Summary During an investigation of the silica-scaled chrysophytes in Tierra del Fuego, eighteen taxa were found, which had not previously been recorded from Argentina. These give a new insight in the biogeographical distribution of these algae. Three groups of species could be distinguished; one shows a pattern of latitudinal distribution in temperate areas of the Northern and Southern Hemisphere, the other has a general distribution in temperate, subtropical and tropical regions. The third group contains a few endemic species. |
