Antithamnionella multiglandulosa sp. nov. (Rhodophyta, Ceramiaceae) from the Atlantic Iberian Peninsula

Keywords: Antithamnionella, Atlantic Iberian Peninsula, Ceramiaceae, Rhodophyta, taxonomy

Antithamnionella multiglandulosa is described as a new species from the Atlantic side of the Iberian Peninsula. Distinguishing features of the new species are: the 3–6 simple whorl-branches produced per axial cell, the presence of series of up to 4 gland cells on whorl-branches, and whorl-branches with periaxial cells similar in size to contiguous branch cells. We present a comparative study of European or other similar Antithamnionella species, including A. ternifolia, A. elegans, A. spirographidis, A. boergesenii, A. multiramosa, A. verticillata, A. tormentosa and A. australis. There are now five species of Antithamnionella in northern Spain and Portugal, and six along the European Atlantic coasts.
