The 10 dark bars on the sides of the body are more pronounced in males. The population in the headwaters of Río Virilla near Santa Ana and Villa Colón are larger and most individuals lack the vertical bars. Interradial membranes on the base of the dorsal fin and the rays are jet black; distal half of the fin yellowish or orange and the margin is black in both sexes. Anal fin is yellow or yellow-orange and has a black blotch from the base to the tip of the fin. Pelvic fins yellowish and caudal distal margin often brilliant yellow (Ref. 36880).
Body shape (shape guide): elongated; Cross section: oval.
10 深色的橫帶在身體側邊上在雄性中更明顯。 在聖他安挪與 Villa Colon 附近的 Rio Virilla 的河川源頭的族群是比較大而大多數的個體缺乏縱帶。 在背鰭基底與鰭條上的間輻膜是墨黑色; 末梢部一半的鰭淡黃色或橘色的與邊緣是黑色的雄性與雌性都有。 臀鰭是黃色或者橘黃色的而且有一個鰭的黑色斑塊從基底到頂端。 腹鰭淡黃色而尾部的末梢部的邊緣時常鮮黃色.(參考文獻 36880)
An insectivorous fish generally inhabits waters of low to moderate current velocity; between 10 and 900 m elevation; at temperatures of 19 to 34°C; in surface or midwaters of brooks, streams. Occasionally found in shallow waters of rivers (Ref. 36880).
一個食蟲的魚通常居住於低到中水流速度的水域; 在 10 與 900 公尺海拔之間; 在 19 到 34 °C 的溫度; 在表面或小溪，溪流的中層水域中。 偶然地發現於河的淺水域了。 (參考文獻 36880)
