Morphology and Anatomy:

.

Female:
  • Moderately slender (a=29-33), 2.16-2.46-mm long.
  • Cuticle was two-layered, 2 to 3-um thick at the anterior region, 3.5 to 4um in mid-body, and 6.5 to 8.5um on the tail;. 
  • Lateral chord occupying 21 to 27% of mid-body diameter.
  • Body pores obscure.
  • Lip region  truncate, offset by a distinct constriction, 1.9 to 2.3 times broader than high .21-26% of body diameter at the neck base;
  • Lips were withprotruding labial and cephalic papillae.
  • Amphid fovea  cup-like,, occupying up to one-third (28-33%) of lip-region diameter.
  • Cheilostom a truncate cone.
  • Odontostyle was relatively long and slender, about twice  the lip-region diameter,aperture 20-25% of odontostyle length.
  •  Odontophore  rod-like, nearly equal length of odontostyle. T
  • Pharynx conspicuously muscular, slender portion enlarging gradually, and the basal expansion occupying 47-52% of neck length;
  •  Pharyngo-intestinal junction a well-developed, conical cardiaenveloped by the intestinal wall.
  • Genital system was didelphic-amphidelphic, with both branches equally developed, anterior 10 to 13%, posterior  9 to 14% of the total body length. Ovaries reflexed; a narrowing surrounded by a muscular phincter between oviduct and the uterus.
  • Vagina extended inward, occupying 39 to 46% of body diameter: pars proximalis surrounded by moderately developed circular musculature; pars refringens consisting of two trapezoidal sclerotized pieces, pars distalis measured 4.5 to 6.5-um long.
  • Vulva a transverse slit. P
  •  The tail conical, gradually tapering to a finely rounded tip, and strongly curved ventrad, with abundant saccate- or blister-like bodies inside the cuticle in its anterior third;
  • Two pairs of caudal pores, one subventral, another subdorsal, at about one anal-body diameter behind hyaline terminal 22-28% of the total tail length.
