SOME SPECIES OF Paratylenchus (NEMATODA: TYLENCHULIDAE)

After studying of the plant parasitic nematodes, collected from different plants and regions of Iran, seven species belong to Paratylenchus, including P. arculatus, P. colinus, P. conicephalus, P. neoprojectus, P. similis, P. straeleni and P. veruculatus were identified. Among them, P. colinus, P. neoprojectus and P. veruculatus are new records for Iranian nematode fauna that full description of them and also that of P. straeleni were given. These species were collected and identified from different hosts and localities as follows: P. colinus from the rhizosphere of apple trees in Divandareh, Kurdistan province, P. neoprojectus from both shade-trees in Tabriz and apricot seedlings in Sanandej, and P. veruculatus from sugarcane fields of Khuzestan province. Furthermore, a dichotomous key for identification of Iranian species of this genus was presented
