Morphology and Anatomy:

• Cuticle coarsely striated in neck region, otherwise smooth.
• Head high and rounded.
• Stylet short with very small knobs.
• Median bulb with valve.
• Females monodelphic, prodelphic with short postvulval sac; vulva at 70-73%
• Males with cephalated spicules, trough-shaped gubercancilum  and adcloacal caudal alae.
• Tail tip rounded.

Note: Andrassy (2007) questioned the validity of the genus and, based on the non-filifom tail and very small stylet knods, suggested that it was clos to Thada Thorne, 1941 or Neothada Khan, 1973. Geraert (2008) points out that it also resembles Polenchus.
