Hemming (1967) stated:-
At a time when it was erroneously supposed that the name Euptychia was first published by Hübner in the Verzeichniss ((4) : 54), which was then treated as having been published in 1816, whereas in fact the greater part of the butterfly section, including signature 4 here in question, is now considered not to have been published until 1819, Butler selected (1868, Ent. mon. Mag. 4 : 194) Papilio herse Cramer,  (Uitl. Kapellen 1 (1) : 15, pl. 10, figs C,.D) as type-species and Euptychia came to be accepted as the name for the large Neotropical genus of which the above species is a member. When it came to be realized that the name Euptychia was first published in the Zuträge in 1818 (that is, one year before the relevant portion of the Verzeichiss), it became impossible to maintain Papilio herse as the type-species, as it was not one of the two species placed in Euptychia in the Zuträge. Fortunately, one of those species, Euptychia mollina Hübner, belonged to the same general group, and its selection as type-species by myself in 1937 gave a valid basis for the current interpretation of this genus.

EUPTYCHIA, line 7; "1819. Butler should read; 1819, Butler.
EUPTYCHIA was included within the subfamily NYMPHALIDAE: SATYRINAE by Ackery et al., in Kristensen (1999).
The higher classification used here follows Lamas (2008).
