Eutetramorium
''Eutetramorium'' is a small genus of ants within the subfamily Myrmicinae. To date it contains three species found in Madagascar and Comoros. Species *'' Eutetramorium mocquerysi'' Emery 1899 – Madagascar *'' Eutetramorium monticellii'' Emery 1899 – Comoros *'' Eutetramorium parvum'' Bolton & Fisher, 2014 – Madagascar Description The queen is extremely ergatoid in ''E. mocquerysi'', alate in ''E. monticellii''. In ''E. parvum'' a normal dealate queen is present in the type-series, but there is also a specimen that may be an ergatoid or a worker-queen intercaste, or possibly merely an oversized worker. Males are known only for ''E. mocquerysi'', where it is smaller than conspecific workers. Taxonomy This small genus was established by Emery (1899) for two conspicuous, large, darkly coloured Madagascan species that superficially resemble ''Tetramorium''. Initially, Emery (1912, 1914) was of the opinion that the genus was referable to the tribe Myrmecinini, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royidris
''Royidris'' is a Malagasy genus of ants in the subfamily Myrmicinae. Described in 2014, the genus contains 15 species endemic to Madagascar. Description Queens are known for ''R. admixta'', ''R. diminuta'', ''R. notorthotenes'', ''R. peregrina'', and ''R. shuckardi'', plus two unassociated forms. Alate when virgin, considerably larger than the worker. Males are known only for ''R. notorthotenes'' and ''R. peregrina''. About the same size as the worker or slightly smaller, much smaller than the queen. Taxonomy The species included in this genus exhibit a habitus that is convergent on some groups of ''Monomorium''.

Vitsika
''Vitsika'' is a Malagasy genus of ants in the subfamily Myrmicinae. Described in 2014, the genus contains 14 species. Description Queens are known for all species except ''V. obscura''. The queens may be alate or ergatoid, or both forms may occur within a single species. It is possible that all species will be found to produce both ergatoids and alates when the species are better represented in collections. Two species (''V. manifesta'', ''V. suspicax'') exhibit morphological intermediates between alate and ergatoid forms, and two species (''V. acclivitas'' and ''V. crebra'') appear to be polygynous Polygyny (; from Neoclassical Greek πολυγυνία (); ) is the most common and accepted form of polygamy around the world, entailing the marriage of a man with several women. Incidence Polygyny is more widespread in Africa than in any .... Worker-associated males are known for ''V. crebra'', ''V. breviscapa'' and ''V. labes''. In addition, the males of three othe ...

Malagidris
''Malagidris'' is a Malagasy genus of ants in the subfamily Myrmicinae. Described in 2014, the genus contains six species. Species * '' Malagidris alperti'' Bolton & Fisher, 2014 * '' Malagidris belti'' (Forel, 1895) * '' Malagidris dulcis'' Bolton & Fisher, 2014 * '' Malagidris galokoa'' Bolton & Fisher, 2014 * '' Malagidris jugum'' Bolton & Fisher, 2014 * '' Malagidris sofina'' Bolton & Fisher, 2014 Taxonomy The type species of this genus, ''M. belti'' ( Forel, 1895), has had a moderately varied taxonomic history. It was originally described in the genus ''Aphaenogaster'' (Mayr, 1853), even though Forel remarked on its 3-segmented antennal club, rather than 4 as is usual in that genus. This character, coupled with the presence of angulate humeri and a queen with a depressed mesosoma, caused Emery (1915) to exclude ''M. belti'' from ''Aphaenogaster'' and transfer it to ''Atopula'' (Emery, 1912). Forel (1917) decided that ''Atopula'' was artificial, "composed of disparate spec ... [...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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
