Etymology: Phenacoscorpius: Greek, phenax, -akos = deceptive + Greek, skorpion = scorpion (Ref. 45335). More on author: Fowler.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 68 - 622 m (Ref. 10482). Deep-water; 40°N - 4°S, 107°E - 150°W (Ref. 92340)
Pacific: Taiwan, Vietnam, Philippines, Indonesia, and Hawaii; northernmost record Emperor Seamounts. Apparently restricted to the North Pacific (temperate to tropical) and reports from New Zealand and New Caledonia are based on misidentifications.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 13.5 cm TL male/unsexed; (Ref. 28618); common length : 5.1 cm SL male/unsexed; (Ref. 10482)
soft rays: 5. Lachrymal bone consisting of 2 spines over maxillary, first as a broad lobe, second as a broad spine pointing down; well marked suborbital ridge with 5 or 6 or more spines; second preopercle spine small or absent (Ref. 10482). Distinguished from other Hawaiian scorpionfishes by having only the anterior 4 or 5 tubed lateral line scales present, with the remainder of the lateral line absent; and presence of large melanophores on the caudal peduncle (Ref. 10482).
Benthic (Ref. 58302). Feeds on small fishes and crustaceans (Ref. 5755). Female specimens (4.70-5.59 cm SL) taken from the Emperor Seamounts have mature gonads filled with relatively large eggs of several developmental stages with the most developed eggs are ca. 0.4 mm in diameter (Ref. 92340).
