Excellent work, and I still can't make the species. I could do with a shot of the thorax obliquely from behind (so 45 degree angle, not 90 degree as above). Or, alternatively, a lateral shot of the male genitalia. It might be clavatum. Theo |

Thanks Theo, sorry I have been awkward and trying to photograph it I have destroyed the pinned fly. I hope to capture it again. Ciao Pietro |

Well, that is not possible since those Gymnosoma are all so similar and they often fly intermixed. I'm 90 % confident that this is a male clavatum. So the last 10 % remain uncertain. Theo |

Thanks Theo, it's not hard to meet it again, in Sardinia Cerretti signals 3 Gymnosoma: the rungsi that I easily recognize for the absence of vibrissa and bristles perivibrissal, the clavatum the rotundatum. Ciao Pietro |
