Kempfidris
''Kempfidris'' is a Neotropical genus of ants in the subfamily Myrmicinae containing the single species ''Kempfidris inusualis''. Known from Brazil, Ecuador and Venezuela, the species was originally described as ''Monomorium inusuale'' in 2007, but was reclassified as the type species for the new genus ''Kempfidris'' in 2014. The species is only known from workers and almost nothing is known about their natural history. Description The genus was described in 2014 based on the workers of a single species, ''K. inusualis'', originally described by and provisionally placed in ''Monomorium'' awaiting a better understanding of the internal relationships in Myrmicinae. ''Kempfidris'' has a series of distinctive morphological characters including the mandibular configuration, vestibulate propodeal spiracle, propodeal carinae, and cylindrical micro-pegs on the posteromedian portion of abdominal tergum VI and anteromedian portion of abdominal tergum VII. This last trait appears to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

Tergum
A ''tergum'' (Latin for "the back"; plural ''terga'', associated adjective tergal) is the dorsal ('upper') portion of an arthropod segment other than the head. The anterior edge is called the 'base' and posterior edge is called the 'apex' or 'margin'. A given tergum may be divided into hardened plates or sclerites commonly referred to as tergites. In a thoracic segment, for example, the tergum may be divided into an anterior notum and a posterior scutellum. Lateral extensions of a tergite are known as paranota (Greek for "alongside the back") or ''carinae'' (Latin for "keel"), exemplified by the flat-backed millipedes of the order Polydesmida. Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods. Tergo-tergal is a stridulatory mechanism in which fine spines of the abdominal tergites are rubbed together to produce sound. This process is known as abdominal telescoping.

Pachycondyla Crassinoda
''Pachycondyla'' is a ponerine genus of ants found in the Neotropics. Distribution ''Pachycondyla'' is currently distributed from southern United States to northern Argentina, but some fossil species (e.g. '' P. eocenica'' and '' P. lutzi'') are found in Europe. Species The genus formerly contained hundreds of species, most of them belonging to at the time junior synonyms of ''Pachycondyla''. While revising the ponerines, Schmidt & Shattuck (2014) revived many of the former synonyms, leaving only eleven species in ''Pachycondyla''. They were not able to place some species with certainty, and left more than twenty species '' incertae sedis'' in ''Pachycondyla'', acknowledging that "this placement is undoubtedly incorrect". *'' Pachycondyla constricticeps'' Mackay & Mackay, 2010 *'' Pachycondyla crassinoda'' (Latreille, 1802) *'' Pachycondyla fuscoatra'' (Roger, 1861) *'' Pachycondyla harpax'' (Fabricius, 1804) *'' Pachycondyla impressa'' (Roger, 1861) *'' Pachycondyla inca'' E ...

Dorylinae
Dorylinae is an ant subfamily, with distributions in both the Old World and New World. Brady ''et al.'' (2014) synonymized the previous dorylomorph subfamilies (Aenictinae, Aenictogitoninae, Cerapachyinae, Ecitoninae, and Leptanilloidinae) under Dorylinae., while Borowiec (2016) reviewed and revised the genera, resurrecting many genera which had previously been merged. Dorylinae genera are suggested to have evolved sometime between , subsequently undergoing rapid adaptive radiation events during their early history.

Dacetini
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'' and ''Acromyrmex'', make up two of the genera. Their cultivars mostly come from the fungal tribe 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 illnesses. They are especially ...

Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy. The recurrent evolution of flight is a classic example, as flying insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas ''homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different traits. Convergent evolution is similar to paralle ...

Homology (biology)
In biology, homology is similarity due to shared ancestry between a pair of structures or genes in different taxa. A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure. Evolutionary biology explains homologous structures adapted to different purposes as the result of descent with modification from a common ancestor. The term was first applied to biology in a non-evolutionary context by the anatomist Richard Owen in 1843. Homology was later explained by Charles Darwin's theory of evolution in 1859, but had been observed before this, from Aristotle onwards, and it was explicitly analysed by Pierre Belon in 1555. In developmental biology, organs that developed in the embryo in the same manner and from similar origins, such as from matc ...

Strumigenys
''Strumigenys'' is a genus of ants in the subfamily Myrmicinae. Biology ''Strumigenys'' form small nests in soil, under or between rocks, or in and under logs or under cattle dung. Some species nest in association with other ants such as '' Bothriomyrmex mayri'' or '' Rhytidoponera metallica''. Although they are normally slow moving, they can run quickly when disturbed. ''S. xenos'' is a permanent social parasite, which forms no workers and lives in the nests of its host ''S. perplexa''. Most species specialize in the hunt of springtails, and the others eat other soft-bodied arthropods.Australian Ants OnlineGenus ''Strumigenys''/ref> Distribution ''Strumigenys'' is found throughout the tropics and subtropics. 18 species are known from Australia.

Formicinae
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development. Formicines retain some primitive features, such as the presence of cocoons around pupae, the presence of ocelli in workers, and little tendency toward reduction of palp or antennal segmentation in most species, except subterranean groups. Extreme modification of mandibles is rare, except in the genera '' Myrmoteras'' and '' Polyergus''. However, some members show considerable evolutionary advancement in behaviors such as slave-making and symbiosis with root-feeding hemipterans. Finally, all formicines have very reduced stings and enlarged venom reservoirs, with the venom gland, specialized (uniquely among ants) for the production of formic acid. All members of the Formicinae "have a one-segmented petiole in the form of a vertical scale". Identification Formicine ants have a single node-like or scale-like petiole (postpetiole entirely lacking) and the apex of th ...
