MODERN STATUS: junior synonym of Thysanoura Lattreille 1796; belongs to a non-accepted, paraphyletic taxon (Kluge 2000), which is most known under the junior name Apterygota Lang 1888.

COMMENT. The name Thysanura is often regarded to be an emendation of the name Thysanoura (see above), with the same authorship by Latreille (while Latreille always used is as Thysanoura). The name Thysanura is widely known, but was used for different taxa - see the table below. In upper line of this table number of letters "c" corresponds to number of hundreds species in each taxon. As ca be seen, the authors who transferred the name Thysanura from one taxon to another, transferred it not to a larger, but to a smaller part of the thaxon formerly called Thysanura.

Initially, the names Thysanoura Latreille 1796 and Thysanura Leach 1815 were attributed to an order, which united all primarily wingless Hexapoda - i.e. to a taxon, later named Apterygota. Later, for springtailes was established a separate order Collembola Lubbock 1873, and the order Thysanura sensu Lubbock 1873 began to match a taxon Cinura. Later, for two-tailed thysanurans was established a separate order Diplura, and the order Thysanura sensu Lameere 1895 & Borner 1904 began to match the taxon Triplura. Some modern authors use the name Thysanura in more narrow sense, understanding under it only Zygentoma, or only Microcoryphia.

Among the circumscriptional synonyms of the name Thysanura, the name Apterygota is distinctly the most known and can be used as valid one, contrary to the principle of priority.
