Volvulina Playfair is a colonial volvocalean genus with usually 8 or 16 cells forming hollow ellipsoidal colonies. In this study, a strain of Volvulina was isolated from Lake Tsukui, Kanagawa Prefecture, Japan. This strain was morphologically identified as Volvulina compacta Nozaki, which was previously known only from strains isolated from Nepal. Chloroplast multigene analyses using rbcL, atpB, psaA, psaB and psbC genes showed that the Japanese strain of V. compacta is closely related to the Nepalese strain of V. compacta and to an American strain of Volvulina pringsheimii Starr, but only distantly to Volvulina steinii Playfair previously reported from Japan. Although the Japanese strain was more closely related to V. pringsheimii than to Nepalese V. compacta, it was clearly distinguished from V. pringsheimii by its square cell shape in the top view. These results indicate the existence of cryptic species within V. compacta.
