簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 14 - 19; 臀鰭軟條: 17 - 19; 脊椎骨: 26 - 27. Differs from all other species of the subgenus Simpsonichthys by having longitudinal rows of light blue dots on flank in males (vs. absence) and a long filamentous ray on tip of dorsal fin in males, reaching the posterior position of caudal fin (vs. reaching basal portion of caudal fin). Can be differentiated from all congeners by the unique combination of the following characters: pelvic fin present (vs. absent), second pharyngobranchial teeth absent (vs. present), ventral process of posttemporal short (vs. long), 18-19 dorsal-fin rays in males and 14-15 in females (vs. 15-17 in males, 12-13 in females), long filamentous ray on tip of dorsal fin males (vs. filamentous rays short or absent), five alternating bright blue and pink to red bars on head side in males (vs. never a similar color pattern), pectoral fin pink with blue spots in males (vs. hyaline), and absence of black spots on dorsal fin in males (vs. presence of black spots on basal portion of dorsal fin). Caudal fin round (Ref. 58746).
有別於所有的其他種的亞屬 Simpsonichthys 在被達到尾鰭的後面的位置的雄性中的背鰭的頂端上的雄性 (vs. 缺乏) 與一個長的絲狀鰭條中的側面上藉著具有縱列的淺藍色點.(vs. 達到尾鰭的基部部分) 能從所有同類被下列特徵的組合區別: 有腹鰭 (vs. 不存在), 第二的咽鰓骨齒不存在 (vs. 存在的), 腹突起後顳骨短 (vs. 長的), 18-19 背鰭鰭條在雄性與 14-15 在雌性 (vs.15-17 在雄性中, 12-13 在雌性中), 長的絲狀鰭條頂端之上背鰭雄性 (vs. 絲狀的鰭條短或者不存在), 五交互的淡藍色與粉紅色到紅色橫帶頭部側邊之上在雄性 (vs. 從不一個相似的彩色斑紋), 胸鰭粉紅色有藍色的斑點在雄性 (vs. 透明的), 而且缺乏黑色的斑點背鰭之上在雄性 (vs. 有黑色的斑點在背鰭的基部部分上). 尾鰭圓.(參考文獻 58746)
