It is defintely not Exoneura, but it is not clear whether it is a Lasioglossum or a Leioproctus species. In either case it would be a male. It think it is probably a Leioproctus species like L. platycephalus because it is hairier than I would expect for a Lasioglossum and the antennae are shorter than I would expect for a Lasioglossum (Parasphecodes) species.
