However, the competing hypothesis — that Crustacea and Hexapoda form a monophyletic group, the Pancrustacea , to which the Myriapoda are the closest relatives — has support from molecular and fossil evidence. The distribution in this summary table is based on all the information available. Hexapods are characterized by the presence of a head, thorax, and abdomen, constituting three tagma.
