Hemming (1967) stated:-
Under Article 69(a) (ii) (3) from among the first nominal species to be placed in the genus (Duponchel, 1835, in Godart, Hist. nat. Lépid. Fr. Suppl. 1 (Diurnes) : 413.
The name Heteropterus was first published in 1806, in which year it appeared both in the French text of Duméril's book and also in Froriep's German-language edition issued under the title Analytische Zoologie. The precise dates of publication of these two editions is not known, but this is not a matter of practical importance, because the texts of these volumes are identical ; in each the name Heteropterus appeared on page 271.
No nominal species was placed by Duméril in this genus in 1806. When Duméril next dealt with the name (1823, Consid. gén. Class. Ins. : 222, pl. 41, figs 6-9. he once more cited no nominal species as belonging to it ; in the explanation to the plate referred to above he designated the species there figured by the French vernacular name "Heteroptere miroir". The species concerned (which is still popularly known by this vernacular name among French collectors) is now, and for long has been known as Heteropterus morpheus (Pallas) (originally described as Papilio morpheus Pallas, 1771, Reise durch verschied. Provinz. Russisch. Reichs 1 : 471).
The first author to cite duly established nominal species as belonging to the genus Heteropterus was Duponchel who in 1823 (loc. cit., Suppl. 1 : 431 cited three such species. The first of these was Papilio aracinthus Fabricius, 1777 the taxon represented by which is - and for long has been - treated as the same as that represented by the nominal species Papilio morpheus Pallas discussed above. Kirby in 1870 (J. linn. Soc. Lond., Zool. 10 : 500) selected as the type-species the nominal species Papilio speculum Rottemburg, 1775 (Der Naturforscher 6 : 31), another nominal species considered to represent the same taxon as that represented by the nominal species Papilio morpheus Pallas. The selection made by Kirby is invalid because Papilio speculum was not one of the nominal species placed in the genus Heteropterus by Duponchel in 1835, as for the same reason are all selections by later authors of Papilio morpheus Pallas. The genus remained without a validly selected type-species until Papilio aracinthus Fabricius, 1777, was so selected by myself in (1934 : 167).
It will be seen from the foregoing particulars that Papilio aracinthus Fabricius, the name of the type-species of this genus, is currently treated as a junior subjective synonym of the name Papilio morpheus Pallas, 1771.
The higher classification used here follows Lamas (2008).
