Figure 2.

Maximum parsimony trees computed from the non-ambiguous alignment portion, using original DNA data and data recoding by means of INAASE, ARC, PICS-Ord with Clustal sequence identity and PICS-Ord with Ngila zeta cost scores. The five major backbone nodes that are also supported in multigene studies are indicated by grey circles. Branches with good or strong support (70% or higher) and indicated by thick lines and branches with weak support (less than 70%) by slightly thickened lines. Exact bootstrap support values for backbone and terminal nodes are indicated in the table in the upper right corner.
