Heliastus benjamini Caudell, 1905. Type locality: Huachuca Mountains, Arizona
Explanation of Names
The proper name for this species should be Heliastus nebulosus, since that species name is older than "benjamini". However, that combination of genus and species name has yet to be published, and BugGuide is not a proper place to publish new combinations.
