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.

Malacostraca is the second largest of the six classes of pancrustaceans behind insects, containing about 40,000 living species, divided among 16 orders.Its members, the malacostracans, display a great diversity of body forms and include crabs, lobsters, spiny lobsters, crayfish, shrimp, krill, prawns, woodlice, amphipods, mantis shrimp, tongue-eating lice and many other less familiar animals.
The mandibulates are divided between the extant groups Myriapoda (millipedes & centipedes, among others) and Pancrustacea (including insects and crustaceans, among others). Molecular phylogenetic studies suggest that the living arthropods are related as shown in the cladogram below.
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').
Dala is estimated to be around 2 millimetres long extrapolating from partial specimens, with no preserved head in the holotype and only a fragmentary one in the paratype. . It has eight pairs of thoracic appendages forming a filter apparatus, four pairs of cephalic appendages, a large labrum and five ring-shaped abdominal segments, alongside a long furca on the posteriormost segme
