Abstract

This paper contributes to expanding the documented freshwater red algal flora of the Philippines, a country historically underrepresented in comparison to its Southeast Asian neighbours. It reports the discovery of four species previously unrecorded in the country’s freshwater algal flora. These species were collected from clear, cool, fast-flowing streams within well-shaded, lowland rainforests in the provinces of Bataan and Cavite on Luzon Island. The newly identified species are Audouinella cylindrica C.-C.Jao, Audouinella glomerata C.-C.Jao, Kumanoa montagnei Entwisle, M.L.Vis, W.B.Chiasson, Necchi & A.R.Sherwood, and Kumanoa tiomanensis (S.Kumano & Ratnasabapathy) Necchi & M.L.Vis. The paper provides detailed descriptions of their morphological characteristics, habitats, and collection localities, alongside a key to the species of Kumanoa recorded in the country. This study highlights the ecological and taxonomic significance of these newly identified species and emphasizes the need for more extensive surveys to address biodiversity gaps in the region.
