檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 7 - 9; 臀鰭軟條: 8 - 12; 脊椎骨: 35 - 37. Body very deep, averaging slightly less deep than N. merlini. Nuptial males with broad, lateral, bluish gray band; anterior rays of dorsal fin extend beyond posterior rays when depressed; when fresh; interadial membranes of dorsal fin almost entirely darkened with black pigment except for the orange along the base of the fin and bright yellow green on distal tips of anterior rays; caudal fins bright orange; anal fin membranes darkened with melanophores and overlaying wash of dull orange (Ref. 40813).
身體非常深的, 些微地平均得不比 N. merlini 深. 求偶的雄性有寬的﹐側面的﹐和藍灰色的條紋; 當扁平的，背鰭的前面鰭條延伸超過在後部的鰭條; 新鮮時; 背鰭的 interadial 薄膜幾乎完全顏色較深有黑色的除了橘色者在前面鰭條的末端上沿著鰭與鮮黃色的綠色的基底; 尾鰭鮮橘色的; 臀鰭薄膜以黑色素細胞顏色較深而且覆蓋洗暗橘色的.(參考文獻 40813)
