Fabricius, 1775

Exopod of third and first maxilliped without a flagellum; the flagellum of the second maxilliped transformed into a single laminate segment. Orbits on the anterior margin of the carapace, some distance from the anterolateral angle. Body not depressed, but rather high and vaulted. Lateral margin of the carapace with both cervical and postcervical incisions, neither of which is very deep. Lateral margin of the carapace with numerous teeth or squamiform tubercles.

Type Species: by monotypy: Cancer arctus Linnaeus, 1758.

More than 40 species are known in this genus, they are listed below. Most species are small and of no economic value. A few (only 7 are known to me) have been reported from fish markets, but even those can only be considered as accidental bycatch of other species. Hence, a key to species is not presented here, but, short diagnoses are provided for the 7 species reported from fish markets as an aid for their recognition.
