ARAKAKI, NATALIA; ALVEAL, KRISLER; RAMIREZ, MARÍA ELIANA y FREDERICQ, SUZANNE. The genus Callophyllis (Kallymeniaceae, Rhodophyta) from the central-south Chilean coast (33° to 41° S), with the description of two new species. Rev. chil. hist. nat. [online]. 2011, vol.84, n.4, pp. 481-499. ISSN 0716-078X. doi: 10.4067/S0716-078X2011000400002.
The taxonomic status of the species in the genus Callophyllis Kützing (Kallymeniaceae, Rhodophyta) from central-south Chile (33° to 41° S) is examined on the basis of morphological and molecular evidence. Of the four species originally cited for central Chile, C. variegata, C. pinnata, C. atrosanguinea and C. laciniata, only the presence of C. variegata has been confirmed in this study. C. pinnata reported from Chile is found to be different from C. pinnata described from California, and it is here newly described as C. concepcionensis sp. nov. C. atrosanguinea from southern Chile (including C. linguata from the Antarctic Peninsula) is distinct from the species called C. atrosanguinea from central-south Chile, the latter which is here described as C. macrostiolata sp. nov. C. variegata, C. concepcionensis and C. macrostiolata are distinguished from one another by their external habit, the nature and distribution of their cystocarps, and the female reproductive morphology. Comparative rbcL sequence analysis corroborates the distinction of these taxa from central-south Chile and their relationships to other species worldwide.
