 Remarks. Campylaspis dumitrumurariui sp. nov. resembles C. edenensis Petrescu, 2006 and C. gherasimi sp. nov. by having a lateral sulcus with a transverse ridge on the anterior part. It differs from C. edenensis in: little shorter sulcus, shorter merus of maxilliped 3, pereopod 2 dactylus without a digitiform tip and a longer uropod with more setae on its endopod. Campylaspis dumitrumurariui differs from C. gherasimi in: smaller carapace, maxilliped 3 merus and carpus shorter and slender, pereopod 1 with longer basis and shorter rest of articles, dactylus of pereopod 2 with simple lateral setae versus plumose ones, longer uropod with more setae on endopod, 9 vs. 6.   
 Distribution. Australia: NSW—north east of Long Reef, at 466 m depth.
