@ Theo and Steve Well it seems to be a difficult identification this time. 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 |

Hi Tor, thanks again for the extra photos, I see now that the earlier photo which looks like a bifid antenna is due to the coincidental position and shadow of the arista! 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 |

So, it is female and the antenna is not bifid. At least that makes sense ! Theo |

Hi Yes, at least it makes sense I put on my last picture here, and now I will say that this fly is a female P.hertingi Keyed after Anderson: "Tarsomere 2 of fore legs in female not enlarged, equal in widt to tarsomere 1" Thanks to both of you, Theo and Steve I've learned a lot Tor S attached the following image: [72.6Kb] Edited by Tor S on 24-10-2014 10:11 best regards Tor S |

The second aristal segment is also strongly elongated, in accordance with P. hertingi. Seems we got to the end of this road (J.J. Cale). Theo |
