Grammoplites vittatus (Valenciennes), often previously overlooked by authors or regarded as a junior synonym of G. scaber (Linnaeus), is shown here to be a valid species. It has more gill rakers (7-8) then G. scaber and G. knappi (usually 6) and a narrower interorbital width than G. scaber. A key to the species of Grammoplites Fowler is given.
