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

Looks rather like Diclasiopa (Ephydridae)

In the gallery, ephrydids from Hecamede spp. are also alike…

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.
