abstract = "The paper describes a new genus and new species of Cyanoprokaryota, referred to Pleurocapsales incertae sedis – Cyanocystopsis kitagatae gen. et sp. nov. The new taxon is characterized by the presence of two different stages (filamentous, formed by spherical cells and stalked bundles of claviform cells). The branching of filaments, which leads to the formation of clusters of claviform cells, is caused by cell division, which slightly resembles the true-branching of cyanoprokaryotes. However, this division is peculiar by its subsequent character and excentric disposition of the daughter cells, which leads to the formation of specific tetrads, from which the claviform cells develop. Spores (aplanospores) and vegetative reproductive stages of the alga have been observed. The new species was found as a dominant in a fixed phytoplankton sample from the small, hypertrophic and hypersaline tropical crater lake Kitagata (Uganda, Africa). The pigment marker analysis of the same sample proved the high (ca 96%) cyanoprokaryote contribution to the phytoplankton biomass.",

note = "Funding Information: Water samples were collected by C{\'e}dric Morana, Marc-Vincent Commarieu and Alberto Borges (University of Li{\`e}ge) in the frame of the HIPE project, funded by the Belgian Science Policy Office (BELSPO, Brussels, Belgium) under the BRAIN program (BR/154/A1/HIPE). Funding Information: The material was collected on 8.04.2017 from the small tropical crater lake Kitagata (Uganda, Africa). The lake was sampled once during the HIPE project, supported by the Belgian Science Policy Office (BELSPO, contract # BR/154/A1/HIPE), but it had been studied before by Russell et al. (2007) for climate reconstruction in Africa and by Ma et al. (2011) for its peculiar geochemical features, involving brine formation. According to Ma et al. (2011), lake Kitagata is a small (0.62 km2), perennial saline lake located in the western branch of the East African Rift System, southwestern Uganda, lying within a 1.8 km2 steep-walled crater (Fig. 1).
