Abstract:
Critical reinvestigation of the four presently recognised species of the green macroalgal genus Chamaedoris (C. auriculata, C. delphinii, C. peniculum and C. orientalis) based on morphological and molecular data reveals that at least one species, C. orientalis, is actually a member of the genus Struvea and is herein transferred to that genus as S. okamurae nom. nov. This has also necessitated a revised circumscription of the genus Struvea. It is also shown that morphological features traditionally used to delimit the three species of Chamaedoris (shape of capitulum and number of cells split off from the distal pole of the stipe) are not diagnostic, and that the traditional species delineations need to be re-assessed. Detailed morphological and morphometric analyses reveal that more subtle differences exist between the three species, including cell dimensions and crystalline cell inclusions. Substantial new collections over the last 27 years allows us to update knowledge of their biogeographic distributions, assess their interrelationships, and determine their molecular phylogenetic relationships with species of the closely related genera Apjohnia, Boodlea, Cladophoropsis, Phyllodictyon and Struvea.
