The validity of the poorly known monotypic scorpionfish genus Hipposcorpaena Fowler is confirmed, and H. filamentosa Fowler is redescribed. The genus is characterized by the following characters: dorsal fin with 12 spines and 9 soft rays; anal fin with 2 spines and 6 soft rays; pectoral fin with 14 rays; lower pectoral fin rays slender, filamentous; longest ray extending well beyond vertical from posterior end of anal fin base; all dorsal and anal fin soft rays (except last ray of each fin divided into 2 at base), and all pectoral and caudal fin rays unbranched; head and body strongly compressed; body deep, depth 39.5%~41.2% of standard length; body covered with small cycloid scales; no palatine teeth; interorbital ridges present; tympanic spine present; posttemporal spine simple, lacking upper posttemporal spine; lower caudal fin with 1~4 distinct black spots, greater in width than orbit diameter; mature adult size at least 35.2 mm SL.
