Received: Accepted: JPublished: MaShow citation Keywords: carotenoids, ecology, Guatemala, Lake Atitlán, Limnoraphis, planktic Lyngbya, taxonomy, ultrastructure, water-blooms Based upon molecular, morphological and ecological data, a new genus Limnoraphis was proposed with four species. The main diacritical markers of this clade were the planktic type of life and formation of gas vesicles in cells. robusta, together with few other planktic species, formed a clade, separated from typical Lyngbya species. Molecular phylogenetic analyses using the 16S rRNA gene showed that L. It contained a high amount of carotenoids, which caused an unusual brown color of the macroscopic scum on the water level. It produced aerotopes that were irregularly spaced in cells cyanotoxins were not found, and it fixed nitrogen in spite of the lack of heterocytes.

This species had several unique features. robusta using 16S rRNA gene sequencing, cytomorphological markers, and ecological characteristics was made. This was one from the first known cases of L.
