MODERN STATUS: the valid (while far not the oldest!), generally accepted name of a non-recognized, paraphyletic taxon uniting Entognatha and Triplura (Kluge 2000).
COMMENT. The name Apterygota Lang 1888 is far not the oldest circumscriptional name for this taxon. The older name Thysanoura Latreille 1796 and its emendation Thysanura Leach 1815 were widely used in the past, but later the name Thysanura was often used in other meanings, and in since 1873 was not used in its original meaning (see Thysanura). The names Seticaudes, Nematoura and Monomorphes never were in wide usage. The name Apterygogenea Brauer 1885 is well known, however its later emendation Apterygota is in more wide use. As the name Apterygota is distinctly the most known among its circumscriptional synonyms, it can be used as valid one, contrary to the principle of priority. Besides Triplura, Diplura and Collembola, to Apterygota belong also Protura, which in 1888 were not discovered yet.
