Is this Eccoptomera filata? If I understood correctly, E. longiseta should have a red-brown third antennal segment, which I don't see here, so I went for a different species. But there are other species I don't know how they look like.

Vienna, mid October

Eccoptomera filata
Eccoptomera infuscata
Eccoptomera longiseta
Eccoptomera microps
Eccoptomera obscura
Eccoptomera ornata
Eccoptomera pallescens

Yep! It should be E. longiseta ;)

Coming back to this specimen, my ID is solely based on a 1932 paper, regarding the statement that longiseta has a 'red-brown 3rd antennal segment'. I would call the color here rather yellow or light-brown. In the gallery, both species seem to have darker antennae then my specimen, but don't know whether these are light effects.
Any key for this genus available?

In seiner Monographie der Helomyziden Czerny (1924) schreibt:
"Fühler entweder ganz rotgelb oder das dritte Glied in verschiedener Ausdehnung gebräunt" ;)

Great, I now worked with his monography and used chaetotaxy instead of color descriptions. Can confirm E. longiseta.
