28S rDNA tree. Maximum likelihood tree of the genus Bryobia and four outgroup species of the genus Petrobia for the nuclear rDNA 28S D1 region. For each haplotype (branch tip) samples sharing that haplotype are given (see Additional file 1 and 2 for abbreviations and sample details). Clades are colored according to their host plant association (see legend at the bottom). Clades are followed by the mode of reproduction (A = asexual, S = sexual) and presumed species name. Numbers above branches indicate the percentage bootstrap values based on 1,000 replicates, numbers below branches depict Bayesian posterior probabilities (only values larger than 50 (ML) and 0.50 (Bayesian) are indicated). The bar at the bottom indicates a branch length of 10% likelihood distance.
