i wouldnt say they are crustacean,sbut a sister group to crustecea. its like saying PYCOGNIDS(SEA SPIDERs are related to actual spiders), they had 500million years of seperate lineages from each other. even somewhat closer peccaries and pigs, arnt closely related, but they are sister to each other on the family scale.
It is not a “sister” group because some crustaceans are more related to insects than to other crustaceans; check the family trees here. The accurate way to say this is that Hexapoda is clade within Pancrustacea, and that “crustaceans” is a paraphyletic group composed of all Pancrustacea minus the ones belonging to Hexapoda.
