簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 7; 背的軟條 (總數) : 9 - 10; 臀棘: 1; 臀鰭軟條: 8 - 10; 脊椎骨: 28. Distinguished from the other species of the genus by the following combination of characters: 2nd dorsal fin rays modally I/9; anal fin rays modally I/8; scales in longitudinal series 29-31. Anal fin origin inserted below third branched ray of second dorsal fin. Trunk usually with five or six middle series of blackish brown blotches. One (sometimes split into two) conspicuous brownish black blotch on posterior part of nape; blotch larger and darker in female than in male. Cheek and opercle with many irregularly short blackish brown lines and vermiculations in adult. Second dorsal and caudal fins with about four to five rows of blackish brown spots. Pectoral fin base with two or three small dark brown spots on the middle in male but usually two somewhat vertical black bars in female (Ref. 38646). With 0-3 predorsal scales (Ref. 43281).
Body shape (shape guide): elongated.
在組合特徵之後與本屬的另一個種區分了藉由: 第二背鰭鰭條典型地 I/9; 臀鰭棘條典型地 I/8; 在縱向的系列 29-31 中的鱗片. 臀鰭起源在第三個分枝第二背鰭鰭的鰭條之下插入。 軀幹通常有五或六個中央的成列暗褐色的斑塊。 在後頸的較後面的部分上的一 (有時分割為二)個顯著的深褐色的斑塊; 斑塊更大與更深色母魚超過在雄魚中。 頰的而且在成魚中鰓蓋有多數不規則短暗褐色的線與蠕蟲爬跡形的裝飾。 第二背鰭與尾鰭有大約四到五列的暗褐色的斑點。 胸鰭基底有兩個或三個小的深褐色的斑點在雄魚中的中央上但是通常二略微母魚的垂直黑色的橫帶.(參考文獻 38646) 與 0-3個前背的鱗片.(參考文獻 43281)
Inhabits riffles with swift current among gravel and moderate pebbles.
棲息於在礫石與中等的小圓石之中的水流湍急的急流。
