Figure 1

Seven contours digitized on the wing for outline-based geometric morphometric analysis. Cell 0, the external contour of the wing; Cell 1, between veins R2 and R3; Cell 2, delimited by veins R2+3, R3 and R4+5 and rm; Cell 3: delimited by veins R4+5, M1, M1+2 and rm; Cell 4, between veins M1 and M2; Cell 5, delimited by veins M1+2, M2 and M3+4; Cell 6 between M3+4 CuA and mcu. The nomenclature of veins follows Rattaranaritikul et al. 2010 (p. 71). The arrow shows the small part of the external contour which was artificially joined to obtain a completely close outline.
