Morphology and Anatomy:

.
  • Slender nematodes without sexual dimorphism.
  • Fine cuticular striation.
  • Head offset and narrower than body.
  • Stylet short, 7-10 µm with small, rounded knobs.
  • Esophageal bulb not muscular and with small valve.
  • Dorsal esophageal glands abutting to slightly overlapping intestine; subventral glands overlapping intestine ventrally.
  • Excretory pore anterior, at level of stylet knobs.
  • Female gonad monovarial, prodelphic with postuterine sac.
  • Male with slender spicules, simple gubernaculum and bursa extending from about 1 cloacal body diameter anterior to cloaca to a similar distance posterior.
  • Tail conoid with short pointed terminus.
