Adenophorea
Adenophorea or Aphasmidia was a class of nematodes (roundworms). It has been by and large abandoned by modern taxonomy, because there is strong evidence for it being a motley paraphyletic group of unrelated lineages of roundworms.

Characteristics supposed to distinguish Adenophorea are:
* amphids always post-labial, shape, pore-like to elaborate
* deirids are not seen
* phasmids are generally absent
* hypodermal glands present (excretory?) uninucleate
* simple non-tubular excretory system when present
* three caudal glands commonly opening through a spinneret at the tail tip
* male generally has two testes
* caudal alae are rare
* male with supplement glands in a single ventro-median row
* sensory papillae in cephalic region and along the body
* generally there are five esophageal glands
* marine, freshwater, terrestrial

As it seems, a number of these traits are plesiomorphic, and thus unsuitable to discern relationships.
