'''Enoplida''' is an [order](/source/order_(biology)) of [nematode](/source/nematode)s. It is one of two orders in [Enoplia](/source/Enoplia), which is one of two subclasses in Class [Enoplea](/source/Enoplea).<ref name=ucd>[http://plpnemweb.ucdavis.edu/nemaplex/Taxadata/Enoplea.HTM Class Enoplea.] {{Webarchive|url=https://web.archive.org/web/20130928180359/http://plpnemweb.ucdavis.edu/nemaplex/Taxadata/Enoplea.HTM |date=2013-09-28 }} Nemaplex: Nematode-Plant Expert Information System.

== Subdivisions ==
Upon [phylogenetic analysis](/source/Molecular_phylogenetics) in 2010, the order was divided into five [clade](/source/clade)s. Clades and selected [families](/source/Family_(taxonomy)) include:<ref name=bik/>
