MODERN STATUS: non-valid name (see COMMENT); the valid name is Triplura; belongs to a taxon which is most probably holophyletic).
COMMENT. Hennig (1953) wrongly used the name Ectognatha for a taxon which next year was named Amyocerata. Many authors followed him, because thought that Hennig was the author of the name Ectognatha. Actually, the name Ectognatha was widely used in text-books of the 1st half of XXth century (Escherich 1914, Börner 1920, Schwanwitsch 1949, Kuznetsov 1951 et al.), and Hennig transferred this from a small (about 1000 species) taxon of wingless insects to a huge (more that 1000000 species) taxon which unites true Ectognatha with Pterygota.
