Host: Lanius excubitor excubitor Linnaeus, 1758.
Ref.: Balát (1977); Szczykutowicz et al. (2006) as Brueelia cruciata (Burmeister, 1838); Gustafsson & Bush (2017); this paper.
Locations: Slovakia (Balát 1977); NE Slovakia (Szczykutowicz et al. 2006); Hniezdne, 25 Mar. 1964 (Weisz Coll., VETUNI).
Notes: Balát (1977) recorded this species from Slovakia without a host association. Since this species parasitises Lanius excubitor only (Price et al. 2003: 155), it is most likely that Balát’s (1977) record refers to this host association.
