Virescentia guangxiensis, a new species of Virescentia from Guangxi, South China, is described and illustrated based on morphological observations and phylogenetic analysis. This species was distinguished morphologically from other species by the presence of special expansion cells with a variable shape, obovoid, spherical, pear-shaped, located in the penultimate cells of primary or secondary fascicles, rarely terminal on primary fascicles, as well as by small whorls (250-350-μm wide) and short primary fascicles (5-7 cell stories). Phylogenetic analysis of molecular data from the rbcL and COI-5P loci supported the separation of the proposed new species from other species in the genus Virescentia. This is the first species of the order Batrachospermales reported in Guangxi and the second species of the genus Virescentia reported in China. This study expands the known species diversity and geographical distribution of freshwater Rhodophyta in China.
