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.

Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 8 - 11; Mjukstrålar i ryggfenan (totalt) : 11 - 15; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 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).
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).
