Hi, this little Sciarid was found in my house, in a terrarium with coconut-soil in it - currently only collembolas inhabit it. I spotted 2 male and one female Sciarids, around 4 mm long in the terrarium and cought a male. Using a microscope, I tried to identify it from Manual of palaearctic diptera. My guess is
Chaetosciara (one european species, C. estlandica). Can anyone check and correct my assumption?

And a rather useless picture of terminalia from side:)

I need to see if the fore tibia has a comb, but I think this is a
Bradysia.

Thank You a lot, I made some images of fore tibia. I think the comb should be where the arrows are, right? I don't really see a comb but something brown is definetly visible. My other guess was also Bradysia :) At least they are close to each other in the key.

Yep - that's the right area; the comb is fine and transparent, and not in the same plane as the other bristles. Another possibility ,as this was in "soil" is
Lycoriella. These tend to be frequent contaminants.
