Resumo: Fragilaria longifusiformis (Hains & Sebring) Siver et al. is a planktonic diatom distributed widely aroud the world, with rare published records or information on its occurrence in Brazil. We believe that the valve face ornamentations, inconspicuous under light microscopy, hinder the accurate identification of the species, leading to misidentification with other similar species of Fragilaria Lyngbye , Synedra Ehrenberg or Nitzschia Hassall. The goals of this study were to illustrate the morphological variability of the southern Brazilian specimens, with and without plastids, detail the ultrastructure of the taxon and confirm the geographic distribution of populations in regional reservoirs and rivers. Phytoplankton sampling was carried out from 2007 to 2011. The morphological characteristics of Brazilian populations of F. longifusiformis matchthe original circumscription of this species, except for smaller valve dimensions of somespecimens.

Acredita-se que as ornamentações da face valvar, inconspícuas sob microscopia óptica, comprometem a identificação acurada da espécie, causando inclusive, confusão com outras espécies semelhantes de Fragilaria Lyngbye e Synedra Ehrenberg, ou ainda, com Nitzschia Hassall. Os objetivos do estudo foram ilustrar a variabilidade morfológica de espécimes sulbrasileiros com e sem plastídeo, detalhar a ultraestrutura do táxon e confirmar a distribuição geográfica das populações em reservatórios e rios da região. Amostragens de fitoplâncton foram realizadas nos anos de 2007 a 2011. As características morfológicas das populações brasileiras de F. longifusiformis foram condizentes com a circunscrição da espécie, exceto por alguns exemplares com menores dimensões valvares.Iheringia.
