A single specimen (HUMZ 177334, 88.5 mm in standard length) of a stichaeid fish, Leptoclinus maculatus diaphanocarus (Schmidt, 1904), was trawled in depths of 121.4-121.6m, inOkhotsk Sea, off Esashi in the northern part of Hokkaido, in August 1999. It represents the first reliable record of the subspecies based on the specimen from Japan and the southernmost record of the subspecies. Previous confusion about Japanese names for two subspecies of L. maculatus was reviewed.
