- Abstract
A trachichthyid specimen (308.8 mm in standard length [SL]) collected from the continental slope off Sanriku, Pacific coast of northern Japan, was examined morphologically. This specimen was identified as Hoplostethus crassispinus Kotlyar, 1980 by having deep body, dorsal fin with six spines and 12 soft rays, 19 total gill rakers on first arch, 26 total vertebrae, 13 scutes on ventral midline of abdomen, and black coloration on the membrane between dorsal fin spines. This species had been known only from small specimens less than 250 mm SL collected from the restricted deep waters off southwestern Japan, and the present specimen is recognized as the largest record of H. crassispinus from the northernmost water around the Japanese archipelago.
