Eremosphaera tanganyikae sp. nov. (Trebouxiophyceae), a new species from lake Tanganyika
Abstract:Representatives of the Trebouxiophyceae genus Eremosphaera (with the exception of E. viridis) show great variation in their morphology, and some of the described species, varieties and forms are still of uncertain taxonomic position. Recent material from the phytoplankton of the large, deep, alkaline, ancient, tropical Lake Tanganyika was compared with the formerly described taxa and was found to be peculiar by the ellipsoidal cells with lamellate cell walls, commonly equipped with polar nodules consisting of two parts, by the numerous (30-60) parietal wedge-shaped chloroplasts densely pressed to each other and arranged in (2)-3-4 circles (each chloroplast bearing 1-2 distinct pyrenoids covered by bipartite starch sheath), as well by its ecological requirements. Therefore, a new species, E. tanganyikae sp. nov., is erected.
