Abstract

Study is part of the taxonomic survey of the São Paulo State Algalflora and integrates FAPESP's Thematic Project "Flora Ficológica do Estado de São Paulo". Identification, description and cataloging of the pigment and colorless members of Division Euglenophyta will be made by analyzing the sample units deposited at the Instituto de Botânica Herbarium "Maria Eneyda P. Kauffmann Fidalgo "(SP) and all material previously published that includes the possibility of re-identification. New collections will be made whenever more material or living material will be needed to complement the taxonomy. Study of São Paulo State euglenoid flagellates began in the late 60s, through nine papers written by Boris Vassilievich Skvortzov. Followed eight works published in the 80s and 90s, prepared by Míriam Borges Xavier. Recently, four papers about colorless euglenoids were published by Carlos Eduardo de Mattos Bicudo. However, most of those studies refer to samples collected at the Parque Estadual das Fontes do Ipiranga, thus reflecting the great need for a flora that will include material from all over São Paulo State. Despite of the euglenoids have a worldwide wide geographic distribution and have already been widely studied, their taxonomy is still a matter for much discussion. In the last two decades, papers were published using molecular biology techniques to elucidate taxonomic and phylogenetic questions in the group. However, most of these studies failed to solve, in practice, the taxonomic questions originated by them, leaving a large gap to be filled by flora works that shall revise former identifications as to include the genera and species new nomenclature. In this context, the objective of this research will be to identify the pigmented and colorless Euglenophyta occurring in the São Paulo State using the criteria proposed by the classic morphological studies, however, updating them in accordance to the propositions in the recent phylogenetic studies.
