Resumo: | In Brazil, only five species of Haslea Simonsen have been found, probably due to their rarity and extremely hyaline valve, though presenting relatively large dimensions. In this study, three species from different localities in southern Brazil were investigated using transmission electron microscopy. Haslea cf. karadagensis Davidovich, Gastineau & Mouget has several discrepant features compared to the original description of H. karadagensis, such as fewer longitudinal striae. The specimens found did not completely conform to the diagnosis of H. ostrearia (Gaillon) Simonsen, a very close species recorded previously in the region, since there are differences regarding transapical and apical axes. Our material of Haslea wawrikae (Hustedt) Simonsen fit the dimensions of valves found elsewhere, except for a slightly higher number of striae. The newly reported species Haslea nautica (Cholnoky) Giffen resembled the valve structure of H. wawrikae regarding longitudinal strips and areolae. |

Neste trabalho, três espécies foram investigadas em microscopia eletrônica de transmissão, provindas de diferentes localidades do sudeste e sul do Brasil. Haslea cf. karadagensis Davidovich, Gastineau & Mouget em nosso material possui algumas características distintas de H. karadagensis como um número menor de estrias longitudinais. Estes espécimes certamente não se encaixam bem em H. ostrearia (Gaillon) Simonsen, previamente citada para a região, devido à diferenças de medidas de eixos apical e transapical. Haslea wawrikae (Hustedt) Simonsen encaixou-se nas dimensões de valvas encontradas em outras regiões, exceto por um número ligeiramente maior de estrias. Haslea nautica (Cholnoky) Giffen é um novo registro para a América do Sul, e mostrou estrutura da valva semelhante à H. wawrikae em relação á arquitetura das faixas longitudinais e aréolas.Iheringia.
