简单描述
型态特徵 | 形态测量图
背棘 (总数): 7; 背的软条 (总数): 9-10; 臀棘 1; 臀鳍软条: 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).
在组合特徵之后与本属的另一个种区分了藉由: 第二背鳍鳍条典型地 I/9; 臀鳍棘条典型地 I/8; 在纵向的系列 29-31 中的鳞片. 臀鳍起源在第三个分枝第二背鳍鳍的鳍条之下插入。 躯干通常有五或六个中央的成列暗褐色的斑块。 在后颈的较后面的部分上的一 (有时分割为二)个显着的深褐色的斑块; 斑块更大与更深色母鱼超过在雄鱼中。 颊的而且在成鱼中鳃盖有多数不规则短暗褐色的线与蠕虫爬迹形的装饰。 第二背鳍与尾鳍有大约四到五列的暗褐色的斑点。 胸鳍基底有两个或三个小的深褐色的斑点在雄鱼中的中央上但是通常二略微母鱼的垂直黑色的横带.(参考文献 38646) 与 0-3个前背的鳞片.(参考文献 43281)
Inhabits riffles with swift current among gravel and moderate pebbles.
