Zoology
Entognatha are ametabolous animals, similar to insects. Their mouthparts are entognathous, retracted within the head.
They are apterous, wingless.
Taxonomy
Apterygota were historically united in Thysanura and Apterygota.
They evolved independently from Insecta.
Insecta in the strict sense = Ectognatha = Hexapoda - Apterygota
Insecta = Dicondylia + Archaeognatha.
Animal Theory
One can treat Apterygota as part of Insecta. Then Insecta is treated in a broader sense and is similar to Hexapoda.
Orders

Diplura: two-tails.
