          Abstract

          ABSTRACT The species originally described from brackish waters of the Venetian Lagoon as Nitzschia persuadens is a diatom rarely cited in the literature since its proposition and it is here recorded for the first time in a freshwater environment in South America. Morphological features of this species, such valve slightly panduriform, with a longitudinal straight fold of the valve face, poroidal areolae, and strongly eccentric raphe system clearly assign this species to Tryblionella, and the transfer was made. Here we present new observations on the frustule morphology and comparisons with related species. Light and scanning electron microscopy data of Tryblionella persuadens comb. nov. from Cachoeira River, Northeastern Brazil are documented.

          RESUMO Nitzschia persuadens, originalmente descrita a partir de águas estuarinas da Laguna de Veneza, é uma diatomácea raramente citada na literatura desde a sua proposição e é registrada aqui pela primeira vez em ambiente epicontinental da América do Sul. Características morfológicas desta espécie, tais quais valva levemente panduriforme, com uma ondulação reta longitudinal na face valvar, areolas poroidais e sistema de rafe fortemente excêntrica, claramente atribui esta ao gênero Tryblionella, e a sua transferência foi feita. São apresentadas novas observações sobre a morfologia da frústula e comparações com espécies afins. Análises em microscopia óptica de eletrônica de varredura de Tryblionella persuadens comb. nov. do rio Cachoeira, Nordeste do Brasil, foram documentadas.
