Description . Carapace , 0.56 body length, 1.87 as long as high, 1.27 as long as wide, upper part of carapace granular; 1 pair of transversal dorsal ridges on basis of frontal lobe; 1 dorsal carina between basis of frontal lobe towards posterior extremity; 2 lateral sulci, 0.86 carapace length; pseudorostrum 0.3 carapace length; ocular lobe without lenses; smooth ventral margin ( Fig. 24 A, B ). — Antenna 1 peduncle article 1 0.68 rest of article’s length, with 1 simple and 1 pappose seta; article 2 as long as article 3; main flagellum 1.29 article 3 length, accessory flagellum with 1 article; aesthetascs 0.7 main flagellum length ( Fig. 24 C ). — Maxilliped 3 basis 0.71 rest of article’s length, with 5 plumose setae; merus to dactylus with serrate margins; merus 2.69 ischium length, with 1 plumose and 10 simple setae; carpus 1.71 propodus length, with 2 teeth, 2 plumose and 4 simple setae; propodus 0.63 dactylus length, with 2 pappose setae; dactylus 2 propodus length, with 3 terminal setae; with exopod ( Fig. 24 D ). — Pereopod 1 basis 0.7 rest of article’s length, with 1 plumose and 2 pappose setae; ischium with 2 pappose setae; merus 9 ischium length, with 10 pappose setae; carpus 0.27 merus length, with 2 simple and 5 pappose setae; propodus as long as carpus, with 3 simple and 4 pappose setae; dactylus 0.2 propodus length, with 3 simple and 2 pappose setae; with exopod ( Fig. 24 E ). — Pereopod 2 basis 0.63 rest of article’s length, with 3 pappose and 2 simple setae; ischium with 1 pappose seta; merus 2 ischium length, with 1 tooth, 1 simple and 1 pappose seta; carpus 1.03 merus length, with 4 simple and 6 pappose setae; propodus with 1 simple seta; dactylus 3.2 propodus length, with digitiform tip and 12 simple setae; with exopod ( Fig. 24 F ). — Pereopods 3–5 with decreasing basis and increasing carpus length; pereopods 3 and 5 with basis to merus with 1 plumose seta, pereopod 4 ischium and merus with 1 plumose seta; dactylus fused with terminal robust seta ( Fig. 24 G-I). — Uropod peduncle 2.72 pleonite 6 length, 2 endopod length, with 9 long simple setae interspersed with shorter setae; exopod as long as endopod, with 3 simple and 1 terminal microserrate robust seta; endopod with 4 microserrate short setae and 1 terminal robust microserrate seta ( Fig. 24 J ). Remarks . The new species is closely related to C. sculptaspinosa Gerken, 2012 from New Zealand , also with two parallel sulci, but with four setae on medial margin of uropodal endopod versus three, maxilliped 3 merus larger and propodus shorter than dactylus, dactylus of 2nd pereopod with shorter setae. Distribution . Australia : WA—North West Shelf, at 43 m depth.
