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.〔ToL (2002)〕 Characteristics supposed to distinguish Adenophorea are: * amphids always post-labial, variable 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. == Footnotes == 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Adenophorea」の詳細全文を読む スポンサード リンク
