Morphology and Anatomy:

.

Female:  

  • Moderately slender to slender, 0.97-1.35 mm long.
  • Body cylindrical, tapering towards both extremities; tail is conical.
  • Cuticle two-layered, tylencholaimoid; outer and inner layer of cuticle with distinct transverse striation.
  •  Lateral chord one-third to one-fourth of body diam. at mid-body; hypodermal glandular bodies present:
  • Lateral body pores distinct, arranged in double or single row.
  •  Lip region offset by a weak constriction, somewhat broader than adjoining body.
  • Lips mostly amalgamated, inner and outer labial papillae button-like; cephalic papillae without surrounding annulus.
  •  Amphidial fovea stirrup-shaped, their aperture 40-60% of lip region diam.
  • Cheilostom longer than broad, with relatively thick walls.
  •  Odontostyle dorylaimoid, straight, length 0.8-1.2 lip region diam., aperture 50-59% of total length.
  • Guiding ring simple, 0.4-0.5 lip region diam. from anterior end.
  • Odontophore linear, rodlike, 1.4-1.7 times as long as odontostyle.
  • Esophagus slender, muscular,  gradually enlarging anterior section with basal expansion 45-52% of total length.
  • Nerve ring encircling anterior slender part of esophagus at  31-37% of total esophagus length.
  • Cardia rounded conoid, 7-18 × 7-16 μm. A dorsal cellular mass 25-40 μm long always present near esophagoo-intestinal junction.
  • Genital system didelphic-amphidelphic, with both branches equally developed; ovaries reflexed, with oocytes arranged first in two or more rows, then in a single row.  Oviduct-uterus junction with a weak sphincter.
  • Uterus a simple tube, 0.6-1.2 body diam,  Vagina extending inwards 30-50% of body diam., pars proximalis 9-14 × 5-8 μm, surrounded by weak musculature, pars refringens absent, pars distalis 2.5-4.5 μm long.
  • Vulva pore-like.
  • Prerectum 1.5-3.6, rectum 0.8-1.5 anal body diam. long.
  • Tail conical with rounded tip, dorsally convex, occasionally slightly subdigitate. Two subdorsal pairs of caudal pores.
