This paper deals with the systematic study of eleven taxa of the genus Staurastrum belonging to the complex Staurastrum levanderi. Cluster analysis was performed on morphological and biogeographical data from 19 characters. The results of this study lead us to differentiate ten species and one variety. Among these taxa we propose four new names (three species and one variety): S. iberaense nom. nov. and stat. nov., S. pseudochaetopus nom. nov. and stat. nov., S. tracannae spec. nov. and S. levanderi var. capdeviellei var. nov.
