Hymenolepidoid Cestodes (Cyclophyllidae, Hymenolepidoidae) of Pratincole (Glareola Pratincola) from the South of Ukraine

Four hymenolepidoid cestode species Glareolepis porale (Meggitt, 1927) Spassky, 1967; Wardium (s. l.) tauricum Kornyushin et Greben, sp. n.; Wardium (s. l.) sp. n.; and Echinocotyloides longirostris (Rudolphi, 1819) Kornyushin, 1983 from pratincole from the Southern Ukraine are discribed. The morphology of G. porale is described in details. An interesting new observation is that testes are lacking in female proglottides of G. porale; the structures described in literature as testes in hermaphroditic proglottides are, in fact, ovarian lobes. The new cestode species Wardium (s. l.) tauricum sp. n. is described. It is characterised by aploparaksoid hooks, 13-15 μm long, and conical armed cirrus, 20-22 μm long. Another cestode species, Wardium (s. l.) sp., is identified to the generic level only. It differs from all the species of the genus in the size and armament of the cirrus; however, no scolex was present in the material studied.
