Abstract. All earlier reports of Platyrhacus marginellus Silvestri, 1895 from Indochina are shown to have been misidentifications. This species is redescribed from the holotype from Sumatra, Indonesia. All previous records of Platyrhacus in Vietnam actually concern P. similis sp.n., a species apparently confined to south-central and central Vietnam. A different congener, P. borealis sp.n., lives in North Vietnam.
