Stereomyrmex
''Stereomyrmex'' is a genus of myrmicine ants. Two of the described species are known from only a single worker, making this one of the rarest groups of ants in the world.Australian Ants OnlineGenus ''Stereomyrmex''/ref> Biology The single specimen of ''S. anderseni'' was caught in a pitfall trap, and nothing is known about its biology. Systematics ''Stereomyrmex'' is probably the sister taxon to '' Romblonella''. Closely related genera are '' Leptothorax'' and '' Cardiocondyla''. Description ''S. dispar'' is 3.2 mm long and black, with yellowish brown mandibles, antennae, legs and terminal segments of gaster. ''S. anderseni'' is only 2 mm long, has a very different petiolar and postpetiolar structure and is paler in color. Distribution ''S. dispar'' has been described from a single worker, taken in 1933 on Bellona Island, Solomon Islands; no other specimen has since been found, and it is unlikely that the species is truly endemic to Bellona.

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] |

Leptothorax
''Leptothorax'' is a genus of small ants with mainly Holarctic distributions. The genus is notable for its widespread social parasitism, i.e. they are dependent on the help of workers from other ant species during a part or the whole of their life cycles. Closely related genera are ''Cardiocondyla'', '' Stereomyrmex'' and '' Romblonella''.

Cardiocondyla
''Cardiocondyla'' is an Old World genus of ants in the subfamily Myrmicinae. Distribution Approximately 70 species are currently recognized as belonging to this genus, most of which are distributed in the Old World tropics and subtropics, but a few of which occur in the temperate zone. Some species are also found widely separated in North America and the Pacific Islands, as a result of human introduction. Description Several species of this genus have a striking male polymorphism, with both winged and wingless forms. These males differ not only in morphology, but also in reproductive tactics. Closely related genera are '' Leptothorax'', '' Stereomyrmex'' and '' Romblonella''. Outbreeding ''Cardiocondyla elegans'' worker ants transport young queen ants to alien nests to promote outbreeding.Vidal M, Königseder F, Giehr J, Schrempf A, Lucas C, Heinze J.

Psyche (entomological Journal)
''Psyche'' is a scientific journal of entomology which was established in 1874 by the Cambridge Entomological Club as a "journal for the publication of biological contributions upon Arthropoda from any competent person". The name of the journal is derived from the Ancient Greek word for butterfly. The journal has been published since 1874 (with gaps from 1886 to 1887, 1995 to 1999, and 2000 to 2007). In 2007 the Club transferred the journal to the Hindawi Publishing Corporation, and it became an open-access journal in 2008, with articles distributed online under the Creative Commons Attribution License. Almost all back issues were scanned and are available online as PDF files. History Samuel Hubbard Scudder proposed to start an "Organ of the Cambridge Entomological Club" at its fourth meeting. When ''Psyche'' began publication, its first editor was B. P. Mann. Its articles concentrated on general anatomy, biological entomology, and to set up a Bibliographic Record of all writin ...

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 ...
