Revision of the fossil species of Goneplax Leach, 1814 (Crustacea, Decapoda, Brachyura, Goneplacidae)

Resumen

A revision of the
fossil species of Goneplax Leach, 1814, has resulted in the
assignment of four fossil species to Goneplax, but only G. gulderi
Bachmayer, 1953, and G. rhomboides are considered as valid. Goneplax
craverii Crema, 1895, previously assigned to Retropluma Gill, 1894,
G. formosa Ristori, 1886, and G. meneghinii Ristori, 1886, are
regarded as junior synonyms of G. rhomboides, while G. sacci Crema,
1895, is considered a nomen dubium. Albaidaplax n. gen. is here
erected to include both the Italian specimens from the Miocene of
Rio Popogna (Livorno, Tuscany, Italy) and the Spanish specimens from
the Pliocene of Guadalquivir Basin (Seville, Andalusia, Spain)
previously assigned to G. gulderi. Finally, Ommatocarcinus arenicola
Glaessner, 1960, from the Late Oligocene-Middle Miocene of New
Zealand, is assigned to the extant Neogoneplax Castro, 2007,
constituting the first report of this genus in the fossil
record.
