Figure 1. The phylogenetic relation between the wood-eating cockroach Cryptocercus species and the primitive termite M. darwiniensis as well as the interfamilial relations within Blattodea inferred from BI and ML analyses based on amino acid sequences derived from the 13 mitochondrial PCGs. Only the BI tree is shown. The numbers at the nodes indicate bootstrap values of BI (above diagonal) and ML (below diagonal).
