Two new Prionospio species—Prionospio solisi sp. nov. and Prionospio nonatoi sp. nov. and a new Laubieriellus species—Laubieriellus decapitata sp. nov. are described from Espírito Santo Basin, Southeast Brazil. For both Prionospio species, branchial pattern differed from the genus diagnosis, which is therefore emended. For Laubieriellus, a new species is described, and attention is drawn to the notch in the ventral crests, a structure that holds taxonomic value.
