Hemming (1967) stated:-
Oken placed all the Hesperiids in the genus Erynnis Schrank, 1801 ; under that name he cited (: 757) three names as synonyms, one of these being Thymale, no authors' names being cited for any of these names. He divided the genus (: 758) into two groups, to the first of which he assigned the name Thymale. Although it is impossible to be certain, it is most likely that the name Thymale Oken is an Incorrect Subsequent Spelling of Thymele Fabricius, 1807. In any case by the type-selection specified above the name Thymale Oken is a junior objective synonym of Thymele Fabricius, which in its turn is itself a junior objective synonym of Erynnis Schrank, 1801.
Even if Thymale Oken had been otherwise available it would nevertheless have been invalid owing to the fact that in 1956 (Opin. int. Comm. zool. Nom. 14 : 1-42) the Commission by its Opinion 417 rejected Oken's Lehrbuch for nomenclatorial purposes.
Cowan (1970: 31) stated:-
"THYMALE" Oken, 1815, LehrB. Naturg. 3 (Zool.) (1) : 757, 758. Not available.
Hemming showed (1967 : 442) that this name appeared, as a synonym of Erynnis Schrank, 1801, in an officially rejected work. He suggested that it was a misspelling of Thymele Fabricius, 1807. It was, indeed, probably a widespread misspelling, and a further 1815 example is listed in the final chapter below.
The higher classification used here follows Lamas (2008).
