背棘 (总数) : 2. Pelvic rays usually 11. Underside of head mostly scaled, but a median-ventral naked swath below snout tip; pores of sensory system on head relatively small. Scales densely covered with narrowly to broadly lanceolate spinules in somewhat convergent rows; 7.0-8.5 rows below second dorsal origin; 34-40 lateral line scales over distance equal to predorsal length. First dorsal fin dusky to black. Anterior dermal window of light organ between insertions of pelvic fins. Barbel 1.8-2.0 into orbit diameter, 15-20% of HL; preoral length 23-28%; orb.-preop. 38-44%.
腹鳍鳍条通常 11. 头部的下面大部份覆有鳞片的, 但是在吻顶端之下的一个腹面中央的裸露一大片; 在头部上的知觉系统的孔相当小的。 鳞片厚密地狭窄地对在略微趋集于一点的列中宽广矛尖形的小刺覆盖着了; 7.0-8.5 在第二背鳍起源之下的列; 在距离上的 34-40个侧线鳞片等于前背的长度。 第一背鳍暗色到黑色的。 在腹鳍嵌入点之间的发光器的前面皮窗。 进入眼窝直径之内的触须 1.8-2.0,15-20% HL; 口前长度 23-28%; 眼窝-preop。 38-44%.
A benthic species found on the continental slope (Ref. 75154).
