sp. nov. and Prionospio nonatoi
sp. nov. and a new Laubieriellus
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.
