Diagnosis. Carapace 0.44 body length, with small acute tubercles interspersed with pits, 1 larger pair of tubercles on basis frontal lobe; pereon and pleon with dorsal and lateral small teeth; maxilliped 2 propodus with 1 medial tooth; pereopod 2 dactylus 3.3 propodus length, with pedunculate tip; uropodal peduncle 2 pleonite 6 length, 2.75 endopod length; endopod with 6 simple setae medially.

Description. Carapace 0.44 body length, 1.5 longer than high; with small acute tubercles and pits, 1 pair of larger tubercles on basis of frontal lobe; pseudorostrum 0.3 carapace length, meeting in front of ocular lobe; ocular lobe without lenses; antennal notch present; anterolateral margin serrated ( Fig. 23 A, B ). — Pereon and pleon with dorsal and lateral denticles. — Maxilliped 2 basis fused with ischium, 1 plumose seta medially; merus with 1 plumose seta; carpus 1.5 merus length, with 1 tooth and 2 simple setae medially; propodus with 1 medial tooth and 1 robust seta, as long as 3 denticles of dactylus ( Fig. 23 C ). — Maxilliped 3 basis 1.3 rest of article’s length, with 3 simple and 7 plumose setae; large merus, 4.6 ischium length, with strong serrated margins, 3 simple and 2 plumose setae; carpus 0.7 merus length, with serrated margins, 1 plumose and 6 simple setae; propodus 0.5 carpus length, with 1 plumose and 2 pappose setae; dactylus 0.6 propodus length, with 3 simple setae; with exopod ( Fig. 23 D ). — Pereopod 1 robust basis 0.8 rest of article’s length, serrated medially with 5 plumose setae; merus 4.3 ischium length, with strong teeth, with 10 plumose setae; carpus 1.6 propodus length, serrated margins with 1 pappose and 4 simple setae; propodus 2 dactylus length, with 3 simple and 3 pappose setae; dactylus 0.5 propodus length, with 2 simple and 3 pappose setae; with exopod ( Fig. 23 E ). — Pereopod 2 basis 0.3 pereopod length; merus 6 ischium length, with 1 long simple seta; carpus 2.75 propodus length, with 2 simple setae; dactylus 3.3 propodus length, with digitiform tip; with exopod ( Fig. 23 F ). — Pereopods 3–5 with decreasing basis and increasing carpus length; ischium and merus with 1 simple seta; carpus and propodus with 1 annulate seta; dactylus with terminal simple seta ( Fig. 23 G-I). — Uropod peduncle 2 pleonite 6 length, 2.75 endopod length, serrate margins; exopod 0.85 endopod length, with 2 simple setae; endopod with 6 simple setae medially and 1 terminal simple seta ( Fig. 23 J )

Remarks. Campylaspis mioarae sp. nov. is closely related to C. marinescui sp. nov. by the carapace having tubercles; maxilliped 2 with one tooth on the propodus, as long as the dactylar teeth. Campylaspis mioarae sp. nov. differs with: carapace with acute tubercles with pit; maxilliped 3 with larger articles, without excavation on inner margin of merus, dactylus of pereopod 2 with a digitiform tip, uropod with 6 versus 4 setae on endopod.

Distribution. Australia: NSW—east of Long Reef, at 174 m depth.
