Synonymized with Rhopalopsyche nycteris as a subspecies by Seitz, 1929, in Seitz (ed.), Die Gross-Schmett. Erde 10: 562. Reinstated (inadvertently) as a species by d'Abrera, 1987, Sphingidae Mundi: 167, 168, who nevertheless considered that bifasciata "is probably only a geographical race of nycteris Kollar". Transferred to Macroglossum by Kitching & Spitzer, 1995, Tinea 14: 815.
