Hemming (1967) stated:-
When establishing this genus, Butler designated Pieris cynis Hewitson,  (Ill. exot. Butts 3 : , pl. , fig. 54) as the type-species of this genus. A year later (1871, Trans. ent. Soc. Lond. 1871 : 171) Butler stated that, when he had designated Pieris cynis as the type-species of Phrissura, he had misidentified under that name quite a different taxon, namely that represented by the nominal species Pieris illana Felder (C.) & Felder (R.). This is an exceptionally clear case of a genus based upon a misidentified type-species and, as such, it was submitted to the Commission for the correction of the type-species under the provisions of Article 70 (a). This application was published by the Commission, 1964, Bull. zool. Nom. 22 : 163. The correction so made of the type-species of Phrissura has the further incidental advantage that it saves the name Udaina Distant, 1885, which, having Pieris cynis Hewitson as type-species, would otherwise have fallen as a junior objective synonym of Phrissura.
The taxon represented by the nominal species Pieris illana Felder & Felder is currently treated subjectively on taxonomic grounds as being the same as that represented by the older-established nominal species Pieris aegis Felder (C.) & Felder (R.), 1861 (Wien. ent. Monats. 5 : 299).

Pieris illana Felder & Felder, 1862 was designated as the type-species of Phrissura Butler, 1870 using the plenary powers of the Commission. Pieris illana was placed on the Official List of Specific Names in Zoology and Phrissura was placed on the Generic Names in Zoology, (Opinion 824), The Bulletin of Zoological Nomenclature, 24 (4) : 220.
The higher classification used here follows Lamas (2008).
