The Enoplia are a subclass of in the class Enoplea.
Description
Enoplians are characterized by
shaped like ovals,
, or pouches. Their bodies are smooth, without rings or lines. The
esophagus is cylindrical and glandular.

Taxonomy
Lorenzen described two orders, Enoplida and Trefusiida, in the 1980s based on morphology. With the advent of phylogenetic analysis, a reorganisation has been necessary, moving the Triplonchida here to create three orders and expanding it.
[ Phylum Nematoda. Nematode Classification. Department of Nematology. University of California, Riverside.]
The orders are distinguished mainly by habitat type.
Phylogeny
Enoplia is regarded as the earliest nematode branch, according to recent phylogenetic analysis.
