Etymology. The species is named in honour of Dr Nicolae Onea, renowned specialist in birds from Brăila Museum Complex, Natural Sciences Section, as a sign of profound friendship and gratitude for all the spiritual help he offered to me.

Remarks. Campylaspis oneai sp. nov. resembles C. dumitrumurariui sp. nov. in having a similar sulcus and anterior transverse ridge. Campylaspis oneai differs from C. dumitrumurariui in: carapace with tubercles vs. smooth, maxilliped 3 and pereopod 1 with shorter basis and longer merus, pereopod 2 with robust vs. slender carpus, shorter uropods with 5 vs. 9 medial setae on endopod.
Distribution. Australia: NSW—east of Long Reef, at 174 m; NT—New Year Island, at 10 m depth.
