An order of minute white wingless insects with slender bodies. They lack eyes and antennae, using the first pair of legs as sensory organs.
- ‘Hexapoda (Insecta sensu lato) includes four groups: Protura, Collembola, Diplura, and Insecta sensu stricto (with the latter containing Microcoryphia or Archeognatha, Zygentoma, and the pterygote insects).’
- ‘There are huge gaps in the early fossil record, since several basal hexapod groups have not been found at all in the Paleozoic: Protura, Diplura, and Thysanura.’
Modern Latin (plural), from Greek prōtos first, primitive.
