Eris C.L. Koch, 1846
Explanation of Names
Eris is Greek (Ερις, meaning "strife", or "discord") and was goddess embodying strife, discord, and rivalry (Wikipedia--Eris (mythology), Theoi Greek Mythology--Eris). The goddess Eris was associated closely with Enyo ("horror" or "warlike"), whose name was bestowed upon a sphinx moth.
4 species in bugguide's range: flava, floridana, militaris & rufa.(1)
Eris flava males typically shows a white band below the eyes that other Eris males do not.

See notes on distinguishing E. floridana from E. rufa here.

E. flava, E. floridana, E. militaris, E. rufa
See Also
Pelegrina - Eris has proportionately smaller palps, and a carapace that's more robust compared to Pelegrina. Also, I don't think any Eris have white scales under the ALE. Overall size is probably the easiest way to tell the difference. Once you've seen both genera you'll wonder how you ever got them mixed up.

I believe most (or all) male Pelegrina also have white scales beneath the ALE.
