Morphology and Anatomy:

  • Body annuli are wide (13-17um at mid-body) with fine longitudinal striations with rough cuticular margins; 2 to 3 anastomoses in posterior half of the body.
  • The first cephalic annulus is rounded and expands to enclose the lip region; the second annulus narrow, offset, collar like.
  • Central elevated labial disk with four equal-sized submedian lobes and �I�-shaped oral aperture.
  • Stylet robust with anchor-shaped basal knobs, and DGO indistinct.
  • Esophageal lumen is looped in median esophageal bulb which has a medium-sized valvular apparatus.
  •  Isthmus narrow, short, encircled by nerve ring.
  • Basal esophageal bulb distinct.
  • Excretory pore is 3 to 4 annuli posterior to esophageal bulb.
  • Anus located on the next annuli posterior to vulva.
  • Tail is short and conoid, longitudinal striations are more prominent on the terminal annulus that gives the appearance of forked or branched terminus.

Female:

  • Monodelphic gonad is outstretched, and spermatheca is spherical, filled with sperm.
  • Vagina is straight, vulva is closed, and vulval lips do not project above body contour.

Male:

  • Not seen but assumed to exist based on presence of sperm in spermatheca.
