SIN = 80.1 (76-83); Sp = 90.6 (88-95); SlN = 89.9 (88-93).

Male (n = 1): L = 1.00 mm; maximum body width = 41 Ilm; body width at cloacal opening = 28 Ilm; odontostyle = 13 llm, odontophore = 24 llm, total stylet = 37 Ilm; oesophagus = 237 Ilm; tail = 221lm; a = 27; b = 4.2; c = 46; c' = 0.8; spicule along arc = 45 Ilm.

DESCRIPTION

Female: Body slightly ventrally arcuate. Cuticle about 1.5-2 Ilm thick, unstriated. Lip region 12- 13 Ilm wide, offset, although the degree depends on microscope focusing because of large angular cephalic papillae. Lip papillae large, dome shaped. Amphidial aperture 5-7 Ilm. Guiding ring double; 8-9 Ilm from anterior end. Odontostyle about 1.5 Ilm wide, the ventral side posteriorly forked but the dorsal not so when viewed laterally. Odontostyle 1 -1.2 and total stylet 3-3.2 of head width long. Intestinal wall cells filled with green or yellowish-green granules, but not the lumen of intestine. Cylindrical crystals seen in intestine of one female, near junction of intestine and prerectum. Vulval cuticularized plates more or less rounded, indistinct, not much refractive. Female tail with two papillae on each body side. Cuticle 6-7 Ilm thick on tail end.

Male: Adcloacal pair of papillae and 9 ventromedian supplements. The distance between cloaca and SI = 26 Ilm, SI-Sl = 12 Ilm; Sl-S3 = 19 Ilm; S3-S4 = 19 Ilm; S4-SS = 20 Ilm; SS-S6 = 221lm; S6-S7 = 20 Ilm; S7-SS = 24 Ilm; and SS-S9 = 18 Ilm. Four ejaculatory glands at each body side distinct.

REMARK

The male of E. laevis was not known, and the examined specimen fits weil to the described as E. knuppenburgensis Altherr in Altherr & Delamarre Deboutteville, 1972. Altherr mentioned ten supplements, which is not considered distinctly different From nine observed herein. Therefore, the two species are synonymized. Their possible identity was already suggested by Altherr.
