Hemming (1967) stated:-
Godman designated Ancyloxypha simplex Felder (R.), 1869 (Verh. zool.-bot. Ges. Wien 19 : 476) as the type-species of this genus. There is however clear evidence that he misidentified the nominal species Ancyloxypha simplex Felder and that the species to which he incorrectly supposed that name to apply was, in fact, Apaustus prittwitzi Plötz. First, Godman gave four figures (male - upperside ; male underside.; venation, male genitalia) (figs 30-33 on pl. 92) of what he then identified as Ancyloxypha simplex; all of these are referable to Apaustus prittwitwi. Second, Godman gave (: 471) a description of his "simplex Felder"; this applies to Apaustus prittwitzi but not to the true Ancyloxypha simplex of Felder. Third, he gave (: 470) a diagnosis of the genus Adopaeoides which agrees with the characters shown by Apaustus prittwitwi but not with those of Ancyloxypha simplex.
In the most recent treatment of this group (1955, Cat. Amer. Hesp. Brit. Mus. 4 : 309) Evans, after summarising the evidence set out above, treated Apaustus prittwitzi as the types-species of this genus, at the same time identifying the true Ancyloxypha simplex Felder with the older-established nominal species Ancytoxypha aurantiaca Hewitson, 1868 (Descr. One Hundred new Spec. Hesp. (2) : 45). With this latter also there is identified the later-established nominal species Heteropterus procris Edwards, 1871 (Trans. amer. ent. Soc. 3 : 215), the type-species of the genus Copaeodes Speyer, 1877 (in Edwards, Trans. amer. ent. Soc. 6 : 49, 64). Thus on the basis of the subjective synonymy set out above the generic name Adopaeoides Godman would disappear as a junior subjective synonym of Copaeodes Speyer, if the true Ancyloxypha simplex Felder (the nominal species designated by Godman) and not the species Apaustus prittwitwi Plötz (the species misidentified with Ancyloxypha simplex by Godman, were accepted as type-species of Adopaeoides. In that event the species Apaustus prittwitzi would lose the name Adopaeoides currently applied to it and would in futurehave to be known by the name Neadopaea Hayward, 1941, a name introduced against this contingency which however has not recieved a favourable reception.
An application has been made to the Commission to use its Plenary Powers to secure that in harmony with Article 70(a) of the Code the nominal species to be accepted as the type-species of Adopaeoides Godman shall be Apaustus prittwitwi Plötz, the species intended by Godman when he erroneously used the name Ancyloxypha simplex Felder. In the interests of nomenclatorial stability the name Adopaeoides is here provisionally treated, in anticipation of a ruling by the Commission, as though a ruling in the foregoing sense had already been given.
Cowan (1968) made the following comment for this and other genera:-
Opinions published in September and December 1967 in Bull. zool. Nomencl. 24, parts (4) and (5) CONFIRMED the forecasts given in the List [Hemming, 1967] for the following genera;
Adopaeoides Godman; Op. 825
Arisbe Hübner; Op. 823
Artines Godman; Op. 826
Gegenes Hübner; Op. 827
Halpe Moore; Op. 828
Iaspis Kaye; Op. 821
Napaea Hübner; Op. 820
Papias Godman; Op. 829
Phanes Godman; Op. 830
Phrissura Butler; Op. 824
Telicota Moore; Op. 831
Ypthima Hübner; Op. 819
Zenis Godman; Op. 832
Apaustus prittwitzi Plotz, 1884 was designated as the type-species for Adopaeoides Goodman , using the plenary powers of the Commission. Apaustus prittwitzi was placed on the Official List of Specific Names in Zoology and Adopaeoides was placed on the Generic Names in Zoology, (Opinion 825), The Bulletin of Zoological Nomenclature, 24 (4) : 222.
