The origin of the genus name
Eacles is a real puzzle. Perhaps it is a misspelling or a typographical error. Some possible intended words (speculative) are
Eocles/Eokles and
Eakles/Aekles--the latter are, perhaps, surnames. Perhaps related to
Eteocles?? There is, unfortunately, no entry in the
Oxford English Dictionary for this name.
The original publication (from
Lepidoptera and other life forms) is
Eacles Hübner, [1819]; Verz. bek. Schmett. (10): 153.
