Linepithema Fuscum
''Linepithema fuscum'' is a species of ant in the genus ''Linepithema''. Described by Mayr in 1866, the species is endemic to South America. ''Linepithema fucsum'' was the first species-level name assigned to genus ''Linepithema'' by Mayr. It is related to ''L. angulatum, L. keiteli, L. piliferum and L. tsachila.'' However, only ''Linepithema fuscum'' remains without a worker association and it could be possible that males of ''Linepithema fuscum'' actually belong to the workers of ''L. angulatum.'' Little is known about ''Linepithema fuscum'' due to the scarcity of the collected samples. Taxonomy In 1866, Mayr first described ''Linepithema fuscum'' and 28 species-level names have been assigned to the genus ''Linepithema'' ever since. However, species limit within ''Linepithema'' is poorly understood and there haven't been efforts to synthesize the isolated description of the species into one coherent taxonomy. The description of ''Linepithema fuscum'' was initially based on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linepithema
''Linepithema'' is a genus of small ants in the subfamily Dolichoderinae. Distribution Their native distribution rage from northern Mexico, east into the Caribbean, and south into northern Argentina. Two species have been spread around the world by human activities: ''L. iniquum'' and ''L. humile''. The latter is better known as the Argentine ant, an invasive species with notable presence in Mediterranean climates. ''Linepithema'' species are found from sea level and up to 4,000 meters above sea level in the Andes The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S ....

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Propodeum
The propodeum or propodium is the first abdominal segment in Apocrita Hymenoptera (wasps, bees and ants). It is fused with the thorax to form the mesosoma. It is a single large sclerite, not subdivided, and bears a pair of spiracles. It is strongly constricted posteriorly to form the articulation of the petiole, and gives apocritans their distinctive shape. There may be a suture between the propodeum and the thorax, like in Symphyta Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay ... or not, and the presence or absence of such suture can aid in identifying specimens. In molluscs Propodium is the anterior (frontal) part of the foot of a mollusk. References Insect anatomy Gastropod anatomy {{insect-anatomy-stub ...

Dolichoderinae
Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant (''Linepithema humile''), the erratic ant, the odorous house ant, and the cone ant. The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic realms, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions. This subfamily is distinguished by having a single petiole (no post-petiole) and a slit-like orifice, from which chemical compounds are released. Dolichoderine ants do not possess a sting, unlike ants in some other subfamilies, such as Ponerinae and Myrmicinae, instead relying on the chemical defensive compounds produced from the anal gland. Of the compounds produced by dolichoderine ants, several terpenoids were identified including the previously unknown iridomyrmecin, isoiridomyrmecin, and iridodial. Such compounds are responsible for the smell given off by ants of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera Of South America
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
