Schematic phylogeny of the spider mites.

Except for Eo. uchidai, each operational taxonomic unit (OTU) is indicated by a symbol corresponding to Figs 1 and 2 (A-F and a1-a4). White dots indicate nodes that are not supported by bootstrap values of 100% or posterior probabilities of 1.0. a) Maximum likelihood (ML) tree based on the nucleotide sequences (Fig 1, 652 genes, total alignment length = 790,047 bases). b) ML tree based on the amino acid sequences (Fig 2, 652 genes, total alignment length = 264,133 amino acid residues). c) ML tree of the 18S and 28S rRNA genes [3]. Branch with the dotted gray line indicates that Eotetranychus species and Sc. cercidiphylli in this branch was not monophyletic but paraphyletic. d) Bayesian tree of the 18S and 28S rRNA genes [3].
