Etymology: Cnesterodon: Greek, knester, -eros = scraper (Ref. 45335); pirai: The specific epithet pirai derives from the Guarani words “pirá”, meaning fish and the diminutive “í”, in allusion to the small size of the fishes belonging to the genus Cnesterodon. A noun in apposition.
Eponymy: This is not an eponym: Pirai is derived from the Guarani words that translate as ‘little fish’. (Ref. 128868), visit book page.
