簡短描述
檢索表 | 型態特徵 | 形態測量圖
Distinguished from all other species of the R. punctatus group in having an anal fin with an orange distal stripe (vs. orange distal stripe absent) and caudal fin with marginalregion dark orange with black ventral outline in males (vs. never a similar pattern). Differs from all other species from the Paraná-Paraguay basin by the combination of the following features: flank with chevron-like red lines (vs.oblique rows of red dots), flank with dark gray stripe along midline (vs. strike absent), and 34-35 scales on the longitudinal series (vs. 30-32 as in all other species of the rio Paraguay basin).
與所有的區分了其他種的 R. punctatus 在有一個臀鰭有一條橘色的末梢部的斑紋 ( 和 比較橘色的末梢部的斑紋不存在) 方面聚集而且尾鰭有 marginalregion 深色的橘色有黑色的腹面雄性的邊緣.( 和 比較從不一個相似的圖案) 有別於所有的其他種從 Parana-巴拉圭的流域藉由下列特徵的組合: 具有像鋸齒形一樣的紅色線 ( 和 比較列斜的紅色點) 的側面, 側面用深灰色斑紋在縱向的系列上沿著中線 ( 和 攻擊比較不存在), 與 34-35個鱗片.( 和 30-32 比較當在所有的其他種的 rio 巴拉圭流域)
