簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 7; 脊椎骨: 35 - 36. Semicircular spot on the middle of caudal-fin base, about equal to eye diameter; dark spot extending across bases of second through fifth branched dorsal-fin rays. Anal fin with 4-5 simple rays, 8-9 branched rays, total 12-14 rays. Eye relatively large, its diameter about equal to snout length. Nasal barbel extends just past posterior margin of orbit; maxillary barbel with broad membrane, barbel reaches anal-fin origin (Ref. 40780).
在尾鰭基底的中央上的半圓的斑點,大約等於眼直徑; 深色的斑點經過第五個分枝的背鰭鰭條越過第二個的基底延伸。 臀鰭有 4-5 單一的鰭條， 8-9個分支條, 總 12-14個鰭條。 眼相當大的, 它的直徑大約等於吻的長度。 鼻骨觸鬚越過眼窩的後緣正好延伸; 上頜骨觸鬚有寬的薄膜, 觸鬚達成臀鰭起源。 (參考文獻 40780)
