N2 - A root-knot nematode, Meloidogyne duytsi n. sp., is described and illustrated from Elymus farctus (Viv.) Melderis from Dutch coastal foredunes. This new species is characterized by the following characters: female with styler slightly curved dorsally, 13.3 mu m long, with large transversely ovoid knobs set off from the shaft, asymetrical perineal pattern with a relatively low dorsal arch and coarse striae, lateral lines indistinct, and lateral wing present in most patterns, male with styler 19.8 mu m long, with large transversely ovoid knobs set off from the shaft, head region high and set off, labial disc slightly raised, lateral lips small, and tail conical with rounded tip, and second-stage juvenile 424 mu m long, with hemizonid anterior to excretory pore, tail 70.4 mu m long, tapering and slightly curved ventrally, and hyaline tail terminus distinct, 11.3 mu m long. A previously unknown malate dehydrogenase pattern and a slow esterase isozyme band were detected. M. duytsi n. sp. was also found in mixture with M. maritima Jepson, 1987 on Ammophila arenaria (L.) Link. [KEYWORDS: foredunes; Elymus farctus; Meloidogyne duytsi; morphology; root-knot nematode Arenaria l link; identification]
