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); etnieri: Named after David A. Etnier (Ref. 10294).
Eponymy: Dr David A Etnier (d: 1937) is Emeritus Professor of Zoology at the University of Tennessee which houses the ‘Etnier Ichthyological Collection’ of over 40,000 specimens that he began (1960s). [...] (Ref. 128868), visit book page.
