during a survey, five known species of plant-parasitic nematodes of the families tylenchidae and dolichodoridae (tylenchomorpha: tylenchoidea) were collected and identified from several locations in golestan, guilan, kurdistan, and fars provinces. paratrophurus kenanae, tylenchus elegans and t. ritae, as new records for iranian nematode fauna, with the two previously reported species filenchus butteus and tylenchorhynchus leviterminalis are illustrated and described. the similarity of several species of paratrophurus with those of the closely related genus, tylenchorhynchus, is also discussed.
