Compare Navicula goersii
Compare
Species of Hippodonta have more strongly silicified frustules, broader profiles in girdle view, and simpler external raphe systems that lack the hooked or strongly deflected terminal fissures characteristic of Navicula species. Navicula goersii is distinguished from N. perminuta by its subrostrate rather than obtusely rounded ends. It differs from N. exilis by its smaller size, coarser striation, and rectangular shape of the central area. It differs from N. veneta by its smaller size, subrostrate ends, and distinctly transverse central area. Compared to N. nanissima, N. goersii has coarser striation, a larger central area, broader ends, and a less abrupt transition from radiate to parallel striae toward the apices.
