I am not 100% sure, but it seems to be an Heterostylodes sp. (Anthomyiidae) Joke |

The shape of the ovipositior in the second image suggests Phorbia, but I realise the pv apical seta on the hind tibia is not visible in these images.

I've never seen Heteostylodes, but the key says it should have the mouth edge protruding beyond the parafrontal angle (rather like Egle). Phorbia seems a better fit here on that count too. |

And if it is Phorbia, from the features I can see (crossed interfrontals, orbital and frontal bristles not in a straight line, t2 with 1av+1ad+2pd, dorsal margin of cerci not straight in distal half, genal setae not uniserial), Ph. fumigata would seem to fit best. |

Assuming there are no similar species in Italy that lack from your key.

Thanks a lot for your attention, here the list from the Italian fauna about Phorbia genus: Phorbia Robineau-Desvoidy, 1830 Phorbia curvicauda (Zetterstedt, 1845) (N) (*) Phorbia fumigata (Meigen, 1826) (S) Phorbia italica Ackland & Michelsen, 1987 (N) Phorbia juncorum Ringdahl, 1959 (N) I add another image, with the Phorbia upside-down  , I hope it can help in some way.Best regards Claudio Claude54 attached the following image:  [172.71Kb] Edited by Claude54 on 08-11-2011 22:57 |
