- Moderately slender nematodes, 2.17-2.70 mm long.
- Cuticle three-layered, ranging from 2.5-4.0 μm thick in anterior
region to 5.0-8.5 μm on tail, very fine transverse striation,.
- Lateral chord occupying 18-30% of mid-body diam.
- Lip region slightly offset by a shallow depression, 24-32% of
body diam. at neck base.
- Amphid fovea funnel-like, its aperture 52-60%) of lip region
diam.
- Cheilostom nearly cylindrical, lacking any differentiation.
- Odontostyle robust, 4.0-4.9 times as long as broad, 1.1-1.3
times longer than lip region diam., with aperture occupying 52-67%
of total length. Guiding ring simple.
- Odontophore simple, rod-like, 1.5-1.8 times longer than
odontostyle.
- Esophagus muscular, enlarging very gradually to basal expansion
> 50% of total length.
- Cardia conical, 21-34 × 20-30 μm.
- Tail convex-conoid with broadly rounded terminus, its inner
cuticle layer visibly refractive and separated from outer layer by
an empty space (lacuna). Caudal pores two pairs, both subdorsal, in
posterior half of tail.
Female:
- Genital system didelphic-amphidelphic, with both branches
equally developed, anterior.
- Ovaries usually reflexed beyond oviduct-uterus junction.
- Uterus a simple, tube-like structure filled with abundant sperm
cells.
- Vagina extending inwards for 48-60% of body diam., with
cylindrical pars proximalis, pars refringens consisting of two
adjacent trapezoidal sclerotised pieces and pars
distalis weakly developed,
- Vulva a short, moderately sunken, transverse slit.
- Prerectum 1.2-1.7, rectum 1.0-1.3 anal body diam. long
