Acalyptrate near water with arista plumose above, bare below normally indicates Ephydridae. Gymnomyzinae?

They do look similar, but they have significant differences in chaetotaxy. For instance, your specimen has a posterior notopleural bristle which is slightly closer to the lower margin of the notopleuron than the anterior one. In Hecamede, this bristle is more dorsal in position. Also Hecamede albicans (the sole European species) has milky wings and a large black protruberance in the middle of the face.

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
