Morphological and molecular studies on topotype material of Neoralfsia expansa (Phaeophyceae) reveal that Asian specimens assigned to this taxon are genetically distinct
Abstract
The genus Neoralfsia was newly described by P.-E. Lim and Kawai on the basis of rbcL sequence data from specimens from Japan and Malaysia identified as Neoralfsia expansa, and N. expansa [Myrionema (?) expansum] from Mexico was designated as the type species. Our maximum likelihood and Bayesian analyses show that specimens of N. expansa from the type locality are grouped into a new, not previously described, clade in Neoralfsiaceae, distant from that of the putative specimens attributed to N. expansa from Japan and Malaysia. We show that genuine “expansa” does not include Asian material. The distribution of the species is not as wide as has been previously recorded.
