抄録

We describe a new species of Fredericqia (Phyllophoraceae, Rhodophyta) from the Choshi Peninsula, Japan (previously listed as 'Gymnogongrus incurvatus nom. nud.') based on morphological and molecular analyses. We assign the binomial Fredericqia chiharae sp. nov. to this new entity. Our combined rbcL, cox1, and 28S rDNA analyses suggested that F. chiharae belongs to genus Fredericqia, and is distinct from other Fredericqia species. Fredericqia chiharae is characterized by a flattened incurved thallus, marginal proliferations, dioecious gametophytes and a procarp consisting of a three-celled carpogonial branch situated on a supporting cell and bearing a sterile lateral on the basal cell. The cystocarpic characteristics of F. chiharae, i.e. a cystocarp loosely immersed in the medulla, the absence of secondary medullary cells around the cystocarp and the presence of multiple carpostomes, are congruent with those of Fredericqia. Fredericqia chiharae is the first representative of the genus to be reported from the northwestern Pacific.
