Abstract
Plants of the red algal genus Parviphycus are typically diminutive and often occur in mixed stands with other turf species, leading to considerable difficulty in locating them in the field. Once sorted, identification to genus and species is challenging because of their lack of conspicuous diagnostic features. Examination of the type specimen and fresh collections of Gelidiella myrioclada from Singapore revealed that this species may be incorrectly classified to Gelidiella. To test the taxonomic position of G. myrioclada, phylogenetic analyses using rbcL and cox1 data were performed. Parviphycus comprised two clades that corresponded to geographical distributions in the Atlantic and the Indo-Pacific. In all analyses, G. myrioclada was consistently resolved in the Indo-Pacific Parviphycus clade, along with Parviphycus antipae and Parviphycus sp. Based on morphology, G. myrioclada shows subapical growth and tetrasporangial characteristics that are unique to Parviphycus. We therefore, propose the assignment of G. myrioclada as Parviphycusmyriocladus (Børgesen) comb. nov.
