Member Location: Vienna, Austria Posts: 1861 Joined: 23.06.15	I am not sure whether there are pv bristles present (first step in the Tschorsnig key), but assuming there are, I would be left with intermedia vs. auriceps. Fore tarsus widened and with a comb of spines (pro intermedia), but there are discal bristles on the abdomen (pro auriceps) Vienna, late September Edited by Carnifex on 01-10-2022 10:23 Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.

That placement is normal in Cylindromyia. In Tachinidae discal bristles are never or nearly never present on a segment without marginal bristles. I can not say how much of this is insect physiology and how much of this is human psychology ("we'll call this pair marginal even though they are not on the margin of the tergite").
