Leptocera sp.

Leptocera sp.
Alturas, Modoc County, California, USA
June 24, 2020
Size: 2 mm
At lights at night, 2 mm, collected. Eight marginal scutellar bristles (anterior pair quite small) and other features suggest one of the Leptocera spp?

Moved from Lesser Dung Flies.

Thanks -
John - any problem with my genus ID? The four pairs of scutellar bristles and other features should be pretty good, or am I missing something? Thanks!

Or Rachispoda
Leptocera and Rachispoda have been split.

This fly doesn't have the inwardly bent anterior dcs of Rachispoda, which I have have collected at least once I need to check again, but I thought even after the split that the eight scutellar bristles indicated Leptocera, that is what our Leptocera Info page says anyway..

I find the inward-pointing bristles difficult to see. Both genera have more than four scutellar bristles. In Europe they are supposed to have different numbers, six vs. eight. I have not checked that character for American species.

I -
have a Rachispoda specimen and I can see the inward-pointing bristles pretty easily (with the specimen in hand especially):

this one clearly lacks those.. unless you object, I will probably move this to genus and may try to key it to species using Buck and Marshall 2009.
