Morphology and Anatomy:

• Small nematodes, slightly or tightly coiled:

• Buccal capsule vestigial, annular. Mouth opening triangular with rudimentary lips; labial and cephalic papillae not
  observed.

• Esophagus claviform. Nerve ring in region of anterior half of esophagus,

• Deirids and excretory pore in posterior third of esophagus

• Synlophe with 20-30 ridges in both sexes. Ridges continuous. Careen absent. Ridges markedly unequal in size. Left ridge distinct from ridge 1'. Mid-left and mid-right ridges largest.
