Description
Summary:	This study reports the first occurrence of Trichodesmiumthiebautii Gomont ex Gomont on the coast of northeastern Brazil. Samples were gathered during the rainy season (July 2005) and the dry season (November 2006) at six stations distributed along two perpendicular profiles of the coast of Pernambuco (8º18'S - 34º56'W and 8º32'S - 35º00'W). T. thiebautii was found during both periods of the year and at the six collection stations, forming colonies in the form of clusters or more rarely, bundles, with straight cylindrical trichomes, quadratic or slightly longer cells, with widths between 5-10 µm and heights of 3-15 µm. The hydrological variables presented small variations, contributing to wide distribution of the species. Este estudo relata a primeira ocorrência de Trichodesmiumthiebautii Gomont ex Gomont no litoral do Nordeste do Brasil. As amostras foram coletadas durante o período chuvoso (julho de 2005) e de estiagem (novembro de 2006), em seis estações distribuídas em dois perfis perpendiculares à costa do estado de Pernambuco (8º18'S - 34º56'W e 8º32'S - 35º00'W). T. thiebautii foi registrada durante os dois períodos anuais e nas seis estações de coleta, formando colônias em forma de tufos ou raramente em feixes, com tricomas cilíndricos, retos, células quadráticas ou ligeiramente mais longas, largura entre 5-10 µm e altura de 3-15 µm.
