This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
The floristic survey of Brachysira Kützing (Naviculales) of the Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, São Paulo State, Brazil, resulted from the analysis of 31 permanent preparations of diatom material collected between years 1991 and 2017. The water and substrate samples (macrophytes and rocks) from lentic systems, streams and the hydrophytoterium were collected and subsequently were oxidized for analysis under light microscope. Nine species and one morphotype were identified from 15 diatom slides, of which four species are new records for Brazil (Brachysira cf. calcicola Lange-Bertalot, Brachysira frenguellii (Manguin) Lange-Bertalot & Moser, Brachysira huitotarum Vouilloud, Sala & Núñez-Avellaneda and Brachysira intermedia (Østrup) Lange-Bertalot). Brachysira subrostrata Lange-Bertalot was registered for the first time in the State of São Paulo
RESUMO
O levantamento florístico do gênero Brachysira Kützing (Naviculales) do Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, SP, Brasil, resultou da análise de 31 preparações permanentes de material coletado entre 1991 e 2017. As amostras de água e de substratos (macrófitas e rochas) de sistemas lênticos, riachos e do hidrofitotério foram coletadas e posteriormente oxidadas para análise ao microscópio de luz. Nove espécies e um morfotipo foram encontrados em 15 amostras de material do PEFI, sendo quatro novas citações para o Brasil (Brachysira cf. calcicola Lange-Bertalot, Brachysira frenguellii (Manguin) Lange-Bertalot & Moser, Brachysira huitotarum Vouilloud, Sala & Núñez-Avellaneda e Brachysira intermedia (Østrup) Lange-Bertalot). Brachysira subrostrata Lange-Bertalot foi registrada pela primeira vez no Estado de São Paulo.
