Hi Tor,

Thanks for posting the extra photos. First of all, I hope Theo doesn't mind if I clear up that it is tibialis which has hairs ventrally on R1 and apicalis is bare ventrally, so Theo means tibialis rather than apicalis on seeing dorsal and ventral R1 hairs.

I still think I see hairs dorsally but I'm not sure ventrally; its easier to decide if the photo is taken at an angle rather than directly above. I've circled on your photos where the hairs might be. I really think I can see about 4 bristles on the dorsal R1.

You are quite right that Haraldseide (Checklist of Norwegian Tachinidae 2012) lists just hertingi and setinervis for Norway and that both these species have R1 bare dorsally. Another difference between this pair and tibialis / apicalis is that the hairs on R4+5 should not extend much beyond m-cu for tibialis / apicalis but they do in this specimen, so I am a bit puzzled. I will check my collection for variation but I just have apicalis (several) and tibialis (one).

regards,
Steve
