Zusammenfassung:Pratylenchus lentis n. sp. parasitizing roots of lentil in Sicily, Italy, is described and illustrated. The new species is characterized by a relatively high lip region with three annuli, mean stylet length of 16 mum, with anteriorly flattened knobs, cylindrical body with a relatively anterior vulva, large and ovoid spermatheca full of sperm, plump tail with truncate, irregularly annulated terminus, and by the presence of males. Molecular ITS-RFLP and sequencing analyses of the new species showed clear differences from other most morphologically similar species, such as P. thornei and P. mediterraneus. Preliminary host range tests revealed that chickpea, pea, faba bean and durum wheat are good hosts of P. lentis n. sp., whereas common bean, alfalfa and barley are less robust hosts and tomato, bell pepper, eggplant, melon and sunflower are poor hosts for the nematode
