I do not have a key to European genera. The key to Nearctic genera of Cecidomyiidi (https://www.mapre...a.4392.3.1) depends on characters that are difficult to see in photos. For example, after determining this is Cecidomyiidi but not Asphondyliini I reach

85. Head with occipital protuberance, bearing two prominent, anteriorly-directed setae (setae often lost in preparations but sockets remainprominent) ... 85
85. Head lacking occipital protuberance (figs 21–23) ... 147

You seem to have a female based on the form of the antennae. Many genera require males for confident identification.

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
