Figure 30. Cluster dendrogram for the Euclidian distance in wing morphometry PCA for the Gracilopsina and Madagopsina species using the complete clustering method. Branch labels give the approximately unbiased p - value (AU) and bootstrap probability (BP) values (%).

Figure 31. Eye span plotted against body length for the three species in the Madagopsina apollo species group: M. apollo, M. parvapollina and M. makayensis Feijen, Feijen & Feijen, sp. nov. Note the position of the single data point for the ♂ of the latter species, in line with the ♂ data points for M. parvapollina.
