Diaphoromyrma
''Diaphoromyrma'' (from Greek ''diaphoros'', "different"/"remarkable", + ''myrmekos'', "ant") is a genus of ants in the subfamily Myrmicinae. It contains the single species ''Diaphoromyrma sofiae'', known only from workers from the type locality in Bahia, Brazil. The genus is apparently close to ''Allomerus'' and '' Diplomorium'' in the Solenopsidini, but its tribal attribution remains uncertain. Distribution and habitat The genus is known only from workers from Bahia, Brazil. The species was collected in litter samples taken in three rain forest remnants in the extreme southern portion of Bahia using the Winkler extraction. The landscape is dominated by forested valleys inserted in the coastal plateau (Barreiras Formation, Tertiary origin). Most of the vegetation of the remnants was in an initial or medium stage of regeneration, in a region where eucalypt plantations currently predominate. Description ''Diaphoromyrma'' workers are characterized by the following traits: Antenna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pheidolini
Fungus-growing ants (tribe Attini) comprise all the known fungus-growing ant species participating in ant–fungus mutualism. They are known for cutting grasses and leaves, carrying them to their colonies' nests, and using them to grow fungus on which they later feed. Their farming habits typically have large effects on their surrounding ecosystem. Many species farm large areas surrounding their colonies and leave walking trails that compress the soil, which can no longer grow plants. Attine colonies commonly have millions of individuals, though some species only house a few hundred. They are the sister group to the subtribe Dacetina. Leafcutter ants, including ''Atta (genus), Atta'' and ''Acromyrmex'', make up two of the genera. Their cultivars mostly come from the fungal tribe Leucocoprinus, Leucocoprineae of family Agaricaceae. Attine gut microbiota is often not diverse due to their primarily monotonous diets, leaving them at a higher risk than other beings for certain illnes ...

Myrmicinae
Myrmicinae is a subfamily of ants, with about 140 extant genera; their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees.Goulet, H & Huber, JT (eds.) (1993) Hymenoptera of the world: an identification guide to families. Agriculture Canada. p. 224 Identification Myrmicine worker ants have a distinct postpetiole, i.e., abdominal segment III is notably smaller than segment IV and set off from it by a well-developed constriction; the pronotum is inflexibly fused to the rest of the mesosoma, such that the promesonotal suture is weakly impressed or absent, and a functional sting is usually present. The clypeus is well-developed; as a result, the antennal sockets are well separated from the anterior margin of the head. Most myrmicine genera possess well-developed eyes and frontal lobes that partly conceal the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Myrmicini
Myrmicini is a tribe of ants in the subfamily Myrmicinae. It is not to be confused with the very similar-sounding tribes Myrmecinini (also in subfamily Myrmicinae) and Myrmeciini, which is in the subfamily Myrmeciinae. While the type genus of Myrmicini is ''Myrmica'', that of Myrmeciini is ''Myrmecia'' and that of Myrmecinini '' Myrmecina''.

Dolopomyrmex
''Dolopomyrmex'' is a genus of ants in the subfamily Myrmicinae containing the single species ''Dolopomyrmex pilatus''. Distribution and habitat The genus is known from the western and the southwestern United States, where the ants live in arid desert habitats, likely with an almost exclusively subterranean life style. Etymology The genus name is derived from ancient Greek ''dolops'', ''dolopos'' ("lurker in ambush") + Greek ''myrmex'', ''myrmekos'' ("ant"); the specific name of the type species (''D. pilatus'') is derived from the pilum (a javelin A javelin is a light spear designed primarily to be thrown, historically as a ranged weapon, but today predominantly for sport. The javelin is almost always thrown by hand, unlike the sling, bow, and crossbow, which launch projectiles with th ... commonly used by the Roman army), making ''Dolopomyrmex pilatus'' the "spear-bearing ambush ant".

Tyrannomyrmex
''Tyrannomyrmex'' is a rare tropical genus of ants in the subfamily Myrmicinae. Three similar species, only known from workers, are recognized and share small eyes and edentate mandibles. Species Two of the species are known only from single worker specimens, but a single male specimen collected in 1965 possibly represents the male of an otherwise unknown species, and ''T. alii'' is known from a series of over 35 gynes and workers. So far, all species of ''Tyrannomyrmex'' occur in tropical Old World forests. The wide distribution range from India and Sri Lanka in the west to peninsular Malaysia and perhaps the Philippine archipelago in the east suggests that more species may be discovered. * ''Tyrannomyrmex alii'' Sadasivan & Kripakaran, 2017 - Western Ghats, India * ''Tyrannomyrmex dux'' Borowiec, 2007 – Kerala, India * ''Tyrannomyrmex legatus'' Alpert, 2013 – Sinharaja Forest Reserve, Sri Lanka * ''Tyrannomyrmex rex'' Fernández, 2003 – Negri ...

Sternite
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 crustacea ...
