New reports of anomurans and brachyurans from the Cenozoic of Tuscany (Italy)

Abstract

Anomurans and brachyurans from Tuscany have previously been reported by Cappellini (1874), Fucini (1910), Ristori (1886, 1888, 1891, 1892, 1896), Vinassa de Regny (1897), and Delle Cave (1988a, b). The recent discovery of new anomurans and brachyurans from some localities in Pisa, Livorno, Siena, and Grosseto provinces increases the carcinologic knowledge from the Cenozoic of Italy. The infraorder Anomura H. Milne Edwards, 1832, includes Callianassa cfr. C. subterranea (Montagu, 1808) and C. chalmasii Brocchi, 1882 (Callianassidae Dana, 1852); Dardanus substriatus (A. Milne Edwards, 1861) (Diogenidae Ortmann, 1892). The infraorder Brachyura Latreille, 1802, includes Lysirude paronae (Crema, 1895) and Raninoides pliocenicus n. sp. (Raninidae De Haan, 1839); Medorippe ampla Garassino, De Angeli, Gallo & Pasini, 2004 (Dorippidae MacLeay, 1838); Ethusa popognensis n. sp. (Ethusidae Guinot, 1977); Calappa granulate (Linnaeus, 1758) (Calappidae H. Milne Edwards, 1837); Ebalia cfr. E. deshayesi Lucas, 1846, E. cranchii Leach, 1817, E. fucinii Ristori, 1892, Ilia pliocenica Ristori, 1891, and Palaeomyra bispinosa A. Milne Edwards, 1861 (Leucosiidae Samouelle, 1819); Liocarcinus sp. (Poriunidae Rafinesque, 1815); Monodaeus bortolottii Delle Cave, 1988 (Xanthidae MacLeay, 1838); Pilumnus ristorii new replacement name for P spinosus Ristori, 1886 (Pilumnidae Samouelle, 1819); Eriphia cocchii Ristori, 1886 (Eriphiidae MacLeay, 1838); Goneplax gulderi Bachmayer, 1953 (Goneplacidae MacLeay, 1838); Astenognathus sp. (Varunidae H. Milne Edwards, 1853). The discovery of Raninoides H. Milne Edwards, 1837, is very important because it represents the first report of this genus in the Pliocene of Europe.
