* †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]
