Abstract

We performed a taxonomic study on Korean freshwater bryozoans with the materials collected from 70 localities during 2014 to 2016. A total of 14 Korean freshwater bryozoans are reported through this study. Among them, three Plumatellids, Plumatella fungosa (Pallas, 1768), P. repens (Linnaeus, 1758), and P. reticulata Wood, 1988, are newly added to the Korean fauna. Three species were redescribed with only their statoblasts: Lophopodella carteri, Plumatella rugosa, and Stephanosella hina (Seo, 1998; 2005; Chae et al., 2016). Their colonies were found in Korea for the first time in this study. Since Fredericella sultana, Hyalinella punctata, and Plumatella casmiana were reported from Korea (Toriumi, 1941), neither statoblast nor colony has been found, but we observed them. Living colonies of six species were photographed in the field. Furthermore, the statoblasts of nine species, including three species new to the Korean fauna, were also documented using scanning electron microscopy.
