Morphology and Anatomy:

• Body length 1.8–2.3 mm, maximum body diameter 55-59 um
• Cuticle smooth.
• Six very small labial papillae. Four cephalic setae, 0.6-1.0 h.d. long.
• Somatic setae in submedial rows in the preneural region of the body. Four groups of submedial cervical setae, three setae in females and two setae in males in each group at the level of the base of the stoma.
• Amphideal fovea elongated loop, 1.5 h.d. long, located between cephalic setae and stoma base.
• Buccal cavity double-conical, 2.0 h.d. deep. Stomatoidal ring simple, surrounds the buccal cavity between its anterior and posterior conical sections.
• Excretory pore opening about one stoma length behind base.
• Tail long, 189-233 um, conical becominc cylindrical near end. About 20 pairs of genital setae on its ventral surface; four submedial setae near tail tip.
