N2 - This study presents the first record of a living dinoflagellate cyst with a hypocystal, antapical archeopyle. It is also the firstdetailed account of the archeopyle of a living freshwater cyst from the genus Peridinium. The cysts were isolated from sedimenttraps deployed in Lake Nero di Cornisello, a low-alkalinity high mountain lake of the Adamello mountain range (2233mabove sea level, South Eastern Alps, Italy). The archeopyle is large, clearly hypocystal, polygonal, and slightly peanut-shaped.The species producing this cyst belongs to the Peridinium umbonatum group and is described based on scanning electronmicroscopy and light microscopy. Partial sequences of SSU rDNA were obtained and compared with previously publishedsequences from the P. umbonatum group. The taxonomic position of the species is discussed.
