New combination in Colaconema (Colaconematales, Rhodophyta), addition to marine algae from Northeastern of Brazil

Alana Araujo dos Santos Carlos Wallace do Nascimento Moura About the authors


During a study on epiphyte algae of Acetabularia crenulata from Itaparica Island, Bahia, Brazil, specimens of the genus Colaconema were collected and identified as Colaconema hypneae (Börgesen) comb. nov., which previously was considered Acrochaetium hypneae (Börgesen) Börgesen. This nomenclatural proposal is based on plastids morphology, distinctive character of the genus. Description, illustrations, comparisons among related taxa are presented, as well as the extension of its geographic distribution to the northeastern coast of Brazil.

Key words:
Colaconemataceae; epiphyte; northeastern; plastid; Taxonomy
