Description synthétique
Morphologie | Morphométrie
Épines dorsales (Total): 2. Snout moderately pointed, 1.4-1.6 times orbit diameter; anterolateral margin incompletely supported by bone; upper jaw slightly less than 1/3 HL; orbit 1.5-1.8 into postorbital length; subopercle produced into slender point ventrally, the tip protruding slightly beyond angle of preopercle. Color overall dark chocolate brown. Nasal fossa with small scales on anteroventral corner but otherwise naked. Spinules on body scales below dorsal interspace imbricate, broadly trihedral, with wide lateral buttresses, in 3-5 saw-toothed, divergent rows. Anus immediately anterior to anal fin; no external sign of light organ.
A benthic species found on the continental slope (Ref. 75154).
