Allotriocarida

Allotriocarida is a clade of Pancrustacea, containing Hexapoda (all insects, springtails & their close relatives). It also contains three non-hexapod classes: Remipedia (blind, venomous crustaceans), Cephalocarida (translucent aquatic detrivores), and Branchiopoda (freshwater, non-decapod 'shrimp'). Newer studies also relocate Copepoda, which traditionally has belonged to the multicrustaceans, to the Allotriocarida.

Allotriocarida is one of three major clades within Pancrustacea, being most closely related to its sister clade Multicrustacea (crabs, lobsters, barnacles, etc), and more distantly related to the superclass Oligostraca (seed shrimp, fish lice, and tongue worms).
