Fletcher & Nye (1982) stated:-
Heterogynis ramburi Kirby, 1892, ibidem 1: 499 was proposed unnecessarily as an objective replacement name for H. paradoxa Rambur, 1837, which Kirby believed to be preoccupied in Heterogynis by `H. paradoxa, Hübn. (Bombyx P.) Eur. Schmett. ii.f.99 (1800?)', an incorrect authorship and an incorrect reference to Heterogynis paradoxa Rambur, Herrich-Schüffer, 1846, Syst. Bearbeitung Schmett. Eur. 2: 24; 1847, ibidem 2: pl.19, fig.99.
H. paradoxa is a form of Phalaena penella Hübner,  1796, Samml. eur. Schmett. 8: pl.67, fig.447.
Heterogynis was established in the Zygaenidae, Procridinae; it was placed in the Psychidae by Duponchel,  1844, Cat. méth. Lépid. Eur.: 66, but was transferred to the Heterogynidae, a seperate family established by Herrich-Schüffer, 1846, ibidem 2: 23. Neave, 1939, Nomencl. zool. 2: 638 lists the additional reference to Heterogynis Rambur, 1845, in Duponchel, ibidem: 66. Although Duponchel refers in a footnote on page 66 to `this new genus', a new genus is not being proposed; the generic concept is the same as that of Rambur's proposal in 1837 and includes the same nominal species.
Heterogynis, Rambur, 1837 and the Heterogynidae, Rambur, 1866, were proposed for placement on Official List of Generic and Family-Group Names in Zoology by Day, 1985; Bulletin of Zoological Nomenclature 42 (4) : 385.
