Partially resolved phylogeny of clades within the order Rhabditida, derived from small subunit rDNA* sequence analysis

Order Rhabditida in our system corresponds largely with Class Secernentea or Rhabditea in previous systems; taxa were Cephalobomorpha and Panagrolaimomorpha

*SSU rDNA is also frequently referred to as 18S or 16S rDNA
