Nye & Fletcher (1991) included EPIGRAPHIA in the subfamily OECOPHORIDAE: DEPRESSARIINAE, treated by Hodges, in Kristensen (1999) as a subfamily of ELACHISTIDAE.
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 the genera. Unavailable designation of type-species: P. avellanella 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 classifiucations 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-pecies 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.
Epigraphia was again proposed by Stephens, 1829 [July], Syst. Cat. Br. Insects (2): 202.
Epigraphia Stephens, 1829 [June] was treated in the Oecophoridae, Depressariinae by Nye & Fletcher, 1991, Generic Names Moths World, 6 : 113. Epigraphia has subsequently been designated as the type-genus for the new tribe Epigraphiini (Depressariinae - Elachistidae), by Leraut, 1992, Entomologica Gallica 3 (3) : 134.
