Holotype subadult ♀, 7.08 mm, P.64752, Coral Sea , northeastern continental slope [of Australia], -18.18° 147.53°, 472–879 m, 26 Aug 1988, P.A. Hutchings, RV Franklin, FR 0688-21 or 22 | FRO688, in AM.

Etymology. The species id dedicated to the memory of Prof. Dr Mircea Paucă (1903–1988), distinguished geologist and palaeontologist, who worked at the “Grigore Antipa” Museum during the period of Antipa’s life, the only one who left memories regarding that period (1934–1944), as a sign of high posthumous gratitude for his moral and professional qualities.

Diagnosis. Carapace 0.42 body length, with rows of tubercles; maxilliped 2 merus with 2 and carpus with 3 tubercles, propodus with 1 tooth; uropodal peduncle 2.5 pleonite 6 length; 1.5 endopod length; endopod with 4 simple setae medially.

Description. Carapace 0.42 body length, 1.6 longer than high, with rows of acute tubercles, each tubercle surrounded by small plates; pseudorostrum 0.2 carapace length; anterior and anterolateral margins serrated; antennal notch small ( Fig. 29 A, B View Figure 29 ). — Pereonites and pleonites with dorsal teeth. — Antenna 1 peduncle article 1 1.85 rest of article’s length; article 2 1.1 article 3 length; main flagellum 1.3 peduncle distal article; accessory flagellum with 1 article; aesthetascs 1.4 main flagellum length ( Fig. 29 C View Figure 29 ). — Maxilliped 2 basis with 1 plumose seta medially; merus 2.2 ischium length, with 2 tubercles and 1 plumose seta; carpus with 3 teeth and 2 simple setae; propodus 0.9 carpus length, with 1 tooth and short stout seta little longer than dactylar teeth ( Fig. 29 D View Figure 29 ). — Maxilliped 3 basis 0.51 rest of article’s length, with 5 simple and 8 plumose setae; merus 3.5 ischium length, with 1 tooth, 5 plumose and 2 plumose setae; carpus 0.45 merus length, with 1 simple, 1 plumose and 1 pappose seta; propodus 1.2 carpus length, with 1 plumose and 3 pappose setae; dactylus 0.7 propodus length, with 3 simple setae; basis, merus to dactylus with serrate margins; with exopod ( Fig. 29 E View Figure 29 ). — Pereopod 1 basis 0.47 pereopod length, with 3 plumose setae, basis to propodus with serrate margins; ischium with 1 plumose seta; merus 2.2 ischium length, with 3 plumose and 2 simple setae; carpus 1.3 merus length, with 2 plumose and 5 simple setae; propodus 0.9 carpus length, with 3 simple and 2 plumose setae; dactylus 0.4 propodus length, with 6 simple setae; with exopod ( Fig. 29 F View Figure 29 ). — Pereopod 2 basis 0.4 of total length; basis to carpus with serrate margins; ischium with 1 plumose seta; merus 3 ischium length, with 2 simple and 1 plumose seta; carpus 2.3 merus length, with 1 plumose and 4 simple setae; dactylus 4.3 propodus length, with a rounded tip and with 7 simple; with exopod ( Fig. 29 G, H View Figure 29 ). — Pereopods 3–5 with decreasing basis and increasing carpus; dactylus fused with terminal simple seta; with simple, plumose and annulate setae ( Fig. 29 I–K View Figure 29 ). — Uropod peduncle 2.5 pleonite 6 length, 1.5 endopod length; entire uropod with serrate margins; exopod broken; endopod with 4 simple setae medially, 1 terminal simple seta ( Fig. 29 L View Figure 29 ).

Remarks. Campylaspis paucai sp. nov. resembles C. panai sp. nov. in having carapace tubercles, an eyeless ocular lobe, maxilliped 2 with short setae on the propodus. The new species differs from C. panai in: the integument of the carapace with small tubercles vs. small and large tubercles in C. panai ; the spiny pereonites and pleonites in C. paucai vs. smooth pereonites and pleonites; Antenna 1 peduncle basal article longer than in. C. panai ; maxilliped 2 with basis separate from ischium; ischium with 2 teeth vs. not teeth in C. panai , carpsu with 2 teeth vs. 1 tooth; maxilliped 3 with slender merus in C. paucai vs. large articles in C. panai ; pereopods 3, 4 with 4 plumose setae on basis in C. paucai vs. 1 plumose seta; uropod endopod with 4 setae in C. paucai vs. endopod with 3 setae.

Distribution. Coral Sea: from 472–879 m depth.
