Phycologia 49: 97–103. DOI: 10.2216/09-24.1 This study evaluated the species-level taxonomy and phylogenetic relationship among Kumanoa species from Brazil with other regions of the world based on the plastid-encoded RUBISCO large subunit gene (rbcL). Partial rbcL sequences were obtained for 11 Kumanoa specimens. Eight species are recognised from Brazil on the basis of molecular and morphological data: seven previously described (K. abilii, K. ambigua, K. breviarticulata, K. cipoensis, K. equisetoidea, K. globospora and K. procarpa) and a new species here proposed (K. amazonensis sp. nov. Necchi & Vis). The new species has reduced and dense whorls but differs from the two closest related species in lacking secondary fascicles. Previously proposed infrageneric categories were not supported by the molecular data. Sp...
