Hemming (1967) stated:-
Fabricius established this genus with a short diagnosis but without citing any established nominal species as belonging to it. He did however, enter under Helias the manuscript specific name phalaenoides. Thereafter, this name was unnoticed until in 1862 (Wien. ent. Monats. 6 : 186-187) it was revived by Cajetan & Rudolf Felder who expressed the view that it ought to be brought into use and who thereupon placed in it a considerable number of nominal species, one of which was Urbanus phalaenoides Hübner,  ; this species was selected as type-species by Butler in 1870. Thus, ultimately, the species which Fabricius no doubt had in mind, when on establishing the genus Helias he cited the manuscript specific name phalaenoides became the type-species of Helias.
The higher classification used here follows Lamas (2008).
