I have got an aswer from mr Haraldseide, and he is of the opinion that this is a female P. hertingi. I add two more pictures this time, and one of them, the lateral, shows the front leg and tarsus. (Andersen point to this) Theo wrote: "Funny, in one it is bifid, in the other one it is not Tor, is this really one and the same ??" -answer; Yes. I only have this Peribaea Steve wrote: "So I still think this is tibialis/ apicalis and therefore a new record for Norway maybe." Well, that be fun an amateur find the new specie for the country. I must say thank you very much for the interest and work you show on this fly. Tor S attached the following image: [141.89Kb] best regards Tor S

Photographs are a lot trickier to decipher than holding a specimen under a stereo microscope which is why we were asking for different angles. It was certainly our honest opinion that there were out of focus hairs on the apical r1 in the photos you posted, though the close-up of the arista in your most recent photo is certainly consistent with hertingi or setinervis. I'm not sure I understand your comment regarding the possibility of "amateurs" finding species additional to a published country list - it happens all the time, a local friend here in the UK has added several tachinids to the UK list, I have added to the Italian fauna and many others who post on Diptera.info have extended the known ranges of European species... regards, Steve Edited by sd on 23-10-2014 21:37
