This study aimed to inventory the species of the genus Pinnularia present in pristine streams located in the cerrado biome (Midwest Brazil) between the years 2012 and 2013. The periphyton was collected in five streams in the savannah, in different substrates and seasons. Were identified 23 species, of which 17 are on the 1st occurrence of citations for the Midwest Region: P. angustivalva, P. butantanum, P. castraregina, P. divergens var. biconstricta, P. divergens var. mesoleptiformis, P. divergens var. protracta, P. gibba var. subundulata, P. meridiana var. meridiana, P. microstrauron var. rostrata, P. paulensis, P. persudetica var. persudetica, P. subgibba var. angustarea, P. subgibba var. capitada, P. superpaulensis, P. viridiformis var. minor and P. undula var. undula. Taxa that had a higher frequency of occurrence in the studied streams were P. subanglica, P. angustivalva, P. brauniana and P. butantanum.application/pdfAcesso AbertoDiatomáceasPerifítonCórregosDiatomPeriphytonStreamsCIENCIAS BIOLOGICAS::BOTANICADissertação
