Description (from Singh and Jain, 1984)
Body straight or slightly curved, tapering at extremities.
Cuticle finely annulated, annules 1.2-1.3 um apart. Lateral
fields 1/3 of the body width, with 4 incisures, outer ones crenate and
continue up to tail tip. The middle incisures unite just about the
phasmids which lie in anterior half of the tail. In two specimens
later fields were found with 7 incisures. Head with 3 annules,
continuous, 6-8 um wide and 2-4 um high. Cephalic framework
strongly sclerotized, extending posteriorly up to 1-2 body annules.
Spear well developed; metenchium slightly shorter than or equal to telenchium;
basal knobs cupped, 4-4.5 um cross. Orifice of dosal oesophageal
gland 2-3 um form spear base. Procorpus cylindrical, 29 (20-40)
um
long. Median oesophageal bulb slightly elongate or almost spherical,
12-14 X 9-12 um. Oesophageal glands 32 (30-37)
um,
overlap intestine ventrally more than one body width as a long narrow lobe.
Nerve ring surrounds the isthmus less than 1/2 the bulb length behind the
bulb, 63 (58-68) um from anterior end. Excretory pore 77 (70-86)
um from anterior end, posterior to nerve ring. Hemizonid 2
annules wide, just anterior to the excretory pore. Hemizonian one
annule wide, 7 annules posterior to Hemizonid. Oesophago-intestinal
junction at the level of or slightly posterior to the excretory pore.
Vulva a transverse slit. Vagina at right angle to the body
axis, 7-10 um long, about 1/3 of vulval body width. Reproductive
system monodelphic, prodelphic and outstretched. Oocytes arranged
in a single row. Spermatheca oval, filled with sperms. Post-vulval
uterine sac short, 20 (14-26) um long, about one body width or less
or 19-32 percent of the distance between vulva and anus. Distance
between vulva and anus 75 (70-85) um, more than twice the tail length.
Tail subcylindrical; 28.8 (24-35) um long, with 21 (20-22) annules
and ending in a truncate or slightly rounded terminus.
Male: Similar to female except that the body is slender
and smaller and spear slightly shorter. Testis single, outstretched
with spermatocytes arranged irregularly. Spicules paired, arcuate.
Gubernaculum thin, rod like. Bursa crenate, arising one spicule length
anterior to cloaca and enveloping the tail completely. Tail conoid
with acute terminus. Phasmids in the anterior half of the tail.
Habitat: From within the roots of garden croton (Codiaeum variegatum).
Locality: Charbagh, Lucknow, India.
Relationship: The new species comes close to Pratylenchus
penetrans (Cobb, 1917) Filipjev and Schuurmans Steckhoven, 1941, and
P. subpenetrans Taylor and Jenkins, 1957.
