If it is under 2 mm long it could be Corynoneura or Thienemanniella, both in subfamily Orthocladiinae.

Fore trochanter with dorsal keel; apex of hind tibia enlarged ... Corynoneura
Fore trochanter without dorsal keel; apex of hind tibia usually not enlarged ... Thienemanniella

Hi John! TumbsUp

Thanks agains.

It's well smaller than 2mm, 1,2mm to be exact.
I will look into the difference between the 2 genera. That will be more difficult.

A nice festive season!!! Smile

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
