Taxonomy and nomenclature

Species concepts in Cafeteria are based primarily on external morphology; only the type species, C. roenbergensis, has been extensively characterized at the ultrastructural and molecular levels.

"Bicosoecids" vs. "bicoecids":

The genus that lends its name to this protist group was described in the last quarter of the 19th century. The name was spelled, in different places and by different authors, Bicosoeca, Bicoeca or Bikoeca. Botanically-trained systematists generally have used Bicosoeca (and "bicosoecids", Bicosoecaceae, etc.), while zoologically-trained systematists generally have used Bicoeca (and its derivatives). However, the eldest (first published) name is Bicosoeca, and therefore, according to the rules of nomenclature ("principle of priority"), it is the correct name for both botanists and zoologists.
