Examination of the syntypes of Lepadogaster minimus Döderlein in Steindachner and Döderlein 1887 showed that species to be identical with Kopua japonica Moore, Hutchins and Okamoto 2012, although long been regarded as a valid species of Aspasma. [] Key Result A species commonly regarded as Aspasma minima is described as the new species Aspasma ubauo sp. nov., on the basis of 58 specimens from the Japanese mainland, and characterized by the following characters: 5–7 dorsal-fin rays; 6–8 anal-fin rays; 19–22…
