Remarks (internal):It was not possible to study material on all recorded host species. The species is fairly common and widespread in Europe and Central Asia. It is, however, very rare in Japan (on Lonicera gracilipes var. glabra, TUAMH 2790). Some of the mentioned hosts are also known to be host species of M. magnusii.
