F e m a l e s. Trunk 32.48–42.00 (35.70) mm long, with maximum width at anterior part 860–1800 (1186).

Proboscis of this species is armed with 30–34 longitudinal rows of hooks, 16–17 hooks in a row according to Petrochenko (1958) and Khokhlova (1986). Among them, the first 5–7 hooks are large, with well-developed roots. In the description of Dimitrova and Gibson (2005) which was based on the material from the Natural History Museum (London) from Strix aluco of the United Kingdom , 28–29 longitudinal rows of hooks were indicated, 14–15 hooks in a row, of which the first 4 hooks were large with developed roots. Our material is similar to the specimens described by Dimitrova and Gibson (2005) . The species was described from birds of prey in Europe. It is recorded from birds of the genera Accipiter , Buteo , Strix , Otus , Circus , Haliaetus , Milvus in Europe and Asia. It is found in Ukraine in western marsh harrier Circus aeruginosus 1 , common kestrel Falco tinnunculus 1 , brown owl Strix aluco 2 , ural owl S. uralensis 2 in Zakarpattya Region (Rahiv District — Luch, Lazeschina, V. Bychkov, Ch. Tysa, Tyachiv District — Kireshi), IvanoFrankivsk Region (Nadvornyansk District, Losva), Volyn Region (Lyubeshyv District, Nevir), Dnipropetrovsk Region (Pankovka) ( Ivanitzky, 1940 ; Khohlova, 1986 ; Lisitsyna, 1993 , 2008 , 2014 ).
