摘要
Uliginotylenchus changlingensis n. sp. is described from the rhizosphere of potato roots in Changling county, Jilin province, China. The species is characterised by a long body (female: 846-952 mu m, male: 785-934 mu m), completely areolated lateral field with three incisures, high and rounded offset lip region bearing five or six annuli, long stylet (female: 24.0-26.0 mu m, male: 23-28 mu m), presence of vulval flaps, female tail subconoid with 28-39 annuli and terminus bluntly conoid without striations, distinct phasmids and gubernaculum distally crescent-shaped. It is closely related to U. cylindricaudatus and U. bifasciatus. It differs from U. cylindricaudatus mainly by the different number of labial annuli (5-6 vs 7-8), different tail shape (subconoid vs subcylindrical) and by vulva] flaps present vs absent. It differs from U. bifasciatus mainly by different female stylet length (24-26 vs 19-20 mu m), tail shape and annuli (subconoid with 28-39 annuli with smooth terminus vs subcylindrical with 42-48 annuli with annulated terminus). It further differs from other species of Uliginotylenchus by the offset vs continuous labial region.
