A new species of the genus Amakusanthura azumai (Crustacea: Isopoda: Anthuridae) is described based on a number of specimens collected from Yuya Bay, on the Sea of Japan side of Yamaguchi Prefecture in western Honshu. The present new species is most closely allied to Amakusanthura longiantennata Nunomura, 1977. The former is differentiated from the latter by the following characteristics: in the rounded medial process and the antero-lateral process of cephalon, the rounded tip of the masculina of the second male pleopod, less numerous teeth on the maxillula, shorter maxillipeds, a wider propodus on the pereopdl, a lack of dorsal pits on the dorsal surface of the pereonal somites, and less numerous setae on the pereopods.
