This study aimed to perform thetaxonomic survey of the species of periphytic Cyanobacteria in a lentictropical environment, seeking to contribute to the knowledge on biodiversityand their distribution. This study was conducted at the SamambaiaReservoir, which is located at Federal University of Goiás, Goiania, CentralWest region of Brazil. In general, the water of the Samambaia Reservoir ischaracterized as more turbid and the increased biochemical oxygen demand aswell as a higher concentration of coliforms in the rainy season. Twenty sixsamples were collected, ten in the dry season 09-2010 and 11-2010; 07-2012and ten in the rainy season 01-2011 and 03-2011; 01-2013. Periphyton wascollected from stems of aquatic plants Cyperaceae, which were in the marginalarea of the reservoir. With the floristic survey, 38 taxa of Cyanobacteria wereidentified in periphyton of the Samambaia Reservoir. Phormidium familyPhormidiaceae and Aphanocapsa Merismopediaceae are among genera with thehighest species richness. Regarding morphological types, many species offilamentous cyanobacteria were identified, followed by colonial taxa. Inrelation to the frequency of occurrence and the seasonal period, 14 taxa wereclassified in the rare category, 12 in common category and 12 in constantcategory. Regarding the seasonal period, Cyanophyceae were the greatest wealthin the rainy season 97.4%.
