簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 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.
吻大約等於眼窩直徑; 前外側的邊緣不完全地由硬骨支撐了; 眼窩大約等於眼眶後的長度; 上頜延伸到超過垂直的經過瞳孔的中央, 不在側面的角落限制; 觸鬚長的, 略短的超過眼窩直徑; 鰓蓋有狹窄的尖腹的頂端。 發光器延伸從肛門幾乎到峽部。 在臀鰭正前方的肛門。 在頭部上的裸露區包括吻部下面與下顎，鼻的小窩與大部分的眶下區域。 身體鱗片覆蓋著排列成 10-14 的針狀小刺約略平行的列了, 個別的小刺分開與非部分重疊的。 第一背鰭與腹鰭有明顯的黑色頂端; 鰓蓋薄膜背面有明顯的黑色斑塊; 肛門黑色的後端; 嘴灰白的。
