簡短描述
型態特徵 | 形態測量圖
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).
與所有的區分了其他種的 R. punctatus 在雄性中的側面上聚集藉由獨特的彩色斑紋, 有紅色的標誌可變的在外形上, 高度地重疊 ( 和 比較從不一個相似的彩色斑紋), 與尾部的 fn 用深灰色斑紋在雌性中在尾部的斑點後面.( 和 斑紋比較不存在) 也區分 R. punctatus 的所有其他成員聚集藉由下列特徵的組合: 前的鱗片排列 F-式樣 ( 和 電子比較式樣), 側面具有顯著的彩虹色的顏色在雄魚中, 對比鐵藍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)
