背棘 (总数) : 0; 背的软条 (总数) : 13; 臀棘: 0; 臀鳍软条: 9. Differs from its congeners in Indochina by the combination of the following characters: body with 7-12 regular dark bars; intestine with a wide loop, anteriorly reaching to stomach; inner rostral barbel reaching to or beyond corner of mouth; outer one clearly reaching beyond base of maxillary barbel; predorsal and dorsal part of body not darkened; predorsal bars meeting their homologues on back; a complete black bar at caudal-fin base; posterior bars not dissociated; long dorsal crests on caudal peduncle in most specimens ; pelvic fin origin below branched dorsal fin rays 1-2; lateral line complete; caudal peduncle 0.9-1.2 times longer than deep; depth of caudal peduncle 13.4-15.6% SL; median caudal-fin ray 72.1-85.7% of length of upper caudal-fin lobe; eye diameter 4.1% SL; lateral head length 102-119% HL; processus dentiformis pointed; a median incision in upper lip in most specimens (Ref. 40772).
Body shape (shape guide): elongated.
肠道有一个宽的环,前面地延伸到腹部; 内部的嘴触须延伸到或超过嘴角; 清楚地超过颚触须的基底的外部的; 身体的前背而背部部份不颜色较深; 前背的横带碰到他们的同系物背面; 在尾鳍基底的一条完全的黑色横带; 不被分离的在后部的横带; 长的背部冠在尾梗上在大多数的标本中 ; 在分枝的背鳍鳍条 1-2 之下的腹鳍起点; 侧线完整。
