Most likely Ornothomyia chloropus. ID based on the pattern of microtrichia on the wing. However, O. fringillina can have the same pattern. To be certain, check whether there is a dark marking on the ventral part of the gena. If so, then chloropus is confirmed, otherwise it is fringillina.

Thanks Paul. I will look for a dark marking on the ventral part of the gena.

I think we still need to exclude (or not) biloba.

So, Dick, could we get a dorsal shot of the head as well ?

Thanks

OK, so no biloba.

Acoording to the wing mictrotrichia, it is chloropus (as Paul pointed out).
According to the head underside, it is fringillina.

I must say, I have doubted the species status of chloropus for a long time, this is yet another example.

According to the latest publication this should then be fringillina, but form you own opinion after reading this: http://www.sencke...19-125.pdf.

Yes, thanks for the paper.
I feel the urge to state that I totally disagree, though.
Statistically you cannot (never !) estimate the variability based on two records only.
If I understand them correctly, that is what they claim to have done.
Simply no-go.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
