Abstract
During a survey of the chrysophycean stomatocyst flora in some small pools on top of the Monte Lauro, the culminating point of the Hyblean Mountains in southwestern Sicily (Italy), a total of 38 morphotypes, including 11 new, has been observed. Thirty-two morphotypes are described herein based on scanning electron microscopy observations with an additional six morphotypes, only observed by light microscopy. These records improve our knowledge on the cyst flora in the Mediterranean region.
