FIGURE 4. Fabaeformiscandona valve outlines in lateral view, showing comparative methods for measuring the inclination of the upper (Up) and the lower (Do) segments of the posterior margin of the outline. A, B, F. balatonica; C, D, F. levanderi. A, C = Method 1, using the lines of the segments between the control points d2 and m1 (red line for Up) and the control points m1 and v11 (green line for Do), with angles measured relative to the X-axis of inertia. B, D = Method 2 using visual approximation of the Up (red line) and Do (green line) segments of the posterior margin, with angles measured relative to the horizontal line defined by the two convexities of the ventral margin.
