I ruled out all the genera from eastern North America.

Aprhia, Clausicellla, and Ginglymia are darker.
Crocinosoma has big antennae.
Drepanoglossa has longer proboscis.
Genea has more bristles on veins R1 or R4+5.
Superficially it looks like Leskia. The two regional species of Leskia differ. According to the key to genera, Leskia should have only one ad on mid tibia.
The eastern species of Solieria has discals and all the species are at least a bit darker.
