Note. A, Aradoidea; B, Largidae and Pyrrhocoridae; C, the remainder of Pentatomomorpha; Anthocoridae, Reduviidae, and Saldidae were used as the outgroup. La and Lb, the averages of observed numbers of substitutions per site (branch lengths) from the outgroup of two clades. Z, the parameter calculated by Phyltest [71]. The analyses were carried out under the Kimura-2-parameter distances. The asterisks mark the significantly different substitution rates (P < 0.05).
