Fig. 2

Morphospace of all 35 specimens constructed using the entire landmark and semilandmark dataset. Extreme shapes representing the positive and negative extremes along PC1 and PC2 are displayed, which are created by mirroring the landmark and semilandmark data and warping these data along PC1 and PC2. For a morphospace of PC1-PC3, see Additional file 1: Figure S7. For extreme shapes for PC1, PC2 and PC3 in dorsal, ventral, lateral, anterior and posterior aspects see Additional file 1: Figure S4–S6
