Ecdysozoa subclasses

The Enoplia are a subclass of nematodes in the class Enoplea.

Subclass Rhabditia is mostly composed of parasitic nematodes (particularly in the Strongylida), though there are some free-living species as well (particularly in the Rhabditida). Phasmids (posterior sensory structures) are well-developed, while amphids (anterior sensory structures) are poorly developed or absent in this group.

Dorylaimia is a subclass of nematodes.
