Abstract: There are 16 species of the red algal order Rhodymeniales reported from North
Carolina waters. One, Asteromenia peltata, is the only described species in its genus and is
reported from the Atlantic, Pacific and Indian oceans. Sequences of the 18S rRNA gene
from North Carolina and Bermuda specimens of A. peltata were different at five sites and
differed from a sequence attributed to A. peltata from Western Australia at 74 and 73 sites
respectively. Phylogenetic analyses of 18S rRNA gene sequences from 25 Rhodymeniales
species resolved the North Carolina and Bermuda taxa in a monophyletic clade that was
distinctly separated from the clade containing the Western Australian taxon. The type
specimen of A. peltata is from Venezuela so the Atlantic taxon is retained within
Asteromenia, but the large sequence divergence and separation of the Atlantic and Western
Australia taxa in phylogenetic analyses indicates that a new genus name is required for the
latter taxon. The number of differences between the North Carolina and Bermuda
specimens is within the reported range of between species differences, and suggests that
they represent separate Asteromenia species.
