Morphology and Anatomy:

 

   Males:

  • Similar to females except for reproductive system.
  • Monorchis, testis anteriorly outstretched
  •  Spicules paired and ventrally arcuate, rounded manubrium and a pointed distal tip.
  • Gubernaculum arcuate.
  • Bursa extends from the base of the spicules to mid tail.
