Cymbella gravida sp. nov. A new lacustrine taxon from Santa Cruz, Argentina

This study presents a detailed morphological analysis using light and scanning electron microscopy of Cymbella gravida sp. nov. collected from the deep sediments of Laguna Potrok Aike, a maar lake in the province of Santa Cruz, Argentina. An attempt was made to describe its ecological preferences ba...
