Remarks . Procampylaspis corberai sp. nov. is closely related to P. poorei Petrescu, 2006 , having a slender maxilliped 3, pereopod 1 propodus longer than the carpus, pereopod 2 dactylus with plumose setae, endopod of uropod with 3 setae. It differs in having: 12 dorsal tubercles on the carapace instead three, first teeth of dactylus of maxilliped 2 of equal length, and a longer uropod peduncle. Distribution .
