 Type material. Type material (holotype and paratypes) was not registered by NIWA in 2002. Type material appears to have been lost, see remarks. Neotype ovigerous female, NIWA 70506, 43.8363°S, 176.7092°E – 43.8330°S, 176.7127°E, 478–479 m, 5 April 2007 is hereby designated.   
 Material examined. 1 specimen, NIWA 13165, 45.2000°S, 171.8167°E, 860 m, 13 October 1965. 1 specimen, NIWA 46197, 42.7820°S, 176.7152°W – 42.7817°S, 176.7042°W, 1023–1026 m, 16 April 2007. 6 specimens, NIWA 70507, 43.5212°S, 178.6203°W – 43.5228°S, 178.6315°W, 424–425 m, 18 April 2007. 1 specimen, NIWA 70501, 44.1208°S, 174.8432°E – 44.1242°S, 174.8448°E, 512–513 m, 4 April 2007. 6 specimens, NIWA 46198, 42.9958°S, 178.9957°E – 42.9910°S, 179.0052°E, 520–530 m, 24 April 2007. 3 specimens, NIWA 70500, 42.9958°S, 178.9957°E – 42.9910°S, 179.0052°E, 520–530 m, 24 April 2007. 10 specimens, NIWA 46199, 43.5300°S, 178.5048°E – 43.5363°S, 178.5118°E, 346 m, 24 April 2007. 5 specimens, NIWA 70498, 42.9758°S, 177.1698°E – 42.9758°S, 177.1698°E, 376 m, 25 April 2007. 5 specimens, NIWA 70508, 43.7967°S, 175.3158°E – 43.8045°S, 175.3148°E, 418–422 m, 27 April 2007. 6 specimens, NIWA 70504, 43.8298°S, 176.7102°E – 43.8298°S, 176.7102°E, 479 m, 5 April 2007. 1 specimen, NIWA 81218, 43.8363°S, 176.7092°E – 43.8330°S, 176.7127°E, 478–479 m, 5 April 2007. 2 specimens, NIWA 70502, 44.0162°S, 178.5210°E – 44.0143°S, 178.5175°E, 769–771 m, 7 April 2007. 2 specimens, NIWA 70503, 44.0128°S, 178.5167°E – 44.0128°S, 178.5167°E, 764 m, 8 April 2007. 1 specimen, NIWA 70499, 43.9790°S, 179.6298°E – 43.9850°S, 179.6218°E, 529–530 m, 9 April 2007. 1 specimen, NIWA 70505, 43.9790°S, 179.6298°E – 43.9850°S, 179.6218°E, 529–530 m, 9 April 2007. 3 specimens, NIWA 46217, 40.8800°S, 170.8555°E – 40.8883°S, 170.8565°E, 529–534 m, 6 June 2007. 22 specimens, NIWA 46200, 40.8800°S, 170.8555°E – 40.8883°S, 170.8565°E, 529–534 m, 6 June 2007.   
 Diagnosis. Females and subadult males. Carapace with u-shaped arrangement of large tubercles dorsally, shape is open anteriorly, with scattered setae; pseudorostrum strongly dorsally directed. Carapace, pereonites and pleonites without few scattered red chromatophores. Pereonites 1–2 free only dorsally. Pereopod 2 dactylus normal, terminal seta long. Uropod peduncles 2.0 times length of pleonite 6. Male. Adult unknown.   
 Remarks. Campylaspis rex is unique within the New Zealand Campylaspis fauna for the combination of the pattern of a single continuous line of large tubercles dorsally, dorsally directed pseudorostrum and no sulcus on the carapace. Campylaspis macrosulcata is the only other species in the New Zealand fauna with the uropod exopod longer than the endopod; however, C. macrosulcata has a distinct deep sulcus bounded with carinae on the carapace and no tubercles, while C. rex has no sulcus and large tubercles dorsally on the carapace. This species is readily identifiable on the basis of the original description.   
The type material, holotype and paratypes, was returned to NIWA at the time of publication, in 2002. However, the collection manager at the time refused to register type material until after the paper was published, thus the material was not registered before publication, and no registration numbers could be included in the original publication. Communication with the current collections staff at NIWA indicates that the type material for this species was never registered, and despite searching both the type and general collections cannot be found. In addition, the laboratory in which the original material was described, the Darling Marine Center, has been searched for this type material and it has not been found. With the availability of material from the same region in good shape, examined by one of the original authors, a neotype is thus designated. As both the holotype and all paratypes have been lost, for the name to remain valid, new type material must be declared.
