Fig. 2. Strict consensus of nine equally most-parsimonious trees (length 1014, CI 5 0.67, RI 5 0.61) recovered, based on the simultaneous analysis of 2029 aligned mitochondrial and nuclear nucleotide characters and 21 morphological transformations. Unambiguously optimized morphological features supporting recovered nodes are designated by solid (unique feature) and open (homoplasious feature) circles. Character numbers and states correspond to the morphological transformations listed in table 1. Support indices at nodes are presented in parenthesis (Jackknife/Bremer support).
