摘要

Mixtacandona talianae n. Sp. (Ostracoda, Candoninae), collected in the Holocene filling sedimentary succession of the Grotta del Lago near Triponzo (Umbria, Central Italy), is described and illustred. This medium-small sized species is characterized by a Remarkable dorsal protuberance on the left valve. ~14C radiometric ages on the sediments correlatable with those bearing the new species Have provided ages of 4, 527-4, 409 y BP (calibrated ages).
