Abstract

Species level taxonomy and phylogeographic distribution patterns in the freshwater rhodophyte Sirodotia Kylin are resolved through phylogenetic inferences based on rbcL and cox2-3 sequence data. Previous studies focused on the taxonomy of specific Sirodotia species or the distributions across a limited geographic region. Our molecular phylogenies include samples attributable to five recognized Sirodotia species and include collections from Australia, Brazil, Costa Rica, Canada, Finland, Mexico, New Zealand, South Africa, and the United States. Both rbcL and cox2-3 phylogenies inferred S. suecica Kylin, S. tenuissima (Collins) Skuja ex Flint, and S. goebelii Entwisle et Foard as a monophyletic group with little sequence divergence. This result supports the synonymy of S. tenuissima and S. goebelii with S. suecica (the species name with priority). Within the aforementioned clade, samples collected from Australia and New Zealand formed a monophyletic group with no other discernible phylogeographic patterns within S. suecica. This result seems to be somewhat unusual in the Batrachospermales as other species have shown greater genetic variation among geographically distant locations. Like previous studies, S. huillensis (Welwitsch ex W. & G.S. West) Skuja and S. delicatula Skuja were inferred as a separate species based on the rbcL phylogeny and supports the current taxonomy. A specimen labeled S. aff. huillensis from South Africa, may represent a new species, however, further research is necessary before it can be designated as such.
