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).
10 深色的横带在身体侧边上在雄性中更明显。 在圣他安挪与 Villa Colon 附近的 Rio Virilla 的河川源头的族群是比较大而大多数的个体缺乏纵带。 在背鳍基底与鳍条上的间辐膜是墨黑色; 末梢部一半的鳍淡黄色或橘色的与边缘是黑色的雄性与雌性都有。 臀鳍是黄色或者橘黄色的而且有一个鳍的黑色斑块从基底到顶端。 腹鳍淡黄色而尾部的末梢部的边缘时常鲜黄色.(参考文献 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).
一个食虫的鱼通常居住于低到中水流速度的水域; 在 10 与 900 公尺海拔之间; 在 19 到 34 °C 的温度; 在表面或小溪，溪流的中层水域中。 偶然地发现于河的浅水域了。 (参考文献 36880)
