Abstract

A new monogonont rotifer, Cephalodella binoculatasp. nov., was described from a soil sample collected in Korea. The new species is morphologically similar to C. carina but is distinguished by having two frontal eyespots, a vitellarium with eight nuclei, and the shape of its fulcrum. We also described four other cephalodellid species collected in Korea; Cephalodella auriculata, C. catellina, C. gracilis, and C. tinca. Of these four species, C. gracilis and C. tinca were newly recorded in Korea. We provided the morphological characteristics of the five Cephalodella species along with photographs of trophi observed with a scanning electron microscope. Furthermore, we provided the mitochondrial cytochrome c oxidase subunit I gene sequences of the five species.
