Five newly recorded species of cyanobacteria in Korea are Sphaerospermopsis reniformis (Aphanizomenona- ceae) from Chungju-si, Chungcheongbuk-do; Pelatocladus maniniholoensis (Hapalosiphonaceae) from Ulleung-gun, Gyeongsangbuk-do; Tolypothrix carrinoi (Tolypothrichaceae) and Myxacorys chilensis (Lepto- lyngbyaceae) from Suwon-si, Gyeonggi-do; and Tildeniella torsiva (Oculatellaceae) from Gunsan-si, Jeolla- buk-do. These species are morphologically similar to each of its corresponding type species, and clustered in the same clade with respective type species in the phylogeny using 16S rRNA. The similarity of 16S rRNA sequences was more than 98.5% with each of its respective type species.
