FIGURE 4. Principal components analysis of sand flies head. Head geometric morphometry analyzes showing the projection of the specimens of Chagasi Series on the principal components 1 and 2 and the shape variation display by each component. A. Specimens distribution in principal component 1 and 2. B. Principal component 1; C. Principal component 2. Light blue line = most negative points, dark blue line = most positive points.
