Morphology and Anatomy:

.

Female:

  • Didelphic-amphidelphic. Ovaries equally developed often, reaching and surpassing the sphincter level between oviduct and uterus.
  • Uterus tripartite, usually convoluted,
  • Vulva a post-equatorial, transverse slit,  surrounded by several circular, concentric striations. Often small holes, in cuticle on both sides of vulva.
  •  Anus a short transverse slit, ca 5 um long.
  • Caudal region conical with finely rounded terminus inner core with a distinct concavity, providing a digitate appearance; tail; inner core reaching 56-75% of tail length, followed by a hyaline portion

 

 

 

 

 

 

 

 

 

Males:  
  • Very rare, but apparently functional.
  • Diorchic, with testes opposed.
  • An adcloacal pait followd by  17, almost contiguous, 7-11 μm apart, ventromedian supplements.
  • Spicules dorylaimid, 1.9 times cloacal
  •  Lateral guiding piece  four times as long as wide.
  • Prerectum 2.9, cloaca 1.7 body diam. long.
  • Caudal region short, rounded conoid, ventrally without concavity,
