Distinguished by the unique color pattern on the flank in males, with red marks variable in shape, highly overlapped (vs. never a similar color pattern), and caudal fn with dark gray stripe posterior to caudal spot in females (vs. stripe absent). Also distinguished from all other members of the R. punctatus group by the combination of the following features: frontal squamation F-patterned (vs. E-patterned), flank with striking iridescent colors in male, contrasting metallic blue to greenish blue on middle of flank with light purplish blue above anal fin and brownish golden on anterior dorsolateralportion of body (vs. never a similar color pattern), no distinctive dark stripe along midline of flank (vs. stripe present); red bars on caudal fin in males (vs. bars absent).
与所有的区分了其他种的 R. punctatus 在雄性中的侧面上聚集藉由独特的彩色斑纹, 有红色的标志可变的在外形上, 高度地重迭 ( 和 比较从不一个相似的彩色斑纹), 与尾部的 fn 用深灰色斑纹在雌性中在尾部的斑点后面.( 和 斑纹比较不存在) 也区分 R. punctatus 的所有其他成员聚集藉由下列特征的组合: 前的鳞片排列 F-式样 ( 和 电子比较式样), 侧面具有显著的在雄鱼中的彩虹色的颜色, 对比铁蓝色的到藍綠色的在側面的中央上有淡色的帶紫色的藍色上方臀鰭與褐色的金在前面身體 ( 和 比較從不一個相似的彩色斑紋) 的 dorsolateralportion, 沒有特殊的深色斑紋沿著側面的中線;( 和 斑紋比較存在的) 在雄性中的在尾鰭上的紅色的橫帶.( 和 橫帶比較不存在)
