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); bison: The specific epithet bison refers to the enlarged nuchal hump present on large breeding males w/c is reminiscent of the body shape of the North American bison.

Espinhos dorsais (total) : 9 - 10; Raios dorsais (total) : 13 - 14; Raios anais : 7 - 8. Differs from all members of the complex in having in the breeding male the horizontal lines restricted to a series of long dark dashes, and upper sides with a zone of light tan extending the length of the body. It differs from all other species by modally having 8 anal rays and 6 scales below the lateral line (Ref. 27671).
Body shape (shape guide): elongated.
Migratory behaviour is undetermined (Ref. 126106).
