The Chromadorea are a class of the roundworm phylum, Nematoda. They contain a single subclass (Chromadoria) and several orders. With such a redundant arrangement, the Chromadoria are liable to be divided if the orders are found to form several clades, or abandoned if they are found to constitute a single radiation.

Apr 9, 2019 · Chromadoridae is a widespread family of mostly free-living marine nematodes. This systematic review provides for each genus: a historical background, an updated diagnosis and a list of species.

The lateral side of the nematode body is mostly characterized by the presence of lateral lines or incisures (Chromadorea) (Fig. 3.2B), the number of which is also of some taxonomic importance for lateral hypodermal glands (for some Enoplia).
