  • Lateral fields with 6 incisures.
  • Deirids present near level of excretory pore.
  •  Lip region low, flattened, smooth.
  • Stylet small, with conus less than half its length and small rounded basal knobs.
  • Median esophageal bulb oval, valvate.
  • Cardia absent.
  • Esophageal glands extending over intestine mostly laterally; dorsal gland enormously developed.
  • Tail in both sexes elongate-conoid to filiform.
