  • Amphid apertures oval

  • Six labial papillae, six 0uter labial setae horn-like (cornuate), four smaller cephalic setae.

  • Odontostyle needle-like, odontophore with flanges.

  • Esophagus terminating in pyriform bulb

  • Tails of both sexes conical

Female:

  • Monodelphic, opisthodelphic
  • Vulva a transverse slit
