G e n e r a l (2 {, 4}). Trunk elongate, almost cylindrical. Proboscis divided into 2 parts by constriction at level of receptacle attachment. Anterior proboscis part spatulate or spherical, posterior proboscis part conical. Neck short. Proboscis with 30–32 longitudinal rows of 16–18 (17) hooks. First 4–6 (5) hooks large with posteriorly directed strong roots. Next 3–4 hooks transitional, with roots consisting of 2 antero–lateral alate processes, remaining hooks spiniform with simple roots directed anteriorly. Length of blade increasing from first to third, then gradually decreasing, blade of transitional hooks smallest. Roots increasing from first to 4–5th, roots of transitional hooks smallest. Proboscis receptacle double-walled, attach in middle proboscis, formed constriction. Lemnisci sacciform, longer than proboscis receptacle. Gonopore subterminal in both sexes.

R e m a r k s. The species was described from barred owl Strix varia Barton, 1799 in North America ( Van Cleave, Pratt, 1940). Our material corresponds to the first description ( Van Cleave et Pratt, 1940).
It is recorded from the birds of the genera Strix , Aquila , Otus , Athene , Asio in the Volga region and Asia ( Turkmenistan, Tajikistan). It is found in Ukraine in hen harrier Circus cyaneus 2, eagle-owl Bubo bubo 2 in Donetsk Region (Strilzovska Step Reserve) ( Lisitsyna, 1993).
