Castianeira Bartholini
''Castianeira'' is a genus of ant-like corinnid sac spiders first described by Eugen von Keyserling in 1879. They are found in Eurasia, Africa, and the Americas, but are absent from Australia. Twenty-six species are native to North America, and at least twice as many are native to Mexico and Central America. Description Spiders of this genus have eight eyes in two procurved rows, the upper row slightly wider than the lower row. This distinguishes them from species of '' Micaria'' that almost always have straight rows of eyes. The opisthosoma is not constricted, and has an elongate to oval shape to mimic that of ants. In addition to the ant-like coloration, the abdomen has white scale-like setae. The rear pair of legs are the longest, and the front pair are second longest. Mimicry Some species mimic specific groups of ants, while others only have generic body modifications to look more ant-like, such as an elongated body or a carapace pattern that creates the illusion of a ...

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...

Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis''. He published his first important work in 1796 (), and was eventually employed by the . His foresighted work on arthropod systematics and taxonomy gained him respect and accolades, including being asked to write the volume on arthropods for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive, then in the province of Limousin, as the illegitimate child of Jean Joseph Sahuguet d'Amarzit, général ...

Odontomachus
''Odontomachus'' is a genus of ants commonly called trap-jaw ants found in the tropics and subtropics throughout the world. Overview Commonly known as trap-jaw ants, species in ''Odontomachus'' have a pair of large, straight mandibles capable of opening 180°. These jaws are locked in place by an internal mechanism, and can snap shut on prey or objects when sensory hairs on the inside of the mandibles are touched. The mandibles are powerful and fast, giving the ant its common name. The mandibles either kill or maim the prey, allowing the ant to bring it back to the nest. ''Odontomachus'' ants can simply lock and snap their jaws again if one bite is not enough, or to cut off bits of larger food. The mandibles also permit slow and fine movements for other tasks such as nest building and care of larvae. The ants were also observed to use their jaws as a catapult to eject intruders or fling themselves backwards to escape a threat. The larvae of trap-jaw ants are remarkable in b ...

Atta (genus)
''Atta'' is a genus of New World ants of the subfamily Myrmicinae. It contains at least 17 known species. ''Atta'' leaf-cutter ants are relatively large, rusty red or brown in colour, and have a spiny body and long legs. The three main castes within a nest are the queen, worker, and soldier. Only the queens and males have wings (alate), and these ants are also known as reproductives or swarmers. Although most of the ants in the nest are female, only the queens produce eggs. Queens are usually over long. Overview Ants of the genus ''Atta'' are leafcutter ants that comprise one of the two genera of leafcutting ants within the tribe Attini, along with ''Acromyrmex''. They have no sting, thus inject no venom, although they are known as strong biters. ''Atta'' spp. exhibit a high degree of polymorphism, with four castes being present in established colonies: minims (or garden ants), minors, mediae, and majors (also called soldiers or dinergates). Their immature development underg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pachycondyla
''Pachycondyla'' is a Ponerinae, 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. ''Pachycondyla eocenica, P. eocenica'' and ''Pachycondyla lutzi, 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 impres ...
