Class Adenophorea Adenophorea, also known as Aphasmidia because of the lack of phasmids on their tails, are usually found in the water. They have simple excretory and digestive systems. This class of nematodes is considered to be less advanced, or less evolved, than the Secernentea. The males usually have two testicles.

Adenophorea Chitwood, 1958 is a paraphyletic group (classis or subclassis) of Nematoda. This taxon included two subordinate taxa: Enoplia and Chromadoria. The name Adenophorea is rarely used in modern literature, because this group is broken up to accommodate phylogeny: Enoplia is classified now as classis Enoplea.
