Costal cell appears to only have 50% with hairs but there do appear to be strong bristles on the gena, so I am a bit confused. But certainly it looks like Linnaemya (hairy eyes, parafacial without many bristles, facial ridges without many bristles, protruding mouth edge, yellow basicosta etc etc) Nice photos, by the way

Member Location: Galicia (Spain) Posts: 170 Joined: 29.05.06	Thank you for your help, Chris. I was a bit confused about Linnaemya, in the Central Europe Tachinidae keys of Tschorsnig and Herting figures Sides of the thorax with yellow hairs for this genus. Probably the photos do not show these hairs. In the Portugal+Spain checklist of Carles-Tolr?(2002) Cat?logo de los Diptera de Espa?a, Portugal y Andorra, the following Linnaemya are included: L. comta, L. fissiglobula, L. helvetica, L. impudica, L. lithosiophaga, L. media, L. picta, L. soror, L. tessellans, L. vulpina.

The bristles are black, but there is also quite a profusion of finer pale hairs in the fourth image. It may be a trick of the light though - in the second image the hairs do look black. What does it look like in real life under magnification? Susan

Administrator Location: Reading, England Posts: 7699 Joined: 12.07.04	I must admit I can't see yellow hairs clearly, and like Susan said, it might be a trick of the light. The Central European key won't be 100% guaranteed to help because it doesn't work so well south of the Pyrennes or Alps. Remember, on the subject of yellow hairs it might be that feature only works for species in the Central/Northern European region and there could be Linnaemya spp. outside that area that don't have yellow hairs. But you'd have to ask Peter Tschorsnig about that - he does do some work in the south and he'd have a clearer idea about the fauna in your area. One thing for sure, it certainly isn't a Clairvillia spp. (have a look here: http://www.dipter...oto_id=249). So, I'd say you should use the Central European key as best you can and see which Linnaemya spp. it comes out to... but don't be 100% confident on the identification until you can find literature that specifically covers your part of Europe Edited by ChrisR on 17-01-2007 14:15
