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.
