Two new marine gastrotrichs of the genus Thaumastoderma are described from South Korea. T. coronarium sp. nov. was collected from the intertidal zones of Manripo beach and Sopori, Tokchok Island in the Yellow Sea. This species seems to be most closely related to T. bifurcatum Clausen, 1991 or T. truncatum Clausen, 1991 in that they share the following characteristics: one pair of simple, spatulate tentacles; six pairs of dorsal cirri; and absence of eye spots. It differs from these species in having four conspicuous head papillae and a different arrangement of dorsal cirri. T. appendiculatum sp. nov. was collected from the intertidal and shallow sublittoral zones of Pongpo beach, Sokcho in the East Sea of Korea, and is easily distinguished from its congeners in having a pair of stout adhesive tubes on the posterior trunk margin, and in that it frequently possesses accessory dorsal cirri. This is the first report on marine gastrotrichs from Korea, and the first record of the genus Thaumastoderma in East Asia.
