Morphology and Anatomy:

 

Female:

  • Body almost straight.
  • Labial region with two annuli, 2 μm high × 7 μm widee, offset from body by a slight constriction.
  •  Stylet with ellipsoidal knobs.
  • DEGO 2- 2.5 μm posterior to stylet base.
  • Metacorpus oval, 11-13 μm high × 8.5-11 μm in diam.
  • Isthmus slender, encircled by nerve ring in upper part, located just posterior to metacorpus.
  • Pharyngeal gland lobe overlapping intestine ventrally.
  • Lateral fields with four incisures, not areolated.
  • Gonad 144-240 μm or 32-47% of body length; spermatheca small, rounded or oval,  filled with sperm; Post-uterine sac about 1.5 body diam. long.
  • Tail bluntly pointed  or subacute, with smooth terminus.

Male:

  • Body similar to female but slightly smaller.
  • Lip region slightly offset, 2 μm high and 5.7 μm broad, with two annuli (second annulus higher than first).
  • Stylet more slender and shorter than in female, with minute, slightly cupped knobs.
  •  Hemizonid just anterior to secretory-excretory pore, hemizonion eight annuli posterior to it.
  • Lateral field with four smooth lines.
  • Testis outstretched, 238 μm long.
  • Tail conoid, with narrowed hyaline tip, 4 μm long.
  • Spicules arcuate, weakly cephalated, gubernaculum simple, slightly arcuate.
