Etymology. Lute for yellow and vitta for stripe from Latin, in reference to the longitudinal yellow stripe extending from the pectoral fin base to the caudal fin base on the body of this species.
Distribution. Known from Tosa Bay, southern Japan, and northern and southern Taiwan. It could be also distributed to Vietnam (Prokofiev, 2008) (Fig. 2). Depth range is from 50 to 100 meters.
Barcode sequence. The 633-bp sequences of the mitochondrial cytochrome c oxidase subunit I (CO I or COX I) gene were bidirectionally sequenced for the holotype (ASIZP 0 71627, GenBank accession no. FN677936) and 14 paratypes (USNM 398144 and ASIZP 071628 -71630, GenBank accession no. FN677937 -677938, and FN677939 -950, respectively). The 15 sequences were closely matched with 0.1% K2P genetic divergence.
