Explanation of Names
Etymology unknown ("dubious") (1).
Numbers
A Neotropical genus of at least 17 species, nearly all of which occur in Brazil (St. Laurent, Mielke, & Naumann, 2015). One species (imperialis) ranges widely in the eastern United States (and south to Argentina) but has severely declined in the Northeast in recent decades. E. oslari occurs in southern Arizona and much of Mexico.
Remarks
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.
