簡短描述
型態特徵 | 形態測量圖
脊椎骨: 35 - 36. Differs from members of the genus by the following combination of characters: absence of dark stripes on body; absence of bold concentric bands on posterior part of paired fins; pelvic fin not reaching anal-fin origin; general appearance robust, body width at dorsal-fin origin 24.2-28.0% SL; caudal peduncle depth 10.7-11.2% SL; caudal peduncle length 0.8-0.9 times in its depth; predorsal body length 51.3-53.7% SL; pelvic-fin origin in front of dorsal-fin origin; absence of cavity around mouth; skin-fold between oropectoral membrane and ventral surface of head running from pectoral-fin origin to second rostral barbel; tubercles on dorsal part of head concentrated on lateral part of snout; absence of large tubercles on branched pectoral-fin rays 15-21; and 60-70 lateral line scales (Ref. 40433).
在組合特徵之後有別於本屬的成員藉由: 缺乏身體上有深色斑紋; 在偶鰭的較後面的部分上缺乏顯著的同中心的條紋; 腹鰭不達成臀鰭起源; 一般的外表結實的, 在背鰭起點 24.2-28.0% SL 的身體寬度; 尾柄深度 10.7-11.2% SL; 尾柄長度 0.8-0.9 倍它的深度; 前背的體長 51.3-53.7% SL; 在背鰭起點之前的腹鰭起點; 嘴的周圍缺乏洞; 皮膚-在 oropectoral 薄膜與從對第二的嘴觸鬚的胸鰭起源延續的頭部的腹面之間摺疊; 在頭部的背部部份上的小瘤專注於吻的側面部份了; 在分枝的胸鰭鰭條 15-21 上缺乏大的瘤結; 而且 60-70個側線鱗片.(參考文獻 40433)
