型态特徵 | 形态测量图
This species (probably of medium size) is distinguished by the following set of characters: a small but conspicuous preorbital thorn; velvety dorsal surface of disc which is covered with fine denticles; velvety ventral surface with widely spaced and very fine denticles; long and slender tail, entirely velvety and without enlarged thorns; lateral tail folds are not expanded distally, narrower than tail for their whole length; nasal lobes are not greatly expanded, width of nasal curtain 7.3-8.3% TL; relatively small mouth, width more than 66% of maximum width of nasal curtain and 5.7-6.2% TL; anterior pelvic-fin lobe is shorter than posterior lobe; dorsal surfaces plain pale yellowish brown, ventral surface creamy white; total pectoral-fin radials 64-66, monospondylous centra 25, total diplospondylous centra 119-127, total number of centra 144-152 (Ref. 91035).
Found on nearby insular slope. Life history unknown (Ref. 114953).
