Reviewing some morphological evidence on Embioptera classification

Abstract

Several slow evolving characters are evaluated here with the main objective of reinforcing the higher classification of Em¬bioptera. An auditory chordotonal organ is described for the Order Embioptera where differences in shape and position ac¬cording to taxonomic group are observed. Through the use of ultrastructure analysis on both silk ejector and various types of leg setae are also depicted within a taxonomic framework. The correlation of the new traits and their different conditions are tested by using the current phylogeny of the order.
