Morphology and Anatomy:

Morphologically, Oriverutoides is a well-characterized genus, distinguishable by a peculiar combination of features: lobe-like lips, odontostyle relatively long and slender with short aperture, pharyngo-intestinal junction often bearing three cardiac cells, and tail conically elongated usually with more or less (but always perceptible) bent dorsad end.

  • Medium length, 1.2-1.5 mm.
  • Cuticle finely striated
  • Lip region almost contiguous with body contour
  • Lips amalgamated with protruding papillae.
  • Odontostyle very thin
  • Odontophore simple
  • Esophagus dorylaimoid, gradually expanding to cylindrus; dorsal esophageal nuclus far posterior to esophageal expansion
  • Tail elongate-conoid, bent dorsally..

Female:

  • Monodelphic-opisthodelphic,
  • Vulva transverse

Male:

  • Male unknown for type species
