Description (from C.I.H. Descriptions of Plant-parasitic Nematodes)
 Female: Body moderately slender, almost straight when killed by gentle heat.  Cuticular annulation fine.  Lateral field normally with four incisures, outer bands may be partly areolate, central field sometimes with oblique striae near vulva, becoming areolate behind vulva, not extending to tail tip.  Lip region slightly set off, low, flat in front, with rounded outer margins, 3 annules.  Head with strong, conspicuous skeleton.  Basal knobs of spear broadly rounded, sometimes cupped anteriorly.  Oesophagus overlapping intestine ventrally in a lobe about 1.5 body-widths long.  Excretory pore about opposite oesophago-intestinal junction with hemizonid occupying about two body annules immediately in front of it.  Post-uterine sac short, undifferentiated, about 1 or 1.5 vulval body-widths long.  Spermatheca spherical, or nearly so.  Tail generally rounded, tip smooth, with 15-27 annules on ventral surface.
 Male: Common.  Slightly smaller than female, but similar in form.  Lateral field with four incisures ending on the bursa, occasionally with oblique lines in central field near mid body.  Spicules slender, with well-marked manubria and ventrally arcuate shafts, 14-17 um long; gubernaculum simple, 3.9-4.2 um long.  Tail about twice as long as anal body diameter; bursa irregularly crenate along edge, enveloping tail tip.
Type host and locality: Greenhouse soil, Rhinebeck, New York, USA

Descriptions (from Sher & Allen, 1953)
    Female: Lateral field marked by four incisures.  Lip region slightly set off from head bears three annules.  Outer margins of heavily sclerotized labial framework extend into the body about one body annule.  Spear-guiding apparatus extends posteriorly from basal plate about three body annules.  Spear 18 um long, well develoed, broadly rounded basal knobs.  Dorsal esophageal gland orifice about 2 um behind spear base.  Esophagus opens into intestine near level of excretory pore.  Hemizonid about two annules long situated about one annule in front of excretory pore.  Ovary does not extend to esophagus consists of a double row of oocytes except for posterior and anterior end which is single.  Spermatheca round, oviduct cellular about twice as long as spermatheca, uterus about as long as spermatheca.  Posterior uterine branch short, about equal to the width of body at vulva.  Phasmids slightly posterior to middle of tail.  Four lateral lines extend past phasmid.  Tail rounded, no striations around terminus.
    Male: Similar to female.  Single outstretched testis consists of spermatocytes arranged in double row.  Phasmids slightly posterior to middle of tail, extend only slightly into bursa.  Spicula arcuate, hafted, rest upon trough-shaped gubernaculum.
Type host: From greenhouse soil.
Type locality: Rhinebeck, New York.
