Heleonomus macilentus (Nitzsch [in Giebel], 1866)

Host: Grus grus (Linnaeus, 1758) .

Ref.: Balát (1977).

Location: Slovakia (Balát 1977).

Notes: Balát (1977) recorded Heleonomus macilentus from Slovakia without a host association. Considering that Grus grus is the only host for this louse species in Europe (Price et al. 2003: 110), we believe that Balát’s (1977) record is also from this species of crane in Slovakia.
