Thread subject: Diptera.info :: Lauxania minor or cylindricornis ?

I have photos of a similar female and i thought about this genus (Lauxania).

Shatalkin's keys mention "Basal part of wing darkened" for L. cylindricornis. I do not see a complete ring of darkness at the base of the wing on L. minor photos. So is this a reliable feature for separating the two species?

Best wishes,
John
