 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.

 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.
