Can't tell species
Two species are known from North America:

Eugnoriste brevirostris has mouthparts either "slightly longer than the head" (Johannsen, 1912) or half as long as the head (Mohrig, 2012).

Eugnoriste occidentalis has mouthparts longer than head and thorax combined, and is a western species.

Thanks for the comment John. I hadn't seen Mohrig etal (2013) yet.

I do not think it is E. brevirostris because of the very elongate mouthparts and wing venation, which is illustrated for E. brevirostris only in Mohrig (Fig. 30). In the specimen at hand, the costal vein extends noticeably further past the apex of R5.

The specimen I have, and I've not seen additional examples yet, is perhaps closer to E. occidentalis if you rely solely on the length of the mouthparts. The original drawing by Coquillett is republished (fig 1) in Mohrig etal (2013) but is somewhat crude. This would however put it far out of its known range.
