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 Megalopodidae are a small family of leaf beetles, previously included as a subfamily within the Chrysomelidae. One of its constituent subfamilies, Zeugophorinae, has also frequently been treated as a subfamily within Chrysomelidae. The family contains approximately 30 genera worldwide, primarily in the nominate subfamily Megalopodinae, and mostly circumtropical.
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.
Silvanidae, "silvan flat bark beetles", is a family of beetles in the superfamily Cucujoidea, consisting of 68 described genera and about 500 described species. The family is represented on all continents except Antarctica, and is most diverse at both the generic and species levels in the Old World tropics.
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:
Carabinae is a subfamily of ground beetles in the family Carabidae. There are about 10 genera and more than 1,400 described species in Carabinae.
Harpalus stevensi is a species of ground beetle in the subfamily Harpalinae. It was described by Kataev in 2011. Two new species of the genus HarpalusLatreille, 1802 were described: H. stevensi from China (Sichuan) and H. dudkoi from Turkey (Adana). Both species belong to the nominotypical subgenus and are included in the tardus species-group.
Scolytus jacobsoni is an elm bark beetle occurring in forests of mixed broad-leaves with elm trees in Asia. In southeastern Russia, during years of outbreaks S. jacobsoni often attacks healthy trees along forest edges or standing alone along roads and in fields and gardens, making it an important pest for elm trees there. Reported hosts include Ulmus davidiana, Ulmus japonica, Ulmus laciniata, Ulmus propinqua, Carpinus betulus, and Pyrus ussuriensis.
Thanasimodes is a genus of beetles in the subfamily Clerinae.
Mecodema manaia is a medium-sized ground beetle species found in the native forests of Bream Head and Mt Manaia, Northland, New Zealand. This species shares the forests of Bream Head with a large-bodied species, Mecodema tewhara, with both inhabiting slightly different forest type.
Omophron ovale, the oval round sand beetle, is a species of ground beetle in the family Carabidae. It is found in North America. Inhabiting mostly the margins of freshwater ponds, streams, and lakes, O. ovale are riparian and burrow into sand and mud. O. ovale, as all Carabidae, go through complete metamorphosis. This consists of three distinct stages before becoming an adult— egg, then larva, then pupa. O. ovale are around 4.5mm to 6.6mm in length and have a distinctive pattern on their body, with yellowish tan and metallic green markings.
Omophron americanum, the American round sand beetle, is a species of ground beetle in the family Carabidae. It is found in, as well as native to, North America, ranging across most of the United States and Canada, except British Columbia.
Mecodema atrox is a medium-sized ground beetle species that is closely related to Mecodema curvidens. Mecodema atrox is relatively rare in comparison due to its preferred habitat, the coastal broadleaf forests of the Coromandel Peninsula, a forest type that is in decline. The body of Mecodema atrox is black and the legs are dark reddish-brown. They can be distinguished from other Mecodema species by a number of characters, including the pattern of asetose punctures along the elytral striae.
Mecodema crenaticolle is a medium-bodied ground beetle that is endemic to New Zealand. It is one of the three species within the ducale species group and is the only species of this group found in the North Island, New Zealand. Its range extends from the Wellington Region to Hunua Range, southeast Auckland, and is relatively common in most native forest habitats.
Mecodema moniliferum is a medium-sized ground beetle endemic to the South island, New Zealand. This species is part of the monophyletic curvidens group and is found on the braided-river systems of the South Island.
Omophron axillare is a species of ground beetle in the family Carabidae.
Omophron brettinghamae is a species of ground beetle in the family Carabidae. It is distributed in Bangladesh and Vietnam.
Omophron chelys is a species of ground beetle in the family Carabidae. It is distributed in northeastern India, in the state of Sikkim.
Onthophagus falsus, is a species of dung beetle found in India, Sri Lanka and Pakistan.
