Four nematode species of the infraorder Tylenchomorpha namely Paratylenchus microdorus, Filenchus hamuliger, Psilenchus aestuarius and Tylenchus arcuatus collected from the rhizosphere of different plants in Khouzestan province, southwestern Iran, andcharacterized morphologically and morphometrically. The recovered population of P. microdorus is characterized by its 268-386 µm long body, 13-17 µm long stylet and rounded tail terminus. Iranian population of the F. hamuliger is characterized by having two lines in the lateral field, truncated conical head, 8-10 µm long stylet, axial spermatheca and hook-shaped tail terminus. The population of P. aestuarius is characterized by lacking of annuls on head region, having of post anal sac and clavate tail, and finally, the studied population of T. arcuatus is characterized by its 652-809 µm long body, continuous annulated head, elongate conical hooked tail with sharp or slightly rounded terminus. The three species F. hamuliger, P. microdorus and T. arcuatus are new records for the Iranian nematofauna.
