MATERIAL EXAMINED (2 spec.).— NET: ASIZP 65232 (1, 165 TL) , Da-xi. ASIZP 70247 (1, 97 TL) , Da-xi.

DISTINGUISHING FEATURES.— 1D II 9–12; P i18–i22; V 8; inner GR-I 12–15 total; pyl. caeca 11–18. Snout depressed, nasal bones developed into three horizontal platelike processes; body subcylindrical; outer V ray produced and expanded distally. Attains 240 mm TL.

DISTRIBUTION.— Pacific coast of s. Japan, and ne. Taiwan. in 350–650 m.

REMARKS.— Shao et al., (2008: table 2) first recorded the species from Taiwan based on ASIZP 65232. The species is apparently relatively abundant off Japan, as suggested by the 95 specimens (143–211 mm TL) recorded by Okamura (1970 b:4, table 1), who treated it as a subgenus of Hymenogadus . Kamohara (1961) designated a neotype for the species but not in a revisory work, which renders the designation invalid (fide Eschmeyer 1998:852).
