We describe a new capitellid species, Mastobranchus uru sp. nov., from a tidal flat on Iriomote Island, Okinawa, southern Japan. This species differs from its three congeners in having capillary chaetae only on the notopodia in chaetiger 1 and in the number and arrangement of teeth on hooks. We also provide for this new species a barcode nucleotide sequence from the mitochondrial 16S rRNA gene.
