Kluge 2010 BioNomina Dual-Nom :

Today the taxon consisting of Triplura and Pterygota is often called “Ectognatha”. At some point, the authorship of the name Ectognatha was misattributed to Hennig (see, e.g., Kristensen 1995), but Hennig could pick it up from textbooks. Originally, the name Ectognatha Stummer-Traunfels 1891 was proposed for the taxon of wingless insects, later named Triplura Ewing 1942.

Hennig (1953) used the name “Ectognatha” to refer to a taxon combining the original Ectognatha (i.e., Triplura) with the Pterygota, and thus changed the circumscription to include all winged insects. Some workers apply circumscriptional principles loosely and consider that a non-typified name can be shared by taxa of nearly the same circumscription. In this case, though, the difference was enormous. Originally, the name Ectognatha was applied to triplurans to emphasize their difference from wingless insects with recessed mouthparts, i.e., Collembola and Diplura. This name sounds odd, though, being applied to insects with all kinds of mouthparts, including completely hidden ones, like in sucking lice.

For the taxon consisting of Triplura + Pterygota, some authors (e.g., Handschin 1958) used the name “Insecta”, whose original circumscription also does not fit this taxon.

In circumscriptional nomenclature, the correct name for Triplura + Pterygota is Amyocerata Remington 1955. Ectognathata Boudreaux 1979 is its junior circumscriptional synonym.

Using the names Ectognatha and Insecta instead of Amyocerata causes great confusion, when a statement about polyphyly of Hexapoda appeared from nothing (Kluge 1996a, 1999b, 2000).
