FIGURE 6. Relative geographic distributions of species of Ptychochromis exhibiting the "eastern type palatine" configuration, including the geographically proximate sister species, P. m a k i r a and P. ernestmagnusi, new species. Note: Arrow for P. grandidieri indicates that distribution for species extends southward along the eastern coast of Madagascar.

FIGURE 8 in A new species of Ptychochromis from northeastern Madagascar (Teleostei: Cichlidae), with an updated phylogeny and revised diagnosis for the genus

FIGURE 8. Strict consensus cladogram of nine optimal topologies recovered (tree length = 1018, CI = 0.67, RI = 0.61) based on the simultaneous analysis of the nucleotide dataset of Stiassny and Sparks (2006) and 24 morphological transformations. Unambiguously optimized morphological features supporting recovered nodes are designated by solid (unique feature) and open (homoplasious feature) circles. Character numbers (above braches) and states (below branches) correspond to the morphological transformations listed in Table 2 and Appendix 1. Indices in bold at nodes indicate jackknife support. Character state descriptions and statistics are listed in Appendix 1. The morphological character matrix is presented in Table 2.

FIGURE 10. (A) Principle components (PC) 1 and 2, displaying variation in body shape for east coast Ptychochromis species. Visualization of shape variation is provided as warped grids of (B) the largest and (C) the smallest PC 1 values relative to mean shape. The largest PC 1 values are set by the shallow-bodied P. mainty and the smallest by the deep-bodied P. curvidens. Fixed landmarks are shown in gray and sliding semilandmarks are in black.
