Moderately slender nematodes of small size. Body cylindrical, curved ventrad upon fixation, slightly tapering towards both extremities. Cuticle with two distinct layers, 2.0–2.5 µm thick at mid body and 3 µm on tail. Outer cuticle with fine transverse striations; inner cuticle distinctly striated; radial refractive elements abundant. Lateral, dorsal and ventral body pores indistinct. Lateral chords occupying about one-fifth of mid body diameter. Lip region slightly offset by a weak constriction, 1.5–2.0 times as wide as high and one-third of the body diameter at neck base. Lips amalgamated, with rounded contour; its inner portions transformed into a perioral disc. Amphid cup-shaped, opening at level of the cephalic constriction and occupying about two-thirds of the lip region diameter. Stoma a truncate cone. Odontostyle 1.2–1.5 times the lip region width long and provided with dorsal accessory piece covering the entire dorsal arm; its aperture one-fifth of the odontostyle length. Odontophore with basal knobs; 0.7–0.8 times the odontostyle length. Guiding ring simple, refractive, at 0.7–0.9 times lip region width from anterior end. Pharynx consists of a slender and weakly muscular anterior part separated from a cylindrical basal bulb by a depression, which occupies about 18.6–23.8% of the total neck length. Pharyngeal gland often visible. Cardia hemispherical, partially surrounded by the intestine. Nerve ring at 48–61% of the neck length. Genital system monodelphic-opithodelphic. Ovary reflexed, measuring 40–90 µm long; oocytes arranged in single row except near its tip. Oviduct joining the ovary subterminally, measuring 53–88 µm and consisting of a slender distal part and a poorly developed

. Weakly developed sphincter present at oviduct-uterus junction. Uterus short and tubular, measuring 25–37 µm; sperms not present in either uterus or oviduct. Anterior genital branch practically vestigial, almost always appearing as a small cell mass with inconspicuous lumen. Vagina cylindrical,

absent. Vulva apparently a transverse slit. Prerectum 3.4–4.7 times anal body diameter long. Intestine-prerectum junction guarded by three cells. Rectum 0.9–1.2 anal body diameter long. Tail cylindroid and relatively long; outer layer of cuticle thickened posteriorly forming a distinct hyaline layer.
