Hemming (1967) stated:-

Like all other new species-names published in the Verzeichniss, the name Ithomia drymo is based solely upon bibliographical references. In this case the reference cited by Hübner was : "Diaphane Cram. 315 D.E.", i.e. to plate 375 (figs D & E) published in 1780 by Stoll in Part 27 of his continuation (volume 4) of Cramer's Uitl. Kapellen. In the text (: 53) Stoll stated that these figures represented the upperside and underside of the female of the species of which the male had been described and figured under the same name - Papilio diaphana - by Cramer in 1779 (Uitl. Kapellen 3 (20) : 66, pl. 231, fig. C). The name Papilio diaphana Cramer ranks for priority as from 1779. There are two older nominal species bearing the name Papilio diaphanus, the first of these being Papilio diaphanus Drury, [1773] (Ill. nat. Hist. 2 : index et 13). Since the words "diaphana" and "diaphanas" are no more than gender variants of a single word, it follows that the name Papilio diaphana Cramer is a homonym of the name Papilio diaphanus Drury and being the later published of these two names is invalid under the Law of Homonymy. The oldest available name for the type-species of the present genus is the replacement name Ithomia drymo Hübner, 1816.
