DISTINGUISHING FEATURES.— 1D II 8–10; P i11–i16; V 8 (rarely 7 or 9); inner GR-I 16–22 total; pyl. caeca 10–17. Orbit circular, large 34–45% HL, 0.9–1.0 into postorbital; upper jaw 48–59%. Head deep, length about 6–7 in TL; body depth about 8–9 in TL. Snout bluntly rounded but with short terminal point, barely projecting beyond mouth. Upper jaw extends to vertical through posterior margin of orbit. Barbel about 1 ⁄ 3 orbit. Attains about 200 mm TL.
DISTRIBUTION.— South China Sea off Hong Kong, Taiwan, and Luzon, Philippines, and ne. Taiwan, in 445–1188 m , but mostly between about 300 and 550 m.
REMARKS.— Gilbert and Hubbs (1920) recognized three subspecies of this species: H. striatissimus striatissimus , H. striatissimus aeger , and H. striatissimus torvus . The last was originally described as a full species by Smith and Radcliffe (in Radcliffe 1912). Okamura (1970:50–54) described H. s. hachijoensis from two specimens taken off Hachijo, a group of remote islands about 180 nautical miles s. of Tokyo; Okamura in Masuda et al. (1984:93) elevated the taxon to full species. Sazonov (1994:101–102) later recorded two additional specimens from the Northwest Pacific Ridge (Emperor seamounts) and one from the Kyushu-Palau Ridge. It is distinguished from H. s. striatissimus by “the longer barbel, the larger head, the smaller eye, and the lower snout” ( Okamura 1970:53).
