5-mm, Clitheroe UK, 7 April 2011. I only have this view. I have manipulated the layers of the stacked image to try to show off the leg chaetotaxy, but I can't decide on the genus: 2+4 dcs, a strong pd on t3 and only one posterior seta on t2. Sorry I couldn't catch it - no doubt another one will come along. EDIT: In your dreams, Robinson! Stephen R attached the following image:  [92.86Kb] Edited by Stephen R on 15-04-2011 22:19 |

I guess it must be Hebecnema, and that 'pd' must be an ad. |

I don't think it is Hebecnema. I'd prefer to see 2 original images, pd seems pd to me... Nikita Vikhrev - Zool Museum of Moscow University |

This one I think shows that there is no posterior seta in the basal part of t2. EDIT: though on looking again I'm not quite sure there isn't a second pd around the middle. This shot was a bit unsteady. Stephen R attached the following image:  [77.6Kb] Edited by Stephen R on 15-04-2011 21:05 |

I think we have to envisage Lophosceles cinereiventris as an option : arista, eyes not hairy, only one p seta on t2 inserted very low, calypters intensive yellow...

I did wonder about that, but it wasn't really in woodland. I've had another go at the last image, and I think there may be a second seta Stephen R attached the following image:  [90.73Kb] |

Bravo, Stephane! I had never seen this species neither in field, nor in collection, so I havn't any suggestion in additition to Stephane's. Nikita Vikhrev - Zool Museum of Moscow University |

It would be a great result! But I'd like to be sure my imaginary second seta really isn't there. Here is the adjacent layer in the stack. You could see almost anything in that noise!

I've looked through all the photos in the stack, and I'm fairly certain there really is only one posterior seta. So thank you Nikita and Stephane  Now to catch one... Edited by Stephen R on 15-04-2011 22:17 |
