Description (from Khan and Singh, 1974)
Body straight or only slightly arcuate on death. Body striation fine, lateral field originates in the region of median bulb, the number of incisures in the vulval region being 6 which gets reduced by fusion and only one extends upto the middle of tail. Lip-region conoid and low bearing three annules. Cephalic sclerotization strong extending up to two body annules. Spear 18 um long with slightly anchor shaped knob. Opening of the dorsal oesophageal gland located 3 um posterior to spear-base. Oesophagus typical of the genus. Isthmus about one corresponding body width long while length of the ventral oesophageal overlap is about 3 1/2 times the corresponding body width. One dorsal and two sub-ventral gland nuclei have been observed in the oesophageal overlap. Oesophago-intestinal junction located at 12% (11-13% in paratypes) of oesophageal overlap from its anterior end. Excretory pore located opposite the oesophago-intestinal junction, hemizonid anteriorly adjacent to excretory pore and extends upto three body annules. Vulva transverse slit, measures about 5/6 of vulval body diameter across. Spermatheca inconspicuous without sperms. Post uterine sac about one corresponding body width in length. Tail conoid over two anal body widths in length (1 1/2- 2 1/2 in paratypes) bearing 25 (24-30 in paratypes) annules. Tail tip crenate, phasmids located 18 annules anterior to tail terminus.
Male: Not found.
Type habitat and locality: Soil around potato roots at Ludhiana, Punjab.
Relationship: Pratylenchus teres comes close to P. crenatus Loof, 1960 from which it can be differentiated by the fine body annulations, the anterior location of vulva, straight shape of body when killed and by the presence of 6 incisures in the lateral field.
