Dimensions:

Females (5): L= 1.13- 1.34 mm; a = 23-28; b =4.5-5.0; c = 46-56; V = 5 l-53; G1 = 18- 21; G 2 = 177 20.

Males (3): L = 1.16-1.46 mm; a =26-30; b = 4.9-S.2; c =Sl-56; T= 63-74; s picules=46.-48 pm.

Description:

Female: Body ventrally curved upon fixation, tapering slightly towards extremities, curvature more pronounced in posterior. part of body. Cuticle 晩湥汹縠 striated, 2 pm 繨楣欠 on body,. 7- 10 pm on tail tip. Dorsal, ventral and lateral body pores indistinct.

Lip region distinctly set otT from body, Ij4th as wide as body ~t base of oesophagus. Amphids cup-shaped wit~ slit-like apertures occupying about 2/3rd of corresponding body width. Odontostyle 20-23 tlm o~.! 1.6-J.7 head-widths long with an aperture about 1 /8th of its length. Guiding ring 1.0-1.2 head-widths from anterior end. Odontophore 22-26 ttm or 1.1- 1.3 times. the odontostyle length with very small swellings at its base. Maximum width of swellings 3-4 pm.

'Basal expanded part of oesophagus occupies about 37-40% of neck length. Location -of oesophageal gland nuclei and their orifices as given in Table III. Nerve ring surrounding anterior slender part of oesophagus at 45-50% of neck length from anterior end of body. Cardia henlispheroid, 8-10 ILm long, surrounded by intestinal tissues. A well developed oesophago-intestillal disc present. Prerectum 3.6-3.9, and rectum 1.0- 1.2 anal body-widths long.

.

Vulva a transverse slit. Vagina extending l /3rd across the body, encircled proxirnally by cuticularizatioñ and distally by sphincter a muscles. Gonads amphidelphic amphidelphic.. Uterus divided into a proximal glandular and distal muscular part. Ovaries reflexed, oocytes arranged in in a sin single gl@ row except in growth region.

Tail 0.6- 1.2 anal body-widths long, bluntly conoid or hernispheroid with with two caudal pores on each side.

Male Supplements an adanal pair and 9- 10 ventromedians, the latter irregularly spaced. Spicules about 17-1.8 anal body-widths along median axis. Lateral guiding pieces well developed, 8-9 μm along median axis. Copulatory muscle bands occupying the area up to last ventromedian supplement. Prerectum starts from second ventromedian supplement, about 3.5--3.8 anal body-widths long.

Habitat and locality Soil around the roots of wild fruit tree, near Degree College, Lansdowne (altitude approx. 1,415 m), Uttar Drarlpeln Remarks E. parateres was described by Baqri & Jairajpuri (1974) from *soil around roots 'of weeds and mosses from Manali, Himachal Pradesh. The present specimens were collected from soil around roots of wild fruit trees from Lansdowne, Uttar Pradesh. They agree fairly well with the description of E. parateres as given by Baqri 8L Jairajpuri (1974). However, there are minor Variations in body dimensions of these specimens. The length of odontostyle is 20-23 μm (21-22 μm) while the length of odontophore is 22-26 (23-23 μm) in these specimens. The number of ventromedian supplements is 9- 10 (7).

The values in parentheses are of the type specimens of E. parateres as given by Baqri & Jairajpuri.
