Morphology and Anatomy:

The species is characterized by:

.

 Refer to subfamily diagnosis (Tylenchinae).

Female:  

  • Monodelphic, prodelphic, ovary outstretched.
  • Vulva a small slit at 69.4-72.3% of body length.
  • Large spermatheca, length about 2.75 times corresponding body width, with large spheroid sperm.
  • Postvulval uterine sac (PUS) about as long as the vulval body diameter.
  • Females with delicate 5.7 to 6.9 um  stylets with small, slightly posteriorly sloping knobs, .
  • Tail is conoid and elongate, with a broadly rounded tip

 The  species closely resembles O. facultativus, but lacks incisures in the lateral field and is also separated  based on morphological and molecular data (Mahboubi et al., 2023).

Males:  

  • Common and functional.
  • Small bursa
  •  Tail is conoid and elongate, with a broadly rounded tip.
