Hi Nikita, Geomyza yes; tripunctata no! This is a member of the "combinata group". Although Geomyza combinata is no longer in use as a species name, it is tempting to still call the species group "combinata group". My guess would be Geomyza hackmani, however it is difficult to be sure after a picture. Studying the genitalia would get you a positive identification. Please collect material like this! I am always very interesting in studying it!! Jan Willem |

Hi Nikita, GOOD that you collected the specimen  .As far as I know there are no online keys to Opomyzidae, so sorry, no link. Are you sure that Geomyza combinata is not in your key? I can hardly imagine that! Literature to use: Carles-Tolr?, M. 1993. Tri novych vida sem. Opomyzidae (Diptera) iz Ispanii [Three new species of the fam. Opomyzidae (Diptera) from Spain].
