Acanthognathus (fish)
''Acanthognathus'' is a genus of ants that are found in tropical Central and South America.Brown, W. L., Jr., & W. W. Kempf (1969). ''A Revision of the Neotropical Dacetine Ant Genus Acanthognathus (Hymenoptera: Formicidae.'' Psyche 76(2): 87-109. There are 7 living species and 1 extinct species, ''Acanthognathus poinari'', known only from fossil records. Description They are reddish in colour and have long trap-jaws that can be compared to those of '' Odontomachus''. These predatory ants live in small colonies that typically consist of less than 30 adults. Acanthognathus has large, line-shaped jaws, each with an apical fork of 3 spiniform teeth that interlock when fully closed; Preapical dentition sometimes present but often absent. Jaws open to 170 degrees or more. Basal process of mandible a long curved spur that is minutely bifurcated apically; when the mandibles are fully closed, the basal processes intersect and are ventral to the labrum and at the apex of the labio-maxil ...

Nemesiidae
Nemesiidae, also known as funnel-web trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae". Description Nemesiidae are relatively large spiders with robust legs and a body that is nearly three times as long as it is wide. They are darkly colored, brown to black, though some have silvery hairs on their carapace. '' Atmetochilus'' females can grow over long. They live in burrows, often with a hinged trapdoor. This door is pushed up while the spider waits for passing prey. They rarely leave their burrows, catching prey and withdrawing as quickly as possible. Some of these burrows have a side tubes, but it is not certain whether ''Sinopesa'' builds burrows at all. Genera , the World Spider Catalog accepts the following genera: *'' Amblyocarenum'' Simon, 1892 *''Brachythele'' Ausserer, 1871 — Europe, Cyprus *''Calisoga'' Chamberli ...

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] |
Ant Genera
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists. Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens" (gynes). The colonies are described as superorganisms because the ants a ...

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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
