These ants are large, measuring . During the time of its discovery, Douglas and Brown announced ''M. inquilina'' as the first social parasite among the primitive subfamilies, and today it is one of the two known ''Myrmecia'' species to have no worker caste. Two host species are known, ''Myrmecia nigriceps'' and ''Myrmecia vindex''. Aggression between ''M. inquilina'' and its host species does not occur, and colonies may only produce ''M. inquilina'' brood months after the inquiline queens begin to lay their eggs. Queens eat the colony brood or trophic eggs, and other ''Myrmecia'' species may kill ''M. inquilina'' queens if they reject them. Due to its restricted distribution and threats to its habitat, the ant is "vulnerable" according to the IUCN Red List. ==Taxonomy== Before the discovery of ''M. inquilina'', scientists believed that parasitic ants did not exist in the primitive ant subfamilies and were only known in Dolichoderinae, Formicinae and Myrmicinae; many authors believed that primitive ants lacked a certain trait that would prevent parasitic ants from forming, but the discovery of ''M. inquilina'' now hints possible parasitic lifeforms in Ponerinae and some army ants. Brown collected the first specimens in 1955 from large fallen trees in Western Australia, and it was officially announced as the first parasitic ant among the primitive subfamilies in 1956. In 1959, Australian naturalist Athol Douglas and American entomologist William Brown Jr. provided the first description of the ant in an ''Insectes Sociaux'' journal article. Its specific epithet ''inquilina'' derives from the word ''inquilinus'', meaning "tenant". This name references the parasitic nature of the species, living inside a colony as a "guest" of another species. Brown discovered the holotype female from an ''M. vindex'' nest on 23 March 1955 northwest from Wagin at Badjanning Rocks, Western Australia. The specimen is currently housed in the Western Australian Museum in Perth.〔 Two dealated paratype females were also collected with the holotype, looking very similar to each other except for the mandibles and colouration. The mandibular dentition varies among the three, and one of the paratypes is darker than the holotype. In 1991, a published journal reviewing the species groups assigned ''M. inquilina'' to the ''M. cephalotes'' species group. However, entomologists placed it in the ''M. gulosa'' species group one month after placing it in the ''M. cephalotes'' species group. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Myrmecia inquilina」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
