 Holotype ♀, 3.44 mm, P.88216, Australia, NSW, north-east of Port Jackson, -33.68° 152.00°, 820–888 m, beam trawl, 11 Feb 1986, R. T. Springthorpe, FRV Kapala, K86-01-07, in AM. Paratypes: 1♀, P.65303; 1 subadult ♂, P.65557.   
 Etymology. The species is dedicated to the memory of Dr Igor Sienkiewicz (1907–2006), a brilliant specialist in Heteroptera, who worked for a short period of time but left unforgettable traces in the “Grigore Antipa” Museum (1956–1964) and in the Romanian history of science, as a sign of high gratitude for his moral and professional qualities.   
 Diagnosis. Carapace 0.5 body length, 2 lateral sulci delimited by 3 ridges; pereopod 2 dactylus 3 propodus length, with digitiform tip; uropodal peduncle 2 pleonite 6 length, 1.6 endopod length, exopod shorter than endopod, endopod with 3 setae on medial margin.   
 Description. Carapace 0.47 body length, 2.3 as long as high; 2 lateral sulci delimited by 3 ridges; pseudorostral lobes 0.3 carapace length, meeting in front of eyeless minute ocular lobe; tiny antennal notch (Fig. 33 A, B). — Antenna 1 peduncle article 1 0.85 rest of article’s length, with 1 simple seta; article 2 as long as article3, with1 simple seta; main flagellum with 3 articles, 0.7 peduncle apical article, accessory flagellum with 1 article; aesthetascs 2 main flagellum length (Fig. 33 C). — Maxilliped 2 basis fused with ischium, with plumose seta; merus with 1 plumose seta; carpus 2.8 merus length, with 1 simple seta; propodus 1.8 carpus length, with short tooth and 2 simple setae; short tridentate dactylar teeth equal in length (Fig. 33 D). — Maxilliped 3 basis 0.8 rest of article’s length, with 4 plumose setae and 1 robust tooth medially; merus, 4.5 ischium length, with 1 plumose and 5 simple setae; carpus 0.4 merus length, with 2 simple and 1 plumose seta; propodus 1.1 carpus length, with 2 pappose setae; dactylus 0.6 propodus length, with 3 simple setae; with exopod (Fig. 33 E). — Pereopod 1 basis 0.6 rest of article’s length, with 2 plumose setae; ischium with 1 plumose seta; ischium to propodus with serrate margins; merus 3.3 ischium length, with 2 simple and 3 plumose setae; carpus 0.8 merus length, with 3 simple and 3 plumose setae; propodus 0.8 carpus length, with 2 simple and 3 plumose setae; dactylus 0.7 propodus length, with 6 simple setae; with exopod (Fig. 33 F). — Pereopod 2 basis 0.6 rest of article’s length, with 1 simple and 2 plumose setae; merus 5 ischium length, with 2 simple setae; carpus 3 merus length, with 1 simple and 4 plumose setae; dactylus, 3 propodus length, with short digitiform tip, 9 simple setae and 1 terminal plumose seta; with exopod (Fig. 33 G). — Pereopods 3–5 with decreasing basis and increasing carpus length; pereopod 3 basis with 1 simple seta, plumose seta in pereopods 4 and 5; ischium and merus with 1 simple seta; carpus with 1 simple and 1 annulate seta; propodus with 1 annulate seta; dactylus with 1 annulate and 1 long simple terminal seta (Fig. 33 H–J). — Uropod peduncle 2 pleonite 6 length, 1.6 endopod length, with serrate margins; exopod 0.8 endopod length, with 2 simple setae and 1 terminal robust simple seta; endopod with 3 simple setae medially and 1 terminal robust seta longer than in endopod (Fig. 33 K).   
 Remarks. The new species is closely related to C. triplicata Hale, 1945 with similar ridges on carapace. Campylaspis sienkiewiczi sp. nov. differs with: small eyeless ocular lobe versus a large one, with 3 lenses; pereopod 2 dactylus with digitiform tip, absent in Hale’s species.   
 Distribution. Australia, widely distributed: NSW— northeast of Port Jackson, and Pittwater, at 5–888 m; and WA—North West Shelf, at 52 m depth.
