Tonkinoscaris excisicollis is a species of beetle in the family Carabidae, the only species in the genus Tonkinoscaris.
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 83,000 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.
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.
Rhysodidae is a family of beetles, consisting of more than 350 species in about 20 genera.
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 Adephaga, with more than 40,000 recorded species in 10 families, are a suborder of highly specialized beetles and the second-largest suborder of the order Coleoptera. Members of this suborder are adephagans, a term which notably include ground beetles, tiger beetles, predacious diving beetles, and whirligig beetles. The majority of the species belongs to the family of carabids, or ground beetles (Carabidae).
The Trachypachidae are a family of beetles that generally resemble small ground beetles, but that are distinguished by the large coxae of their rearmost legs. There are only six known extant species in the family, with four species of Trachypachus found in northern Eurasia and northern North America, and two species of Systolosoma in Chile. They were much more diverse in the past, with many members belonging to the extinct subfamily Eodromeinae, the first fossils known of this family are of the genera Petrodromeus and Permunda from the Permian-Triassic boundary of Russia.
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.
Herbert Edward Andrewes was an English entomologist who specialised in beetles of the order Coleoptera.
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.
Bembidion is the largest genus of beetles in the family Carabidae by number of species. All species are small and move very fast. Most of them live close to water. The genus has a biantitropical distribution, meaning they are found in both the Northern and Southern Hemispheres, but not in the tropics. In warmer regions it is substituted by closely related Tachys and other genera.
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.
Agra schwarzeneggeri is a species of carabid beetle named after the actor Arnold Schwarzenegger. The holotype was collected in Costa Rica and first described to science in 2002.
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.
Platynus is a genus of ground beetles in the family Carabidae. There are at least 190 described species in Platynus.
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.
Elaphropus is a genus of ground beetles in the family Carabidae. There are at least 370 described species in Elaphropus.
Roger Naviaux is a French entomologist known for his work on beetles.
Stefano Ludovico Straneo was an Italian entomologist, teacher, academic administrator and author.
