In North Dakota four new genera of plant parasitic nematodes were found: Ditylenchus, Hemicycliophora, Macroposthonia, and Nothocriconema. Twelve new species were detected in various plant associations. The species were Helicotylenchus digonicus, H. platyurus, H. pseudorobustus, H. varicaudatus, Macroposthonia raskiensis, Merlinius leptus, Nothocriconema permistus, Paratylenchus hamatus, P. vexans, Pratylenchus fallax, Tylenchorhynchus maximus, and Tylenchus vulgaris. Earlier reports of certain plant parasitic nematodes were confirmed. All plant parasitic nematodes reported in North Dakota are listed.
