Abstract

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 Glaes ner, 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.
