly called the sun beetles. Many are holarctic, but a few species are neotropical or occur in eastern Asia.
The Indian egg-eating snake or Indian egg-eater is a rare species of egg-eating snake in the family Colubridae. The species is endemic to the Indian subcontinent. It is also called Westermann's snake, reflecting its scientific name. The snake belongs to the monotypic genus Elachistodon.
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.
Lepicerus is a genus of myxophagan beetles containing three described species in the family Lepiceridae; it is the only extant genus in the family, with another genus, Lepiceratus only known from fossils. Extant species occur in the Neotropics, from Mexico south to Venezuela and Ecuador. Fossils referrable to the genus are known from the early Late Cretaceous of Southeast Asia.
Eobroscus is a genus of beetles in the family Carabidae which was circumscribed by Oleg Leonidovich Kryzhanovsky in 1951. Its species are found in Russia, China, Korea, Japan, China, Taiwan, Bhutan, and Vietnam. As of 2017, it contains the following three species:
Guatemalteca is a genus of beetle in the family Carabidae. As of 2017, its only described species is its type species, Guatemalteca virgen. When Terry Erwin named the genus in 2004, he placed it in the tribe Lachnophorini; in 2014 he and Laura S. Zamorano placed it in the subtribe Eucaerina.
Nanodiodes is a genus in the beetle family Carabidae. There are about five described species in Nanodiodes.
Holcaspis is a genus of beetles in the family Carabidae, endemic to New Zealand.
Trechinae is a subfamily of ground beetles in the family Carabidae. There are 6 tribes, more than 430 genera, and over 6,700 described species in Trechinae.
Hydrodytes is a genus of predaceous diving beetles in the family Dytiscidae. There are at least three described species in Hydrodytes. It is found in North America and the Neotropics.
Ross Taylor Bell was an American entomologist with particular interest in the invertebrate natural history of Vermont, United States, and carabid beetles. Together with his wife, Joyce Rockenbach Bell, his work at the University of Vermont was largely taxonomic, where they described more than 75% of the rhysodine species known to science. Ross also wrote a number of seminal papers in his chosen field.
Lachnophorini is a tribe of ground beetles in the family Carabidae. There are about 18 genera and more than 190 described species in Lachnophorini.
Erynephala is a genus of skeletonizing leaf beetles in the family Chrysomelidae. There are six described species in Erynephala. They are found in North America and the Neotropics.
Apterodela unipunctata, the one-spotted tiger beetle, is a species of flashy tiger beetle in the family Cicindelidae. It is found in North America. This species was formerly in the genus Cylindera. It is has a Nearctic distribution and lives in open forest and leaf litter. It is believed to be the sister taxon to Apterodela ovipennis.
Hydrodytinae is a subfamily of predaceous diving beetles in the family Dytiscidae. There are at least two genera and four described species in Hydrodytinae.
