Dimensions| \ Females (n = 4) L = 1.48 - 1.71 mm; a = 24- 29; b = 4.2 - 5.1 1; C = 50 - 55; 1 V = 12 - 1848_4915- 21_ Female, holotype: L = 1.67 mm; a = 28; b _ 5.1 1; C = 5 31 1 V = 174917. 7 Males (n = 5) L _ 1.54 - 1.85 mm; a _ 28 - 57; b _ 5.4- 5.8 (n _ 5) c = 26- 54. Body moderately slender, curved into C-shape in death. Cuticle 3.f-Lthick, smooth externally, with very fine transverse striation internally. Lateral chord finely granular, one-fifth to one-sixth of body width. Lip region one-quarter as wide as body at the base of the oesophagus, offset by depression, about twice as wide as high; the inner papillae project distinctly, the outer ones hardly. End-on view shows there are six lips with the usual 6 + 10 papillae. Amphids stirrup-shaped, more than half as wide as lip region. Spear length 40-43, ?? in the male, 42-46 tt in the female, or 3.0-3.8 X width of lip region. Spear 2 tt wide, with aperture about 1/15-1/20 of spear length. Spear curved very slightly to dorsal side. Extensions about as long as spear proper, linear, not forming flanges. Guiding ring double. Walls of mouth cavity not so conspicuously thickened anterior to guiding ring as in many other species of the genus. In some specimens the oesophagus narrows slightly where it passes through the nerve ring, which surrounds it about its middle. Oesophagus widened at 60% of neck length from head end, the posterior part slightly more than half as wide as body and about 3.5 X as long as wide. Hemizonid not observed. Cardia triangular to elongate-conoid.
Female. Vulva a transverse slit. Vagina less than one-half body width deep, with conspicuous sclerotization. Gonads paired, opposed and reflexed. A distinct constriction between uterus and oviduct. Ovaries proper short. Scattered sperm in the uteri. Tail 1.3-1.8 anal body diameters long, conoid, curved to ventral side. Rectum about as long as anal body width; prerectum apparently as long as rectum in two specimens, nearly thrice as long in another.
Male. Testes two. Spicules paired, blunt-tipped, 53-56 ti long (measured along their axis), with lateral guiding pieces. Besides the adanal pair there is a row of seven (n = 2) or eight (n = 3) ventromedian, spaced supplements, occupying together three tail lengths; the posterior one lying two tail lengths anterior to the anus. Prerectum three body widths long. Tail 1.5-1.8 anal body widths long, shaped as in female.
Holotype. Female on slide WT 687 of the Nematode Collection of the Plantenziektenkundige Dienst, Wageningen, Netherlands. Paratypes: three males (one with end-on view of head) and two females on slides WT 688-691 of the same collection; two males and one female in the collection of the Zoological Museum of Aligarh Muslim University, Aligarh, U.P., India.
Type habitat and locality. Soil around roots of grass (identity not determined), Nainital, U.P., India.
