背棘 (总数) : 2. Snout about equal to orbit diameter; anterolateral margin incompletely supported by bone; orbit about equal to postorbital length; upper jaw extends to beyond vertical through middle of pupil, not restricted at lateral corners; barbel long, slightly shorter than orbit diameter; subopercle with narrow pointed ventral tip. Light organ extends from anus almost to isthmus. Anus immediately before anal fin. Naked areas on head include underside of snout and lower jaws, nasal fossae, and most of suborbital region. Body scales covered with needlelike spinules arranged in 10-14 more-or-less parallel rows, the individual spinules separate and non-overlapping. First dorsal and pelvic fins with distinct black tips; branchiostegal membrane with pronounced black blotch dorsally; posterior end of anal black; mouth pale.
Body shape (shape guide): elongated.
吻大约等于眼窝直径; 前外侧的边缘不完全地由硬骨支撑了; 眼窝大约等于眼眶后的长度; 上颌延伸到超过垂直的经过瞳孔的中央, 不在侧面的角落限制; 触须长的, 略短的超过眼窝直径; 鳃盖有狭窄的尖腹的顶端。 发光器延伸从肛门几乎到峡部。 在臀鳍正前方的肛门。 在头部上的裸露区包括吻部下面与下颚，鼻的小窝与大部分的眶下区域。 身体鳞片覆盖着排列成 10-14 的针状小刺约略平行的列了, 个别的小刺分开与非部分重叠的。 第一背鳍与腹鳍有明显的黑色顶端; 鳃盖薄膜背面有明显的黑色斑块; 肛门黑色的后端; 嘴灰白的。
