Description

Female Body ventrally curved to C-shaped upon fixation, tapering gradually in neck region. Cuticle finely striated, its thickness 2-4 μm on body,_ 5-6 μm on tail. Dorsal, ventral and lateral body pores not distinct.

Lip region set off from body by a slight depression, about 1 /4th body-width at base of oesophagus and about twice as wide as high. Amphids cup-shaped with slit-like apertures. Odontostyle 43 -48 μm or 3.7-4.0 head-widths long; its aperture l /21 - 1 / 16th of its length. Guiding ring 1.6- 1.8 head-widths from anterior end of body. Odontophore linear without flanges, nearly as long as odontostyle.

Basal expanded part of oesophagus occupying 29-31 % of neck length. Location of oesophageal gland nuclei and their orifices as given in Table III. Nerve ring turrounding anterior slender part of oesophagus at 45 -50% of neck length from anterior end of body. Cardia hemispheroid, surrounded by intestinal tissues. Prerectum about three and rectum about one anal body-width long.

Vulva a transverse slit, extending ~l/3-l/2 across the body, encircled proximally-by conspicuous sclerotization. Gonads amphidelphic. Uterus divided into a proximal glandular and a distal muscular part. Oviduct and uterus distinctly separated by a sphincter. Ovaries short, reflexed, oocytes arranged in a single row except in growth region.

Tail 1.5- 1.7 anal body-widths long, conoid, bent ventrally and provided with two caudal pores on each side.

Male Supplements an adanal pair and seven ventromedians spaced almost at regular intervals. Spicules 48 μm or 1.5 anal bodywidths along median axis. Lateral guiding pieces present. Copulatory muscle bands occupying the area up to the last ventromedian supplement. Prerectum begins after the last ventromedian Supplement and is about five anal body-widths long.

Habitat a-nd locality Soil around the roots of unidentified grasses from Nainital, Uttar pradesh.

Remarks The present study is based on specimens from the Nematode Collection in the Department of Zoology, Aliigarh Muslim University.
