The following species are known:[3]

  • C. elkneri Gorisdro-Kulczycka, 1950 - Late Devonian (Frasnian) of Poland
  • C. excessus Krupina, 1990 - Late Devonian (Famennian) of Oryol, Russia
  • C. jerofejewi (Pander, 1858) - Late Devonian of Leningrad, Russia (=Cheirodus lateralis von Eichwald, 1846)[4]
  • C. ostreaformis McCoy, 1848 (type species) - Devonian of Scotland
  • C. parvulus Bryant ex Bryant & Johnson, 1936 - Famennian of Colorado, USA[5]
  • C. pinguiculus Krupina, 1990 - Devonian of Russia
  • C. variabilis Eastman, 1908 - Late Devonian of Iowa and Missouri, USA

An indeterminate species is known from Latvia.[6] The species C. plicatus Dawson, 1868 of Nova Scotia is now placed in Sagenodus as S. plicatus.[7]
