Resumen:
Schizymenia dubyi (Chauvin ex Duby) J. Agardh is a red alga of the order
Nemastomatales that is native to Europe, Asia and Oceania. The first
specimen of this seaweed from the Argentinian coast was collected in
the Chapadmalal intertidal wave-cut platform (38º 12 S, 57º 40 W) in
September 2008. Taxonomic identification of the species was made on the
basis of vegetative and reproductive characters and confirmed by DNA
sequence analysis of the rbcL gene. The S. dubyi samples collected in
the field were represented by foliose gametophytes as well as crustose
tetrasporophytes. The gametophytes were distributed in patches of c. 50%
coverage of the analysed quadrants (n20). Gametophyte abundance was
3.1 ± 2.5 (mean ± SD) plants per quadrant (0.04 m2). All these were
fertile females. Molecular results placed the specimens from Argentina
within the S. dubyi clade, closely related to S. dubyi from Japan and
France.
