Atomariini - Tisactia

Atomariini - Tisactia
Somerset, Pulaski County, Kentucky, USA
June 28, 2012
Size: ~ 1 mm
Taken at UV light.

If I have this in the right family, this should be Tisactia, Ephistemus, or Curelius. Antennal grooves eliminate Curelius. I'm leaning towards Ephistemus as there doesn't seem to be a basal marginal bead on the elytra, as Tisactia would have. There is a species (Ephistemus perminutus Casey, 1924) whose description is a pretty good match.

Looking at it again, it seems to have basal marginal bead on the elytra. So possibly Tisactia, maybe teneral of the one I previously posted?
