Eacles Hübner, 1819
Explanation of Names
Etymology unknown ("dubious") (1).
Numbers lists 1 North American species, Eacles imperialis.

However, there is a second species E. oslari that is found in southern Arizona.
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.
