Regression of first discriminant factor on centroid size by altitude groups in June for females (a, b) and males, (c, d). Horizontal axis: centroid size of the wing. Vertical axis: discriminant factor 1 (a, c) or discriminant factor 2 (b, d). The regression was based on the partial warps. Regression line is shown. Squares indicate individual sand flies. Altitude groups: 1 (200–300 m), 2 (300–400 m), 3 (400–500 m), 4 (> 500)
