I think this is a phaonia but I'm better with the ones with yellow legs  Generally quite dark, 11mm long from woodland ride. peterbolson attached the following image:  [60.44Kb] |

Can I resurrect this one as it's still puzzling me. Perhaps it's not even a phaonia ? Peter |

I didn't see this thread, sorry. It do is Phaonia : from what I can see : no strong prst acr., pra longer than post nt, mid tibia with pv, arista long plumose : can you check for Phaonia incana ?

No need to apologise. You do a wonderful job on this site Stephane but you can't be expected to answer everything. I can confirm all the features you mention, but I can't see 2 rows of seta on the post. surface mid tibia or posterior seta on the fore tibia. Notopleuron is haired, meron & katepimeron bare. Sorry about the quality of the photos - it is a very black specimen. I can try some more if you want. Regards Peter |

I see a post seta on your first picture (rather long). For the 2 rows on mid tibia, it is less obvious, but I guess some setae oriented in both directions (ventral and dorsal). Maybe a picture of t2 could make us sure.

This is the best I could manage - wish I had a camera attachment for my microscope . Ventral view of right T2

It seems to have at least a pv, at least a much more ventral than the others.

I agree ; so can we come to any conclusion ? Incidentally I use Gregor et al and the key there has no mention of a PV on the mid tibia for P.incana. Peter |

Well, pv on mid tibia are the second row of posterior setae ; pd make the first row. So the key mention this, indirectly...

I see what you mean ( I think ). The other thing is that there is no pd seta on the basal third of the hind tibia. I've started from scratch & run it through the key & it does come out as P.incana. As you know I'm a beginner at this but I've learnt alot from this one. Thanks for your patience Stephane. Regards Peter |
