Description. Carapace 0.4 body length; 1.8 as long as high; large lateral sulcus, 0.85 of carapace length, almost straight dorsally; ocular lobe with 3 large lenses; pseudorostrum 0.38 carapace length ( Fig. 3 A ). — Maxilliped 3 with large basis, 0.68 rest of article’s length, with 5 plumose setae; merus 2.7 ischium length, with 3 plumose setae; carpus 0.37 merus length, with 1 plumose seta; propodus 1.1 carpus length; dactylus 0.33 propodus length, with 4 terminal simple setae; with exopod ( Fig. 3 B ). — Pereopod 1 basis 0.8 rest of article’s length, with 2 plumose setae; merus, 2nd longest article, 2.25 ischium length, with 4 plumose and 2 simple setae; carpus 0.8 merus length, with 2 plumose setae; propodus 0.7 carpus length; dactylus 0.8 propodus length, with 4 terminal simple setae; with exopod ( Fig. 3 C ). — Pereopod 2 basis 0.7 rest of article’s length, with 2 plumose setae; merus 0.4 ischium length, with 2 plumose setae; carpus 1.5 merus length, with 1 simple and 4 plumose setae; dactylus 2.2 propodus length, with 11 simple setae and digitiform tip; with exopod ( Fig. 3 D ). — Pereopods 3, 4 with decreasing basis and increasing carpus; basis to merus with 1 simple seta, carpus with 2 annulate setae, propodus with 1 annulate seta; dactylus with 1 terminal simple seta; with exopods ( Figs 3 E, F ). — Pereopod 5 basis 0.6 pereopod 4 basis; basis to merus with 1 simple seta; merus 2 ischium length; carpus 1.2 merus length, with 2 annulate setae; propodus 0.16 carpus length, with 1 annulate seta; dactylus 0.6 propodus length with 1 terminal simple seta ( Fig. 3 G ). — Uropod peduncle 2.5 pleonite 6 length, 2.5 endopod length with 5 plumose setae and serrate margins; endopod 1.4 exopod length; exopod with 2 simple setae; endopod with 9 microserrate and 1 terminal simple seta ( Fig. 3 H ).

Remarks. Campylaspis adelae sp. nov. is closely related to C. minor Hale, 1945 , but with maxilliped 3 with 3 vs. 2 plumose setae on the basis; no setae on the ischium and merus vs. numerous short setae; dactylus with 4 vs. 2 terminal setae on dactylus; pereopod 1 with 2 plumose setae on basis vs. none, dactylus with 3 simple terminal short setae vs. 2 plumose long and 1 simple short seta; pereopod 2 with 2 setae on basis vs. none, dactylus with simple setae vs. plumose setae; 1.5 longer uropodal peduncle.
