The generic name Riazocoris Ahmad & Afzal first appeared in the paper by Ahmad et al. (1977) describing the internal organs of Riazocoris niger . In that paper neither the type species of Riazocoris has been designated ( ICZN 1999 : Art. 13.3) nor it became available as a combined description of new genus and species because none of the taxa was marked as new ( ICZN 1999 : Art. 13.4). The name Riazocoris was made available by Ahmad & Afzal (1979) .
