簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 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%.
腹鰭鰭條通常 11. 頭部的下面大部份覆有鱗片的, 但是在吻頂端之下的一個腹面中央的裸露一大片; 在頭部上的知覺系統的孔相當小的。 鱗片濃密地狹窄地對在略微趨集於一點的列中寬廣矛尖形的小刺覆蓋著了; 7.0-8.5 在第二背鰭起源之下的列; 在距離上的 34-40個側線鱗片等於前背的長度。 第一背鰭暗色到黑色的。 在腹鰭嵌入點之間的發光器的前面皮窗。 進入眼窩直徑之內的觸鬚 1.8-2.0,15-20% HL; 口前長度 23-28%; 眼窩-preop。 38-44%.
A benthic species found on the continental slope (Ref. 75154).
