Female:

  • Cuticle with transverse and longitudinal striae forming small square marks.
  •  Lip region continuous with body contour.
  •  Lips rounded with thin setae.
  • Stoma rhabditoid. Cheilostom wide, gymnostom slightly wider than long, stegostom cylindrical; metastegostom bearing glottoid apparatus with minute teeth.
  • Esophangeal corpus with procorpus cylindrical and metacorpus swollen; procorpus 1.5 times longer than metacorpus.
  • Isthmus wide, tapering gradually from metacorpus to junction with basal bulb.
  • Basal bulb ovoid, with valves at its midpoint.
