Anochetus Ghilianii
''Anochetus ghilianii'' is a species of ant of the subfamily Ponerinae, which is native to Morocco, and it also has a not confirmed status in Gibraltar and Spain, as scientists are not sure whether its native or exotic due having a very low area where it lives in the Iberian peninsula (Only found in the province of Cadiz in Spain). The species is monogynous, the queens of this species is ergatoid, meaning that it does not have wings. However, the males from the colony do have wings. The worker numbers can vary from having between 300 and 250 in early months of the year to just between 10 and 50 in the summer, thus the colonies are not very big and they are usually 20-30cm deep. How to identify This species is very easy to identify from other species, as there aren't other Ponerinae trap jaw ants species in Morocco and the Iberian Peninsula. Also, the other trap jaw ants in these countries are from the Strumigenys genus and have triangle heads instead of hexagonal heads. The ...

Maximilian Spinola
Maximilian Spinola ( it, Massimiliano Spinola; July 10, 1780 – November 12, 1857) was an Italian entomologist. Background Spinola was born in Pézenas, Hérault, France. The family of Spinola was of very long standing and had great wealth and power in Genoa. Maximilian Spinola was a descendant of the famous Spanish General Ambrogio Spinola, marqués de los Balbases (1569–1630) and much of his wealth derived from land held in Spain and South America. He was linked to Camillo Pallavicini. Research He received many insects from his properties in Spain and South America. He also made extensive, and expensive purchases especially of large showy tropical beetles and wasps. His entomological contributions were mainly in the orders Coleoptera, Hymenoptera and Hemiptera. Spinola made very important contributions to entomology, describing many taxa, especially in Spinola M. M., 1850.''Tavola sinottica dei generi spettanti alla classe degli insetti Arthroidignati, Hemiptera Lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ponerinae
Ponerinae is a subfamily of ants in the Poneromorph subfamilies group, with about 1,600 species in 47 extant genera, including ''Dinoponera gigantea'' - one of the world's largest species of ant. Mated workers have replaced the queen as the functional egg-layers in several species of ponerine ants. In such queenless species, the reproductive status of workers can only be determined through ovarian dissections. Description and identification They are most easily identified from other subfamilies by possessing a single-node petiole with a constriction before the second gastral segment. They are rare examples of stinging ants. In addition to the sting, they can also be characterized by a single segmented petiole and the constriction of the first and second segment of the gaster. They can also be identified by the shape of their head. Female workers have twelve segmented antennae, whereas male workers have 13 segmented antennae. Behavior These ants typically nest in soil, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ergatoid
An ergatoid (from Greek '' ergat-'', "worker" + ''-oid'', "like") is a permanently wingless reproductive adult ant or termite. The similar but somewhat ambiguous term ergatogyne refers to any intermediate form between workers and standard gynes. Ergatoid queens are distinct from other ergatogyne individuals in that they are morphologically consistent within a species and are always capable of mating, whereas inter caste individuals, another class of ergatogynes, often are not. Ergatoids can exhibit wide morphological differences between species, sometimes appearing almost identical to normal workers and other times being quite distinct from both workers and standard queens. In addition to morphological features, ergatoids among different species can exhibit a wide range of behaviors, with some ergatoids acting only as reproductives and others actively foraging. Ergatoid queens have developed among a large number of ant species, and their presence within colonies can often provide c ...

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.

Anochetus
''Anochetus'' is a genus of small, carnivorous ants found in the tropics and subtropics throughout the world. This genus is present in both the Old and New World and is certainly native to all continents except Antarctica and Europe. In Europe only a single species, ''Anochetus ghilianii'', has been found, and it is not certain it is native to its European range (Province of Cadiz and Gibraltar). However ''A. ghilianii'' is native to Morocco. ''Anochetus'' is of some note due to it being one of the relatively few genera that possess ''trap-jaws'', or specialized long mandibles that have a rapid closing mechanism. However, it is the only other genus, other than ''Odontomachus'' that uses the mandibles for predator evasion as well as prey capture.

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 ...
