Nye (1975) stated:-
N. serena is a junior subjective synonym of Phalaena bi[c]olorata Hufnagel, 1766, Berlin. Mag. 3 (4): 410. The original spelling by Hufnagel was biolorata, but ever since, for over 200 years, it has been known in all works and nomenclators (including that of Sherborn) as bicolorata. An application under the Code, Article 79, should be submitted to the Commission requesting that P. bicolorata be made nomenclaturally available from 1766.
Aethria Hübner, , is a junior homonym of Aethria Hübner,  1816, Verz. bekannter Schmett. ; 120, -Lepid., Ctenuchidae. There is no objective replacement name but N. serena is congeneric with Phalaena brassicae Linnaeus, 1758, the type-species of Mamestra Ochsenheimer, 1816. The latter is therefore available for use as a subjective replacement name.
See: MAMESTRA Ochsenheimer, 1816.
Poole (1989) included DIATARAXIA Hübner, ; AETHRIA Hübner, ; and PEUCEPHILA Hampson, 1909 as junior synonyms of LACANOBIA Billberg, 1820.
