Etymology: Etheostoma: Greek, etheo = to strain + Greek, stoma = mouth; Rafinesque said "various mouths", but Jordan and Evermann suggest the name might have been intended as "Heterostoma (Ref. 45335); lawrencei: Named after Lawrence M. Page.
Eponymy: Professor Dr Lawrence ‘Larry’ Merle Page (d: 1944) (see Page) (Ref. 128868), visit book page.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 8 - 11; Raggi dorsali molli (totale) : 11 - 15; Spine anali: 0; Raggi anali molli: 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).
