I have tried to identify a Meromyza species using Fauna Ent. Scand. In the key I come to a step where I need to look at the postgonites.
My question is: Is it the black things I have marked with red that are the postgonites?

Genitalia seem closest to rohdendorfi (the shape of the postgonites as you indicate in the first image), but the hind femro are not nearly as swollen enough as mentioned in the key. My non-expert opinion...

Well, if you can confirm that the tips of the palpi are darkened that might be possible, but I thought I saw all yellow palpi. If black and using Nartshuk & Fedoseeva (2011), triangulina would fit. Fauna Ent, Scand mentions the lateral margins of the frontal trangle to be darkened, but that eludes me in your pictures. However, the genae do have scattered hairs.

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
