Goniodes tetraonis (Linnaeus, 1761)

Host: Lyrurus tetrix (Linnaeus, 1758) .

Ref.: Straka (1987).

Locations: Oravská priehrada pri Námestove, 1 May 1977; Oravský Podzámok, 1 May 1977; Sučany, 2 May 1977; Ratkovo, 6 May 1977 (Straka Coll., AKMM).

Notes: Straka (1987) recorded Tetrao urogallus and a hybrid between T. urogallus and Lyrurus tetrix as hosts of Goniodes tetraonis . It is known that T. urogallus and L. tetrix can produce hybrids in wild populations (Kleven et al. 2020), so finding lice on such a hybrid is both unusual and interesting. However, considering that T. urogallus is a natural host of Goniodes bituberculatus Rudow, 1869 (Price et al. 2003: 331; see above), the association between Goniodes tetraonis and T. urogallus is, in our opinion, questionable and most likely the result of contamination or straggling.
