Material examined. Lkor : Sodankylä, Muotkanmaja, 1989, V. Vikberg ( 1 ♀ , VVCT ). Remarks. This specimen was reared from an egg of a sawfly from the Pontania dolichura species group ( Hymenoptera : Tenthredinidae ) on Salix glauca . Galls were collected on 6.vii.1989 (rearing number 17/1989 VV ). One gall contained no larva of the host, and one female mymarid emerged from the egg. It was mounted in euparal by V. Vikberg and initially identified to the former A. fuscipennis species group of Anaphes by S. V.Triapitsyn in 2017. Unfortunately, the specimen has only one complete antenna which is somewhat shriveled, so it is impossible to count mps on the funicular segments with any confidence; thus, its positive identification is impossible. Otherwise, this specimen mostly resembles those specimens of A. ( Anaphes ) ovipositor ( Soyka, 1946 ) which have 1 mps on F4 of the female antenna. It is definitely not A. ( Anaphes ) crassipennis ( Soyka, 1946 ) .
