For each gene region, the number of species analyzed, the aligned length of the gene region, the number of variable characters, the number of unique sequences with gaps treated as missing data (number with gaps treated as a fifth state), and the maximum number of species that can be identified by the data (Max ID rate = Identical sequences/total number of species) are reported. Also provided are summary statistics of genetic distances using a Kimura 2-parameter (K2P) model and include: maximum genetic distance (max), mean interspecific distance (mean) with standard deviation (SD), and the proportion of comparisons of genetic distances greater than 1% (>1%) and greater than 2% (>2%). See Additional file 1 for details on species sampling.
