Female Rhabditis, copyright Ken Ramos.

Belongs within: Rhabditina.

The Rhabditoidea is an assemblage of free-living nematodes, though it is probably paraphyletic to parasitic groups such as the Strongyloidea. Members of the Rhabditoidea are characterised by having the phasmid in males posterior to all other bursal rays (Ley & Blaxter 2002). The bacteriovorous Caenorhabditis elegans has become a model organism in the study of embryology.
