I think this is a wasp-like fly but maybe I am wrong and it is a fly-like wasp.

Odd antennae, they seem forked or doubled.

Length, 1.9 mm. Attracted to mercury vapor light, West Virginia, USA.

ID help appreciated.

What a creature!
Nevertheless I think it is Diptera, Brachycera.
My reason is - Insecta have no forked legs or antennae, as Crustacea.
Thus, the only possible explanaition I can find is, that it is enlarged 3-d antennal segment and long, hairy dorsal arista.

Ceratopoginidae, a male. The longer part of the antennae are formed by the true antennal segments. The shorter part are hairs on the basal segments that come together to form a kind of brush.
