Remarks. There is no difference between the Iranian population of P. t e re s (Azimi & Mahdikhani–Moghadam 2013) and the original description (Khan & Singh 1975). It is characterized by having a labial region with three annuli, lateral fields with six lines; outer ones being crenate, their number six in vulval region reducing to one at middle of the tail, stylet 16–18 µm long, spermatheca indistinct and empty, and a conoid tail with annulated tip (there are 22–30 annuli on the ventral side of the tail). It is morphologically close to P. crenatus from which it differs by the fine body annulations, the anterior location of the vulva and presence of six lines in lateral fields.
