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.
