Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 8 - 11; Raios dorsais moles (total) : 11 - 15; Espinhos anais: 0; Raios anais moles: 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).
Body shape (shape guide): elongated.
Greatest abundance is attained in small (1-2 m wide) to medium (3-5 m wide) upland gravel and cobble streams where they are 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). Migratory behaviour is undetermined (Ref. 126106).
