Phylogenetic relationship of Costalampys gen. nov. found in the consensus of the two most parsimonious trees found on the Equal Weights parsimony analysis. Above and below branches, the absolute Bremer and bootstrap (if >50) supports, respectively. Black arrow points to the node of the Costalampys gen. nov. clade.

Phylogenetic relationship of Costalampys gen. nov. found in the consensus of the four most parsimonious trees found on the Equal Weights parsimony analysis. Synapomorphies that are not homoplastic are marked with black circles, while homoplastics ones are marked with empty circles.

Phylogenetic relationship of Costalampys gen. nov. found in the IW parsimony analysis (K= 1, 2, 3 and 5). Above the branches are marked the symmetric resampling values (<50).

Phylogenetic relationship of Costalampys gen. nov. found in the Implied Weights parsimony analysis (K= 1, 2, 3 and 5). Synapomorphies that are not homoplastic are marked with black circles, while homoplastics ones are marked with empty circles.
