Etymology. The species is named normani in honor of Norman S. Jones, in recognition of his work on the New Zealand cumacean fauna.

Remarks. Campylaspis normani is most likely to be confused with C. apheles and C. rufus . In C. normani there is a weak but definite sulcus on the carapace, while in C. apheles and C. rufus there is no sulcus. In addition, in the female C. normani there are rudimentary exopods on pereopods 3–4, while in both C. apheles and C. rufus the female is entirely without exopods on pereopods 3–4.
