<abstract language="eng">Odontesthes mirinensis, a new species of silverside, is described in coastal lagoons system of Rio Grande do Sul, Brazil. The new species is distinguished from other Odontesthes species by short snout and having 24-29 gill rakers on the lower branch of the first branchial arch. Osteological features (bones of the skull, axial skeleton and girdles) are included and discussed. Meristic and morphometric variables were analyzed separately, through multivariate procedures. Principal Component Analysis show that Odontesthes mirinensis, sp.n. does not exhibit significant geographic variation on body shape
