Genus Charybdis De Haan, 1833

Portunus (Charybdis) De Haan, 1833: 10 , type species by subsequent designation ( Glaessner 1929: 113): Cancer sexdentatus Herbst, 1783: 153 , pl. 7 fig. 52 [ Cancer sexdentatus Herbst, 1783 became an objective junior synonym of Cancer feriatus Linnaeus, 1758 by the designation of the same specimen as lectotype for the two taxa by Holthuis (1962: 234–235)].

Charybdis .— Alcock, 1899: 47 [precedence given over Oceanus, in application of the Principle of First Reviser ( ICZN 1999)]; ICZN 1964: 337 (placed on official list of names in zoology).

Portunus (Oceanus) De Haan, 1833: 9 , type species by monotypy: Portunus crucifer Fabricius, 1798 [= Charybdis feriata (Linnaeus, 1758) ], name preoccupied by Oceanus de Montfort, 1808 [Mollusca].

Goniosoma A. Milne Edwards, 1860: 263, type speecies not specified, name preoccupied by Goniosoma Perty, 1833 [Arachnida].

non Charybdis Cocco, 1832: 207 ; type species Charybdis Zanclea Cocco, 1832 [Amphipoda], placed on the Official Index of Rejected and Invalid Generic names in Zoology by ICZN (1964: 342).

The recent phylogenetic analysis of Portunoidea by Evans (2018) recovered a monophyletic Charybdis lineage

(excluding Goniosupradens Leene, 1938 ) with strong support, but there was no support for other proposed

Charybdis subgenera. Therefore, we no longer use subgenera for Charybdis hellerii and its synonyms.
