Unavailable designation of type-species: P. goedartella Linnaeus was designated by Boisduval, 1836, Hist. nat. Insectes (Spec. gén. Lépid.) 1: 150. In the Introduction to the volume, pages 1-154, Boisduval reviewed earlier classifications of Lepidoptera and designated up to three different type-species for each generic name. In his "Expose de notre Méthode", pages 155-690, no type-species designation was made for any of the genera he himself used. Under the Code (Edn 3), Article 69(a)(iv), the type-species designation of an author is eligible for consideration if he states that it is the type "... and if it is clear that the author accepts it as the type-species". Boisduval's type-designations, although clearly stated, do not fulfil the last requirement and so are unavailable. Even though Boisduval's 1836 work was well known to lepidopterists, the type-designations have not been accepted by Hemming or by other authors.
Argyrosetia was again proposed by Stephens, 1829 [July], Syst. Cat. Br. Insects (2): 205, and again by Stephens, 1834, Illust. Br. Ent. (Haustellata) 4: 251. Argyrosetia is a junior objective synonym of Argyresthia Hübner, .
