簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 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).
在組合特徵之後與所有的同類區分了藉由: 15-20 分枝臀鰭棘條; 在來自背鰭起源到側線的橫跨的系列中的四或五個鱗片; 淺的身體;(深度 23.6-30.6% 的 SL) 37-43個穿孔的側線鱗片; 第一個, 第三與第五的或, 更很少, 第一個與第四個外部的上頜骨前的三尖齒突出的前腹部地; 對 pentacuspid 上顎齒的二到五個三尖瓣, 跟隨著了五到七比較小的錐形對三尖齒; 顯著的深色, 垂直地延長了肩部的斑點, 延伸至側線下面; 從後頭骨上方的棘到尾梗延伸的深色背部的斑紋在脂鰭基底具有一個間隙; 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).
發現於 Ribeirao 聖芭芭拉，模式標本產地了, 有二明顯的範圍: 一個靜水的水池是 23-49 公尺寬 , 1.5 公尺深, 具有一個 0.4個公尺/秒的水速度, 遍及一個礫石底部與一些較小的區域以沙或泥; 而且一迅速的向上游位於進一步, 是 6.2-13.5 公尺寬 , 0.5 公尺深, 具有一個 1.1個公尺/秒與一個岩石的底部較大的水速度。 兩者的支流邊緣有改變河岸的森林或草本的植物。 (參考文獻 54761)
