Maximum Likelihood tree/Bayesian Inference tree constructed by 13 PCGs. The trees built by ML (See Supplementary Fig. 3, Additional file 2) and BI (See Supplementary Fig. 4, Additional file 2) have been combined. The numbers at the internodes are maximum likelihood bootstrap proportions and bayesian inference posterior proportions. The branch lengths have been ignored to make the tree more orderly. The newly sequenced species are marked with the star after the species name. For A. gracilipedum: A (ON000286); B (OP526650); C (MZ350905)
