简单描述
型态特徵 | 形态测量图
背的软条 (总数): 10. Distinguished from all congeners by the following combination of characters: 15-20 branched anal-fin rays; four or five scales in transverse series from the dorsal-fin origin to the lateral line; shallow body (depth 23.6-30.6% of SL); 37-43 perforated lateral line scales; first, third and fifth or, more rarely, first and fourth outer premaxillary tricuspid teeth projecting anteroventrally; two to five tricuspid to pentacuspid maxillary teeth, followed by five to seven smaller conical to tricuspid teeth; conspicuous dark, vertically elongated humeral spot, extending to below the lateral line; dark dorsal stripe extending from supra-occipital spine to the caudal peduncle with a gap at the adipose-fin base; caudal-fin lobes without conspicuous markings, uniformly pigmented along rays; no hooks on the pelvic and anal-fin rays in mature males (Ref. 54761).
与所有的同类区分了藉由跟随组合特征: 15-20 分枝臀鳍棘条; 在来自背鳍起源到侧线的横跨的系列中的四或五个鳞片; 浅的身体;(深度 23.6-30.6% 的 SL) 37-43个穿孔的侧线鳞片; 第一个, 第三与第五的或, 更很少, 第一个与第四个外部的上颌骨前的三尖齿突出的前腹部地; 对 pentacuspid 上颚齿的二到五个三尖瓣, 跟随着了五到七比较小的锥形对三尖齿; 显著的深色, 垂直地延长了肩部的斑点, 延伸至侧线下面; 从后头骨上方的棘到尾梗延伸的深色背部的斑纹在脂鳍基底具有一个间隙;沒有顯著的斑紋的尾鰭葉, 均勻地有顏色沿著鰭條; 在成熟的雄性中的沒有在腹鰭與臀鰭鰭條上的鉤.(參考文獻 54761)
描述: 背鰭鰭條 ii, 8, 很少地 ii, 7 或 9. 胸鰭鰭條 i ， 10-13. 腹鰭鰭條 i, 7, 很少地 i, 6 或 8. 臀鰭棘條 ii-iii ， 15-20.(參考文獻 54761)
Found in Ribeirão Santa Barbara, the type locality, which has two distinct reaches: a lentic pool which is 23-49 m wide, 1.5 m deep, with a water velocity of 0.4 m/s, over a gravel bottom and some smaller areas with sand or mud; and a rapid located further upstream, which is 6.2-13.5 m wide, 0.5 m deep, with a greater water velocity of 1.1 m/s and a rocky bottom. Both stretches have margins with altered riparian forest or herbaceous vegetation (Ref. 54761).
发现于 Ribeirao 圣芭芭拉，模式标本产地了, 有二明显的范围: 一个静水的水池是 23-49 公尺宽 , 1.5 公尺深, 具有一个 0.4个公尺/秒的水速度, 遍及一个砾石底部与一些较小的区域以沙或泥; 而且一迅速的位于进一步的向上游, 是 6.2-13.5 公尺宽 , 0.5 公尺深, 具有一个 1.1个公尺/秒与一个岩石的底部较大的水速度。 两者的支流边缘有改变河岸的森林或草本的植物。 (参考文献 54761)
