The parafacial does look dark and hairy but I can't see the lemon-yellow halteres that I would expect to see on P.barbifrons. It would still be my best guess but maybe Theo can comment on it  |

Look at the second pic, the parafacialia are all hairy, so it definitely is barbifrons. The yellow halters are covered by the calyptrae. Theo |

Thanks On this "bad" photo, I think you can see the yellow halters. Christine Devillers attached the following image:  [98.16Kb] Edited by Christine Devillers on 28-08-2008 21:36 |

I'd go for that too, easier to see than the parafrontal bristles - even if I copy Pic 2 and then work on it with Paintshop all I can see is something that are probably bristles. Matt |

Right. The point is, however, that in pusilla there is nothing, except 1 row of bristles. So 'anything more' implies 'not pusilla' By the way, the last pic shows the hairs on parafacialia better. Theo |
