簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 4 - 6; 臀鰭軟條: 4; 脊椎骨: 18 - 19. Tubercles on sides of tail with extremely long spines. Small tubercles on ventral surface of disk, widely spaced so skin seems naked. In larger specimens, tubercles are sometimes truly absent. Except for 2 short longitudinal rows of tubercles anterior to the anal fin base, the principal tubercles occupy most of the ventral surface of tail; tubercles in skin covering bases of principal tubercles absent. Cephalic lateral-line counts: subopercular 5-6 (usually 5), preopercular, 2-3 (usually 2). Tail lateral-line counts 8-13. Fin-rays without tubercles, except sometimes a few found at the pectoral base. Pectoral fins slender. Pelvic fins with thickened skin on rays (Ref. 40826).
在側邊上的小瘤尾部有非常長的棘。 在體盤腹面上的小的小瘤, 分開很遠，如此皮膚似乎裸露。 在較大的標本中，小瘤有時真實不存在。 除了 2個短的縱列小瘤位於臀鰭基底前, 主要的小瘤佔領大部分的尾部腹面; 主要小瘤的小瘤在皮膚覆蓋的基底不存在。 頭部的側線計算: 子鰓蓋 5-6(通常 5) ，前鰓蓋骨,2-3.(通常 2) 尾部側線計算 8-13 。 除了有時一些被發現於的胸鰭基底以外,鰭條沒有小瘤。 胸鰭細長的。 在鰭條上的腹鰭有變粗的皮膚.(參考文獻 40826)
