Fly found on kelp/seaweed - Coelopa frigida

Fly found on kelp/seaweed - Coelopa frigida
Green's Point, Charlotte County, New Brunswick, Canada
January 15, 2014
Size: 6 mm
I believe this could be 'Species Coelopa frigida'. Was found on seaweed/kelp wrack. There were many small 2mm flies and far fewer of these particular ones. Reading Marshall's 'Insects Their Natural History and Diversity' pp 420-421, it directs to an image on page 507 - #4 .. which says there is only one species of Coelopidae in the NorthEast which is Coelopa frigida. That is how I deduce this species. After a very cold spell of weeks of -20 degrees C, a few days of +5 C degree days happened and I found these on the edge of the ocean (Bay of Fundy) in kelp/seaweed deposits at the high tide line (wrack line).

Thanks ....
... for moving to species. I figured it had to be this.

Could be Coelopa frigida
The other shoreline species with complete Sc and no subcostal break is Orygma luctuosum, which seems to be less bristly.
