Prays was placed in the Yponomeutidae by Nye and Fletcher, 1991 Generic Names Moths World, 6 : 249.
Prays Hübner, 1825, was designated as the type-genus for the new subfamily Praydinae, Moriuti, 1977, Fauna Japonica, p.32.
Nye & Fletcher (1991) stated:-
When Walsingham designated as type-species Phalaena curtisella Donovan, 1793, Nat. Hist. Br. Insects 2: 77, pl.65 fig.4, a nominal species not originally included in Prays, he also placed caenobitella (but cited as * Coenobitella, an incorrect subsequent spelling) a nominal species that was originally included in Prays, as a junior subjective synonym of curtisella. Under the Code (Edn 3), Article 69(a)(v), this designation constitutes the fixation of the originally included nominal species as the type-speies. The type-species was included in Prays as * Coenobitella, an incorrect subsequent spelling. Unavailable designation of type-species: Phalaena curtisella Donovan, 1793, a nominal species not originally included in Prays and not linked in synonymy with one of the originally included nominal species when cited as type-species of * Pratys, an incorrect subsequent spelling of Prays, by Desmarest, 1857, in Chenu, Encycl. Hist. nat. (Papillons nocturnes): 303.
