Apterona helix (Siebold, 1850), referred to as Apterona crenulella (Bruand, 1853) by some authors, has been the name applied to North American specimens of this species. This is treated as a parthenogenetic form of Apterona helicoidella (Vallot, 1827) by the World Catalogue of Insects, Vol. 10: Psychidae (Lepidoptera) (1) and Pohl et al. 2016 (2).
