Fenella monilicornis (Dahlbom, 1835)
So far known the mine cannot de distinguished from that of F. minuta, living on the same hostplant. The imago differs from that of F. minuta in having 14-16 antennal segments, rather than 12-14 (Hering, 1957a).
F. minuta has been found in Finland, where G. sylvaticum is unknown; probably therefore some other Geranium-species are suitable as well (Viramo, 1969a).
not known in the Benelux, not to be expected either.
