Luticola hlubikovae has higher stria density and narrowly rounded apices. Luticola saprophila is wider and the valve is more rhombic to elliptic-lanceolate. Luticola terminata differs by its rhombic to lanceolate shape, larger breadth range, broadly rounded apices, wider axial area, and the proximal raphe ends are strongly deflected. Luticola ignorata has a higher stria density, smaller breadth, and more protracted apices. Luticola grupcei is larger in length and width, has a wider length range, and has a lower stria density.
