Unknown Scathophaga from Mull of Kintyre
I have been unable to identify a male swept from "beach edge" by Andrew Halstead on 17/06/2005 at Wesport Dunes, Macrihinish (NR655261) on the west coast of the Mull of Kintyre. Whilst it seems to belongs to the group of sea coast species around S. litorea / S. calida (with a bare arista and hairy pteropleuron) of which there are many more around the coasts of Greenland, Canada and the Russian arctic, it does not appear to key out in Hackman (1956)
