Acalypterate

Hi all

I have this acalypterate from a pan trap sample that for some reason I am really finding hard to get to family.

There is a strong costal break near the apex of R1 and an apparent slight weakness near the humeral cross vein, but I don't think this is a break. It has convergent post-verticals, the arista are pubescent and it has what appears to be a single long vibrissae. It also has spines on the basal part of the costa.

Thanks

Mike

Re: Acalypterate

The wing venation is typical for Limosininae (Sphaeroceridae).

Re: Acalypterate

Thanks Tony. I have gone back to the specimen and can see the hind metatarsus now.
