Morphology and Anatomy:

Large to very large nematodes but slender, 5 to 12 mm long.

.
  • Labial region expanded and offset from the bodu contour.
  • Odontostyle is long and slender
  • Stylet extension (odontophore) not flanged.  
  • Guiding ring near anterior of odontostyle
  • Opening of amphids wide and slit-like .
  • 10-17 ventromedian supplements.with the most posterior being within one spicule length of the cloaca
  • Tail short, bluntly rounded
  • Among the longest plant-parasitic nematodes.
  • Morphologically close to Paralongidorus and considered by some authorities to be part of the same genus. Differs primarily with the offset head region rather than a conrtionuous contour..
