简单描述
型态特徵 | 形态测量图
背的软条 (总数): 12-13; 臀鳍软条: 10 - 11; 脊椎骨: 36 - 37. Distinguishable from the other species of the genus by having a broad dark bluish gray stripe along lateral midline of body, restricted to inner layer of tegument, overlapped by superficial dark brown spots. Also distinguished from the remaining species of the southeastern Brazil by having nine pectoral-fin rays, high number of odontodes (interopercular 59-70 vs. 30-52, opercular 23-30 vs. 10-20), anal-fin origin at vertical posterior to dorsal-fin base and a dark gray opercular patch of odontodes vs. light yellow . Differs from T. nigricans and T. immaculatus by a combination of longer nasal and maxillary barbels (nasal reaching pectoral fin base, vs. between orbit and opercular patch of odontodes; maxillary reaching anterior third of pectoral fin, vs. to interopercular patch of odontodes) and a single median third supraorbital pore vs. third supraorbital pore paired (Ref. 54465).
藉由有一个可与本属的另一个种区别宽的深蓝色的灰色斑纹沿着被局限于被表面深褐色的斑点重迭的 tegument 的内部层的身体侧面中线。 也区分巴西东南方的剩余种借着具有九个胸鳍鳍条，齿 (间鳃盖骨 59-70 vs.30-52, 鳃盖 23-30 和 10-20 比较) 的高数字, 臀鳍起源在垂直的在背鳍基底与一个齿的深灰色鳃盖小区块后面 vs. 淡黄色的。 有别于组合的 T. nigricans 与 T. immaculatus 更长的鼻与颚的触须 (鼻的被达到的胸鳍基底, vs. 在眼窩與齒的鰓蓋小區塊之間; 上頜骨達到胸鰭的前三分之一, vs. 對齒的間鰓蓋骨小區塊) 與一個中央的第三個眶上的孔和第三個眶上的孔比較成對的.(參考文獻 54465)
Although the type locality is a clear water stream with strong current, all specimens were found in still water between 50 and 200 cm deep, hidden under rocks (Ref. 54465).
虽然模式标本产地是，水流很强的地方又所有的标本被发现于在岩石下面被藏的 50 与 200 公分深之间的静止水域的清澈的水域水流。 (参考文献 54465)
