ABSTRACT
The present study provides the morphological and morphometric characterization of some plant parasitic nematode populations, recovered from agricultural fields during surveys of the districts Gilgit and Nager, Gilgit-Baltistan, Pakistan. The analysis of samples yielded a new nematode species and two new reported species belonging to the order Tylenchida as new geographical records for Pakistan. Hemicycliophora pyri n. sp., is characterized by the broadly rounded lip region with two indistinct annuli, closely fitting sheath with 231-247 body annuli, stylet 95-100 µm long, non-raised and non-separated labial disc and gradually tapering long tail. Psilenchus vincigurrae Brzeski, 1991and Ditylenchus equilis Heyns, 1964 have been reported as new record species from Pakistan. These species are described and briefly re-described along with their morphometric data, photomicrographs and illustrations.
