Abstract:
Osmundea purepecha Sentíes, Mendoza-González & Mateo-Cid, n. sp.,
is proposed from Zapote, Michoacán, tropical Mexican Pacific coast, on the basis
of comparative morphology and rbcL sequence analysis. This species has characteristics
typical of the genus Osmundea, including two pericentral cells per axial
segment and male gametophytes with a filament type reproductive structure.
Spermatangial branches are simple, terminating in one or two spherical sterile
cells, developing in pocket-shaped pits located at tips of branchlets. Phylogenetic
position of this species was inferred by analysis of chloroplast-encoded rbcL
gene sequences from 33 taxa, including one member of the Ceramiaceae as an
outgroup. The Mexican Pacific sample, from Zapote, formed a distinctive and
well-supported basal clade segregated from other Osmundea species. Osmundea
purepecha, n. sp., is morphologically and genetically distinct from other Osmundea
species, supporting the assignment of this new taxon.
