Nye & Fletcher (1991) stated:-
The citation by Duponchel is acceptable as a type-species designation as it is contained in the continuation of a layout in which Duponchel stated, in the same work 7 (2): 102, that the species so cited were the types of genera.
Unavailable designation of type-species: P. geoffrella was designated (as geoffroyella) by Boisduval, 1836, Hist. nat. Insectes (Spec. gén. Lépid.) 1: 149. In the Introduction to the volume, pages 1-154, Boisduval reviewed earlier classifications of Lepidoptera and designated as many as three different type-species for each generic name. In his "Exposé 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". Boisdival's type designation, although clearly stated, do not fufill the last requirement and so are unavailable. Even though Boisduval's 1836 work was well known to lepidopterists, the type-designation contained in a have not been accepted by Hemming or by other authors.
Invalid designations of type-species: Pyralis tunbergiana Fabricius, 1781, was designated (as thunbergana) by Westwood, 1840, Introd. mod. Classif. Insects 2 (Synopsis Genera Br. Insects): 110, and Tinea lobella [Denis & Schiffermüller], 1775, was designated by Fletcher, 1929, Mem. Dep. Agric. India (Ent.) 11: 77. Each has been accepted as the type-species by some authors.
Enicostoma was again proposed by Stephens, 1829 [July], Syst. Cat. Br. Insects (2): 199, and by Stephens, 1834, Illust. Br. Ent. (Haustellata) 4: 226.
