Subspecies
Two subspecies have been
described, Hydrellia geniculata geniculata and Hydrellia geniculata
flavitarsis. However, the flavitarsis taxon is only known from
Sörbyholm, Sweden, which is also the type locality of the nominate
form. This co-occurence argues against a subspecific status of the
flavitarsis taxon. It is possible that the flavitarsus taxon represents
a separate Swedish species. However, I regard it more likely that the
flavitarsus is merely a color variant and include the name therefore in
the synonymy of the present species.

The species is recorded
from Central Europe (Austria, Germany), Italy, Sweden and Japan.
However, for Germany only a single record is available and this is
regarded as doubtful by Stuke (2011).
