Schizaphis viridirubra (Gillette and Palmer 1932) = Schizaphis (Paraschizaphis) nigra (Baker 1918)

Eastop (1961) pointed out the similarity between nigra and viridirubra after examining type material, and the fact that both share the unusual character of consistent presence of large marginal tubercles on abdominal segment 6 suggests that they are conspecific. S. nigra has previously been placed in subgenus Paraschizaphis, due partly to confusion with short­haired specimens of S. caricis .
