Hemming (1967) stated:-
Geyer, like his predecessor Hübner and many other early authors, gave no indication as to whether the generic names that he used were new names or, in the case of similar names emendations of older names. In the present instance, the name used by Geyer - Eumaea - might very well have been from Geyer's point of view an emendation of the earlier name Eumaeus Hübner, , having regard especially to the fact that even today the taxon represented by the nominal species Eumaea debora Geyer is subjectively regarded on taxonomic grounds as being congeneric with Rusticus minijas Hübner, , [see Cowan's note below] the type-species of the genus Eumaeus Hübner, . However, it cannot be claimed that Geyer provided any clear evidence that his Eumaea was intended to be an emendation and accordingly under Article 32 (a) (ii) of the Code it cannot be treated as an emendation ; nor does Geyer's volume contain anything which would support the view that the spelling which he used was an inadvertent Incorrect Subsequent Spelling. It is necessary therefore to conclude that under the Code Eumaea Geyer should be treated as having been a new name deliberately introduced by that author. Luckily, from the practical standpoint the matter is of no importance, since, for the reasons explained above, the name Eumaea would not be required for taxonomic purposes, being at the best no more than a junior subjective synonym of Eumaeus Hübner, .
Cowan (1970: 46) stated:-
EUMAEA, EUMAEUS, EUMENIA: Rusticus minijas is often misspelt "minyas". The "copperplate script" on Hübner's plate [971, as also on the 1904 Wytsman reprint, clearly shows the two dots over the ij, without which they would read as "y".
The higher classification used here follows Lamas (2008).
