Pancrustacea is the clade that comprises all crustaceans, and all hexapods (insects and relatives).[2] This grouping is contrary to the Atelocerata hypothesis, in which Hexapoda and Myriapoda are sister taxa, and Crustacea are only more distantly related. As of 2010, the Pancrustacea taxon was considered well accepted, with most studies recovering Hexapoda within Crustacea.[3] The clade has also been called Tetraconata, referring to having four cone cells in the ommatidia.[4] The term "Tetraconata" is preferred by some scientists in order to avoid confusion with the use of "pan-" to indicate a clade that includes a crown group and all of its stem group representatives.[5]
