Hexapoda: tracheate arthropods with head, thorax and abdomen distinct, and only six legs in the adult stage: the true insects.
We find him supporting his comparison of the three anterior pairs of legs in _Julus_ to the three pairs of legs in insects by an argument drawn from embryology; for only the first three pairs of feet are present in _Julus_ at birth (Degeer), "an observation, which, together with their position, should cause them to be considered as the representatives of the six thoracic feet of Hexapoda" (p. 44).
He is quite clear that the maxillipedes of Crustacea are the homologues of the feet of Hexapoda.
Hexapoda refers to all insects and their six-legged relatives.
Our results strongly support Pancrustacea (Hexapoda plus Crustacea) but also strongly favour the traditional morphology-based Mandibulata
Now, after analyzing 62 shared genetic sequences across all the arthropods, the researchers are putting the strange shrimp together with the six-legged insects, Hexapoda, to form a new group they dubbed Miracrustacea, or "surprising crustaceans."
Within the insect group Hexapoda, the good news for taxonomists who have grouped insects according to body shape and features is that they were pretty much on the mark, Shultz added.
The discovery that terrestrial insects (Hexapoda) are more closely related to aquatic Crustacea than to the terrestrial centipedes and millipedes
In addition to Hexapoda, Pancrustacea includes three major extant lineages of 'crustaceans', each spanning a significant range of morphological disparity.
Finally, within Pancrustacea we identify Xenocarida as the long-sought sister group to the Hexapoda, a result confirming that 'crustaceans' are not monophyletic.
