Moved from Tanaostigmatidae.

Moved from Encyrtids.

Moved from Chalcid Wasps.

I can see why ...
... you thought this might be an Elasmus, but the bulging mesopleuron suggests this is an encyrtid, which, like the Eulophidae, has a few genera with branched antenna in the male. The elongate marginal vein makes me think this is either Charitopus or Neocharitopus.

Thank you Bob!
I appreciate your help and explanation.

Well, looks like I made an error
This is likely NOT an encyrtid, but rather something from the family Tanaostigmatidae.

After a little more investigation ...
... this appears to be a member of the genus Tanaostigmodes. Unfortunately, the best key for this genus is based on females, and this is a male.

I wasn't familiar with this family at all
which is distributed worldwide, but for some reason, the few BugGuide entries have been posted by Charles W. Melton from Arizona.
