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); striatulum: striatulum refers to the striated appearance due to faint dark horizontal lines along the sides (Ref. 10294).
