 can anyone identify this possible tachinid. I think it might be one of the Gymnosoma (clavatum ?)Size approx 8mm. Found on rough vegetation at Portsdown Hill, Hampshire. Stuart Stuart Ball attached the following image:  [160.2Kb] |

Hi Stuart Pity we can see the frons. It's too big for clavatum and it really looks like (note the formulation) as a female of G. nudifrons. Which is never recorded in the UK, as fas as I know. DId you collect it. Or have pictures from front ? Theo |

Stuart told me that he didn't take a specimen BUT this photo reminds me of a female Gymnosoma that was sent to me recently (see images below). It was taken slightly out of the normal range for G. rotundatum and not on sand either. I have ruled out clavatum on the genitalia but I'd appreciate your comments Theo.

This is 100 % NOT nudifrons. As far as I can tell from the pic, it's a typical female rotundatum. Despite the atypical locality. Theo |

Ahh, no problem ... a slight range extension then and a different habitat to the norm, but nothing new then Would nudifrons have an entirely black, undusted frons? Edited by ChrisR on 20-07-2007 17:22 |

Yep, and slightly more smoky wings than in rotundatum. Both are suggested by Stuart's picture, however, I stress suggested. Theo |

No Theo, I did not take a specimen. I took only 3 pictures, none of which showed the frons. Stuart |

Pity. Maybe next time. It amazed me that you in the UK have not found G. nudifrons yet. You must have it, somewhere. So keep looking ! Theo |
