Fletcher & Nye (1984) stated:-
Phalaena sulphuralis Stoll, 1781, is a junior primary homonym of Phalaena sulphuralis Linnaeus, 1767, Syst. Nat. (Edn 12) 1 (2): 881 - Lepid. , Noctuidae. There is no objective replacement name but P. sulphuralis Stoll was placed by Hampson, 1899 Proc. zool. Soc. Lond. 1898: 610, as a senior subjective synonym of Phalaena lepidaria Stoll, 1781, in Cramer ibidem 4: 161, pl. 371, fig. K; the latter is thus available for use as a subjective replacement name. Stoll, 1782 ibidem 4: 250, included Phalaena lepidaria in the index to the volume as Phalaena * Lepidalis, an incorrect subsequent spelling.
The Stoll names are dated from the wrappers of the parts, not from the title-page of the volume which is dated 1782.
Symphysa was established in the Pyralidae Pyraustinae; it was transferred to the Pyralidae Evergestinae by Munroe,  1973, in Moths Am. N. of Mexico 13 (1C): 254, where it was cited as `Symphysa Hübner', an incorrect authorship.
