The Netherlands, Tilburg, 4-10.VI.2012. Can anyone narrow it down a bit? Perhaps Iain? Jan Willem attached the following image:  [167.96Kb] Jan Willem van Zuijlen |

Hi Jan Willem I hope you are well. The specimen is fortunately one of the easier Lonchaeids to identify! - with short antennal flagellomere and long dorsal setulae half way along the apical segment of the aculeus it is Protearomyia nigra best wishes ......... Iain Iain MacGowan |

Hi Iain, I'm fine thanks. Hope you are well also! Thanks a lot for the identification of the specimen. Species level is better than I expected  .

Iain, with the longer dorsal apical setulae, is greciana not more likely? The British key does not show these dorsal apical setulae. I had a similar specimen from one of our museum windows today and greciana is where I ended up initially.

Hi Paul well spotted - I think there is actually an error in the key illustration as P. nigra does have a pair of long dorsal setae on the apical segmnet of the aculeus. One further complication is that I have found there to be a futher 3 undescribed species of Palearctic Protearomyia, one of which appears relatively common in western Europe - so at present although I can distinguish the males I am rather cautious about naming females! best wishes .........

I would not mind receiving some info on these other species and what might tell me the difference between females of greciana and nigra. I collected two males this last weekend in Germany and it could mean additional material to study for you.
