The species has a Holarctic distribution, and P. fuscipennis is already known as its host ( Fitton et al., 1988 ). Additionally Aubert (1969) recorded it as a hymenopterous parasite for Andricus (Cynipidae) , Pemphredon , Psen , Psenulus (Crabronidae) and listed Omalus as a possible host ( Torgersen, 1972 ). The present study confirms Aubert’s intuition. As in the case of M. acasta , P. septemcinctorius attacked both P. fuscipennis (2.1 % of cells) and O. sculpticollis (4.5 % of cocoons).
