背棘 (总数) : 1; 背的软条 (总数) : 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).
Body shape (shape guide): elongated; Cross section: compressed.
在尾鳍基底的中央上的半圆的斑点,大约等于眼直径; 深色的斑点经过第五个分枝的背鳍鳍条越过第二个的基底延伸。 臀鳍有 4-5 单一的鳍条, 8-9个分支条, 总 12-14个鳍条。 眼相当大的, 它的直径大约等于吻的长度。 鼻骨触须越过眼窝的后缘正好延伸; 上颌骨触须有宽的薄膜, 触须达成臀鳍起源。 (参考文献 40780)
