Two monogonont rotifers, Brachionus bidentatus Anderson, 1889 and Scaridium montanum Segers, 1995, were identified during a survey on Gyodongdo Island, Korea. The specimens were collected from freshwater habitats using a 50 μm plankton net. The morphological characteristics of the Korean B. bidentatus specimens correspond well with previous descriptions, particularly with the anterolateral spines being the longest among the six anterior spines and unique patterns of dorsal lorica facets. The Korean S. montanum specimens resemble the morphological data of previous studies, exhibiting rami without alulae and consistent trophi characteristics. This study presents the morphological diagnoses of two new records from Korea, supplemented by scanning electron microscopy images of the habitus and trophi for each species.
