簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 107 - 120; 臀鰭軟條: 97 - 103; 脊椎骨: 113 - 120. Diagnosis: Distinguished from the majority of its congeners (46 of 61 currently recognized species) by the ventral position of the lateral line. Among species of Lycodes with a ventral lateral line, the new species is distinguished from brevipes, diapterus, hubbsi, microporus, nakamurae, nishimurai, and ocellatus by the absence of scales on the nape. It is distinguished from all remaining congeners except pectoralis and vahlii by its comparatively high vertebral count (113-120 vs. 94-113 in brunneofasciatus, caudimaculatus, frigidus, gracilis, and obscurus). It is distinguished from pectoralis and vahlii by the presence of an interorbital pore, number of anal-fin pterygiophores preceding the first haemal spine (5-7 vs. 2-4), and the color pattern (pectoralis and vahlii lack light bands on the dorsal fin, light blotches on the upper body, and the bicolor appearance of the head, body, and pectoral fin) (Ref. 56970).
鑑別: 與多數的它的同類 (61 中的 46 現在公認的種) 側線的藉由腹位置區分了。 在 Lycodes 的種之中具有一個腹的側線, 新種被與 brevipes ， diapterus ， hubbsi 區分, microporus, nakamurae, nishimurai, 與 ocellatus 在後頸上的藉由缺少鱗片。 它是除了 pectoralis 與 vahlii 以外與所有的剩餘同類區分用它的比較高脊椎骨數.(113-120 vs.94-113 在 brunneofasciatus ， caudimaculatus ， frigidus ， gracilis 與 obscurus 中) 它是藉由與 pectoralis 與 vahlii 區分有一個眼間骨孔, 臀鰭支鰭骨的數字在第一個脈棘 (5-7 和 2-4 比較), 與顏色圖案 ( pectoralis 與 vahlii 缺乏淡色的條紋在背鰭上, 光斑塊在身體上半部上, 與頭部，身體與胸鰭的雙色外表) 之前.(參考文獻 56970)
The species were collected in hauls dominated by Atheresthes stomias, Theragra chalcogramma, Hippoglossus stenolepis, and Sebastes alutus; also with Lycodes diapterus and L. concolor. Bottom temperatures of collection sites ranged from 3.3-4.3 °C. Stomach contents of 2 specimens has partially digested sea urchin tests (Ref. 56970).
此魚種被收集在拖網被 Atheresthes stomias ， 狹鱈〔Theragra chalcogramma〕 ， Hippoglossus stenolepis 與 Sebastes alutus 控制; 也有 Lycodes diapterus 與 L. concolor 。 底部採集點範圍從的溫度 3.3-4.3個 ° C. 2件標本的胃內含物已經部份地消化海膽測試。 (參考文獻 56970)
