Morphology and Anatomy:

.

Female:

  • Didelphic-amphidelphic. Ovaries moderately developed with oocytes first in two or more rows, then in only one row.
  • Oviduct 1.1-1.5 times body diameter long, consisting of a slender distal region of prismatic cells and a well-developed
    proximal pars dilatata with lumen inside.
  • Sphincter between oviduct and tripartite, convoluted uterus.
  • Vagina extending inwards 38-44% of body diameter: pars proximalis with almost straight walls surrounded by weakly developed musculature, pars refringens of two adjacent trapezoidal, sclerotized pieces , and pars distalis 3-4 um long.
  • Vulva slightly postequatorial, a transverse slit.
  • Caudal pores one pair, at the middle of tail, one subdorsal, another lateral.

 

 

 

 

 

 

 

 

 

Males:  
  • Genital system diorchic,Diorchic, testes opposed.
  • An ad-cloacal pair of supplements and a series of 14-18, almost contiguous  ventromedian supplements
  •  Spicules dorylaimid, 4.9-5.5 times as long as wide, 1.5-1.8 times the body
    diameter at level of the cloacal aperture
    Lateral guiding piece 13-14 um long, tapering in its posterior third.
  • Caudal region basically similar but either straighter or slightly curved ventrad at the end.
