Morphology and Anatomy:

.


Fungiotonchium is distinguished from Iotonchium by presence vs absence of a vulval flap in the free-living entomoparasitic female and with cylindroid spicules with an extremely slender extension that ends in a spine or notch in the male.

Ref: Siddiqi, 2000. 

Female:  

  • Insect-parasitic and free-living forma
  • Monodelphic, prodelphic, no postvulval uterine sac
  • Vulval flap present
  • Tail elongate conoid to filiform
 

Males:  

  • Stylet degenerate
  • Cylindroid spicules with an extremely slender extension that ends in a spine or notch
  • Bursa envelopes tail.
  • Esophagus degenerate or absent
