Abstract
Species of Volvox sect. Volvox (Volvocaceae, Chlorophyceae) are unique because they have thick cytoplasmic bridges between somatic cells and spiny-walled zygotes. This section is taxonomically important because the genus Volvox is polyphyletic. However, taxonomic studies of species in Volvox sect. Volvox have not been carried out since 1944. Here we performed a taxonomic study of monoecious species of Volvox sect. Volvox based on the comparative morphology and molecular phylogeny of chloroplast genes and the internal transcribed spacer regions (ITS) of nuclear ribosomal DNA (rDNA) using various strains originating from Japan and two preserved strains from USA. The strains were clearly divided into four species, V. globator L., V. barberi W. Shaw, V. kirkiorum Nozaki et al. sp. nov. and V. ferrisii N. Isaka et al. sp. nov., on the basis of differences in numbers of zygotes (eggs) in the sexual spheroids, form of zygote wall and somatic cell shape. Sequences for ITS of nuclear rDNA resolved that the two new species have phylogenetic positions separated from V. globator, V. barberi, V. capensis F. Rich et Pocock and V. rousseletii G. S. West within Volvox sect. Volvox.
