簡短描述
型態特徵 | 形態測量圖
Body and head grayish with fine black line along midside and a black blotch on the anal fin. Tail with a black oval blotch on its base (lacking in some individuals found in Río San Juan). Snout sharp and pointed. Anal fin shorter than head length. B. cascajalensis differs from this species in the absence of the black blotch on the base of the tail (mitochondrial DNA implies that the two are valid) (Ref. 36880).
身體與頭部淺灰色的有細黑色的線在臀鰭上沿著側面中央與一個黑色的斑塊。 尾部有黑色的橢圓形的斑塊在它的基底。 (沒有一些個體發現於聖幻河了) 吻部尖而尖的。 臀鰭短於頭長。 B. cascajalensis 有別於這種在那在尾部 (線粒體 DNA 暗示，兩者是有效種) 的基底上缺乏黑色的斑塊.(參考文獻 36880)
Lives in current of low to moderate velocity between 5-50 m of elevation; at temperatures of 23-34°C. Found near the surface along large river banks, but not common in streams. Feeds on terrestrial insects and in small quantity on aquatic insects. Reproduces throughout the year (Ref. 36880).
生活在 5- 之間的低到中速度的水流海拔的 50 公尺; 在 23-34個 ° C. 的溫度 沿著大的河岸發現於靠近表面了, 但是不常見於溪流。 吃陸棲的昆蟲與在小的量吃水生昆蟲中。 繁殖全年度。 (參考文獻 36880)
