The bicosoecids, formally Bicosoecida (ICZN) or Bicosoecales/Bicoecea (ICBN), are a small group of unicellular flagellates, included among the heterokonts. The cells are free-living, with no chloroplasts, and in some genera are encased in a lorica. The name of the type genus ''Bicosoeca'' described by James-Clark in 1867 is derived from Greek roots (''bikos'', vase, bowl, plus ''oekein'', inhabit). The philologically preferable compound would be ''Bicoeca'', as "corrected" by Stein in 1878 and followed by most subsequent authors. However, according to the ICBN and ICZN, the original spelling of the name cannot be considered incorrect and it must be used in its original form. The group was formerly considered to be related to the Chrysophyceae.〔David J. Hibberd (1978) (''Bicosoeca accreta'' sp. nov., a flagellate accumulating extraneous silica fragments ), ''British Phycological Journal'', 13:2, 161-166.〕 Some authors use the vernacular term "bicosoecid" (or "bicoecid") in a narrower sense, only for ''Bicosoeca'', aplying "bicoeceans" to ''Bicosoeca'' and related groups like ''Cafeteria''.〔 Supplementary material ().〕 ==External links== * 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「Bicosoecid」の詳細全文を読む スポンサード リンク
