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.
