Before I submit this image to the gallery can I run it by an expert eye. I am confident it is D. unimaculata, but then again I have no reference to compare it with. So does it look plausible for D. unimaculata?

Not the best of images, but hopefully it would be of some use.

I do not know unimaculata either, but the impression I get of just this single picture is immigrans, but that is easy to discount if the fore femore do not have a row of peg-like setae. Otherwise, just this one image, without clear detail of the ovipositor (for example) is not really sufficient (for me) to give a proper ID.

Here is the fore femur. There are 7-8 tiny spines on the antero-ventral surface. Unfortunately D. unimaculata is not described in Baechli et al, but it does say that immigrans has ten spines here. Tough one. Does immigrans have any shading on the posterior cross vein? This one does.

This is D. immigrans, D. unimaculata does not have them.

Thanks Paul,
I'll go through the key and see where I went wrong.

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
