Plots of principal component (PC) and centroid size (CS) for morphometric characters of Polypterus. a) CS and PC1 for dorsal view, b) PC1 and PC 2 for dorsal view, c) CS and PC1 for ventral view, d) PC1 and PC2 for ventral view. Grouping corresponds to the clade inferred from molecular phylogenetic analysis (Fig. 2): Blue = Polypterus ansorgei, P. bichir lapradei, P. endlicheri endlicheri, and P. e. congicus; Green = P. mokelembembe; Purple = P. ornatipinnis, P. retropinnis, and P. weeksii; Red = P. delhezi, P. palmas buettikoferi, P. p. polli, P. senegalus senegalus, and P. teugelsi.
