Description

Female Body ventrally curved upon fixation more strongly in posterior half. Cuticle finely striated, its thickness on body 3 μm and on tail tip 4 um. Dorsal, ventral and lateral body pores indistinct.

Lip region slightly set off from body, somewhat angular in contour, about l /6 th of body-width at base of oesophagus. Amphids stirrup-shaped more than half as wide as lip-width. Odontostyle 25 μm or 2- 7 head-widths long. Guiding ring 1.5 head-widths from anterior end of body, wall of stoma anterior to guiding ring thickened. Odontophore linear, not flanged, 29 μm or 3.2 headwidths long.

Basal expanded part of oesophagus occupying about 41 % of neck length. The location of the oesophageal gland nuclei and their orifices as given in Table III. Nerve ring surrounding the anterior slender part of oesophagus at 50% of neck length from anterior end of body. Cardia rounded, surrounded by intestinal tissues. Prerectum 2.7 and rectum about one anal body-width long.

Vulva a transverse slit, vagina extending inwards less than one half of corresponding body-width and distinctly sclerotized. Gonads amphidelphic. A well developed sphincter present between uterus and oviduct. Uterine egg measures 82><23 μm. Ovaries reflexed, oocytes arranged in a single row.

Tail conoid, ventrally curved, 1.5 anal body-widths long with two UCI caudal UUCIJ ‘ \cores JULÇÖ on Ull each CGVU side.

Male Supplements an adanal pair and 5 ventromedians, spaced as in Fig. 5, I. The posterior three more closer together than the others. Spicules 40 μm or 1.7 anal body-widths along median axis, stout, heavily selerotized with lateral guiding pieces. Copulatory muscle bands occupying the area up to the last ventromedian supplement. Prerectum begins after the last ventromedian supplement.

Habitat and locality. Soil around roots of ferns from Nainital, Uttar Pradesh.

Remarks The specimens for this study were taken from the Nematode Collection of the Department of Zoology, Aligarh Muslim University
