A cladogram of the species tree with the consensus trees based on the combined mtDNA and nuDNA is visualized on the left. The results of multiple species delineation analysis (ASAP, bPTP, mPTP, structure, morphometry (including PCA and vertebral count) and geography are shown on the right. Colored bars represent the six clades (or putative species) of the LCC. Grey rectangles with the number “1” mean that two taxa should be collapsed into one
