New data on helminths of the woodcock <i>Scolopax rusticola</i> (Aves, Charadriiformes) in the middle Volga region (European Russia)

The helminth fauna of the Eurasian woodcock Scolopax rusticola was studied in the territory of Mordovia (European Russia) for the first time. Twenty-five specimens of waders were examined using the incomplete helminthological necropsy in April 2019, 2020, 2022. Nine helminth species were found in woodcocks: Lyperosomum alaudae, Scolopacitrema cubrensis, Anomotaenia clavigera, Fuhrmannolepis scolopacina, Aploparaksis pseudofilum, Dispharynx nasuta, Hadjelia truncata, Tetrameres dubia and Agamospirura macracanthis, juv. Among them the trematode L. alaudae, nematodes D. nasuta, H. truncata and A. macracanthis, juv. were recorded in S. rusticola for the first time. We provide morphological descriptions and photos of these parasites.
