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 genusBicosoeca 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.
