Exopterygota
A traditional classification in zoology, but is invalid. The correct classification is Neoptera. Although Exopterygota is still used by some as a subdivision within the Neoptera, for the moment ITIS is not implementing this.
Traditionally, Exopterygota was a division (17 orders) of the class Insecta characterized by incomplete metamorphosis and resemblance of the juvenile and the adult.
