Morphology and Anatomy:


Small plant-parasitic nematodes, 0.3 mm long. 


Swollen Females: 

  • 4 incisures in the lateral field,
  •  lip region conoid anteriorly flattened, without submedian lobes.
  • Vulval lips enlarged, protruding from the body contour,
  • Tail shorter than that in slender female; ends in a fine  point.
  • Spermatheca round, filled with sperm.
  • Gravid female may swell anterior to vulva.

Slender Females:

  • Stylet 56.2 (50–62) μm long,
  • Excretory pore at level of nerve ring;
  • Vulva a transverse slit with small advulval flap;
  • Ovary single, outstretched.   
  • Tail conoid gradually tapering to a fine .


Ref Maria et al., 2020


  • Devoid of stylet,
  • Esophagis rudimentary with inconspicuous structures
