Abstract |
This work increases the number of issues dedicated to the studies about the Crustacean fauna of 'Main' quarry in Arzignano (Vicenza - N.Italy).The existence in the collections of the Museo Civico 'G.Zannato' of Montecchio Maggiore (Vicenza) of a great amount of not yet classified specimens, gathered during the past years, has allowed to identify some new species (Neocallichirus fortisi sp.nov., Eucalliax vicetina sp.nov., Eocalcinus cavus sp.nov., Kromtitis tetratuberculatus sp.nov., Calappilia subovata sp.nov., Daira salebrosa sp.nov., Montezumella pumicosa sp.nov., Eocharybdis cristata gen.nov., sp.nov., Eopilumnus checchii gen.nov., sp.nov., Eohalimede granosa sp.nov.) and to describe some well preserved specimens belonging to the already known species Petrochirus mezi (Lorenthey, 1909), Micromaia elegans Beschin, Busulini, De Angeli, Tessier, 1985 and Titanocarcinus aculeatus Busulini, Tessier, Visentin, 1984.Two new Heterotremata genera have been established, Eocharybdis gen.nov.(Portunidae Rafinesque, 1815) and Eopilumnus gen.nov.(Pilumnidae Samouelle, 1819).The findings of chelipeds belonging to the quite rare fossil Thalassinidea and Anomura are very interesting: the genera Neocallichirus Sakai, 1988 and Eucalliax Manning & Felder, 1991 had never been found in Italy before.The new species belonging to Kromtitis Muller, 1984 (K.tetratuberculatus sp.nov.) demonstrates once more the links existing with the Hungarian faunas of the same age.Daira salebrosa sp.nov.allows to improve the knowledge of Daira De Haan, 1833 : this genus probably originated in the Western Tethys and subsequently migrated to the Indo-Pacific.Eohalimede granosa sp.nov.confirms the links between the Eocene Crustacean fauna of Europe, namely of Venetia, and of North and Souh Carolina (U.S.A.).The sea where the crustaceans of 'Main' quarry lived had shallow water and a muddy or sandy bottom |
