 abstract={The ant Myrmica karavajevi is an extremely rarely found and poorly known workerless social parasite of ants of the Myrmica scabrinodis species group. Hereafter detailed information of its previously published findings from four geographical regions in Poland (Bieszczady Mts, Pieniny Mts, Pomeranian Lakeland and Mazovian Lowland) as well as data on three new records from the Roztocze Upland, Lubelska Upland and Krakowsko- Częstochowska Upland is given. The latter suggests higher than hitherto suspected degree of host species infestation by M. karavajevi. Use of M. rugulosa as a host by M. karavajevi is also discussed.},
