背棘 (总数) : 8 - 11; 背的软条 (总数) : 11 - 15; 臀棘: 0; 臀鳍软条: 6 - 9. Differs from all members of the Etheostoma spectabile complex except E. tecumsehi in having orange belly color confluent with the anterior orange interspaces in breeding males and in having the alternating orange and blue transverse bars prominent along the entire length of the body (versus limited to posterior half) (Ref. 47261).
有别于除了 E. tecumsehi 以外的 橙胸镖鲈［Etheostoma spectabile］ 复合体的所有成员有 , 橘色的腹面颜色与在繁殖期的雄性中的前面橘色的间隙汇合而且有交互的橘色而蓝色的横跨横带突出的沿着整个的体长 (对仅限于的后半段).(参考文献 47261)
Attains its greatest abundance in small (1-2 m wide) to medium (3-5 m wide) upland gravel and cobble streams where it is found mainly in moderately-flowing to swift shallow riffles and runs (Ref. 47261). Adults and juveniles are encountered in pools over gravel and bedrock but not as common there unless the pool is in or near a spring (Ref. 47261).
达到它最大的丰度在小的 (1-2 公尺宽) 对中等的 (3-5 公尺宽) 丘陵地砾石与圆石溪流在哪里它被主要发现于水流速度中等到迅急的水浅急流与小水流.(参考文献 47261) 成鱼与稚鱼在砾石与岩床上的水池被见到但是不当普遍在哪里除非水池在泉水里或附近.(参考文献 47261)
