Omophron Aequale
''Omophron aequale'' is a species of ground beetle in the family Carabidae. It is distributed in East Asia. The species is very similar to ''Omophron limbatum''. Although the puncturation (the arrangement of punctures) on the pronotum of ''O. aequale'' is a little finer than that of ''O. limbatum'', it is denser. The species also has denser and coarser puncturation on the side margins of the first two sternites. ''Omophron aequale'' is divided into 2 subspecies: ''O. aequale aequale'' and ''O. aequale jacobsoni''. ''O. aequale aequale'' has a length between 6.4 and 7.2 mm and a width between 4.2 and 4.4 mm. It is distributed in Japan and Sakhalin Island Sakhalin ( rus, Сахали́н, r=Sakhalín, p=səxɐˈlʲin; ja, 樺太 ''Karafuto''; zh, c=, p=Kùyèdǎo, s=库页岛, t=庫頁島; Manchu: ᠰᠠᡥᠠᠯᡳᠶᠠᠨ, ''Sahaliyan''; Orok: Бугата на̄, ''Bugata nā''; Nivkh: ..., Russia.

Ground Beetle
Ground beetles are a large, cosmopolitan distribution, cosmopolitan family (biology), family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily carnivorous, but some members are phytophagous or omnivorous. Description and ecology Although their body shapes and coloring vary somewhat, most are shiny black or metallic and have ridged wing covers (elytra). The elytra are fused in some species, particularly the large Carabinae, rendering the beetles unable to fly. The species ''Mormolyce phyllodes'' is known as violin beetle due to their peculiarly shaped elytra. All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their arthropod leg, fore leg tibiae bearing a comb of hairs used for cleaning their antenna (biology), antennae. ...

Omophron Limbatum
file:Omophron nitidum P1440156a.jpg, ''Omophron nitidum'' ''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.

Pronotum
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also *Glossary of entomolo ...

Sternites
The sternum (pl. "sterna") is the ventral portion of a segment of an arthropod thorax or abdomen. In insects, the sterna are usually single, large sclerites, and external. However, they can sometimes be divided in two or more, in which case the subunits are called sternites, and may also be modified on the terminal abdominal segments so as to form part of the functional genitalia, in which case they are frequently reduced in size and development, and may become internalized and/or membranous. For a detailed explanation of the terminology, see Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods.Sørensen, M. V. et al. Phylogeny of Kinorhyncha based on morphology and two molecular loci. PLoS One 10, 1–33 (2015). Ventrites are externally visible sternites. Usually the first sternite is covered up, so that vertrite numbers do not correspond to sternid numbers. The term is also used in other arthropod groups such as crustaceans ...

Sakhalin
Sakhalin ( rus, Сахали́н, r=Sakhalín, p=səxɐˈlʲin; ja, 樺太 ''Karafuto''; zh, c=, p=Kùyèdǎo, s=库页岛, t=庫頁島; Manchu: ᠰᠠᡥᠠᠯᡳᠶᠠᠨ, ''Sahaliyan''; Orok: Бугата на̄, ''Bugata nā''; Nivkh: Yh-mif) is the largest island of Russia. It is north of the Japanese archipelago, and is administered as part of the Sakhalin Oblast. Sakhalin is situated in the Pacific Ocean, sandwiched between the Sea of Okhotsk to the east and the Sea of Japan to the west. It is located just off Khabarovsk Krai, and is north of Hokkaido in Japan. The island has a population of roughly 500,000, the majority of which are Russians. The indigenous peoples of the island are the Ainu, Oroks, and Nivkhs, who are now present in very small numbers. The Island's name is derived from the Manchu word ''Sahaliyan'' (ᠰᠠᡥᠠᠯᡳᠶᠠᠨ). Sakhalin was once part of China during the Qing dynasty, although Chinese control was relaxed at times. Sakhalin was l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetles Described In 1863
Beetles are 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 described 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, with estimates suggesting that there are between 0.9 and 2.1 million total species. 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 (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exosk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
