Morphology and Anatomy:

Female:

  • Monodelphic-prodelphic, located on the right side of the intestine.
  • Ovary without flexure posterior to vulva level. Oviduct short, less than a half of the corresponding body diam.
  •  Post-vulval uterine sac 0.7-1.0 times longer than the corresponding body diam.
  • Vagina extending inward less than a half of the body width,
  • Vulva protruding,  at 54-60% of body length
  • Rectum 0.6-1.4 times abd.
  • Taiconical-elongate, narrower at the distal portion, with acute tip.

Ref: Yadav et al., 2023

Male:

  • Monorchic, testis reflexed on the dorsal side
  • Tail conical, distally curved ventrad.
  • Two pairs of precloacal genital papillae; five pairs of caudal genital papillae are present along the tail.
  •  Spicules curved ventrally: manubrium rounded, ventrally bent, calamus weakly developed, lamina ventrally curved,
  • Gubernaculum well developed, deltoid, about 30-49% of the spicule length
