  • Lip region strongly offset from body contour; lips separate..
  • Odontostyle sinuate, about 2x labial diameter, thinner than cuticle..
  • Esophagus widening gradually
  • Female genital system diovarial, amphidelphic; vulva longitudinal.

  • Spicules dorylaimoid
  • Tail in both sexes short and bluntly rounded, with offset recurved tip in females and juveniles.
