Tree of Cettiidae based on concatenated sequences, with single-locus analyses superimposed - all species, partitioned analysis. Majority rule (50%) consensus tree, based on concatenated nuclear ODC, myoglobin and GAPDH and mitochondrial cytochrome b, inferred by Bayesian inference (BI), analysed in four partitions. All species, but only a small number of subspecies, were included. Generic affinity according to traditional taxonomy  is indicated by different colour shadings. The three species for which only cytochrome b (C) is available, and the single species for which only ODC (O) and GAPDH (G) are available, are in red. Posterior probabilities are indicated at the nodes; an asterisk represents posterior probability 1.00. The outgroups (Alauda arvensis and Mirafra javanica in Alaudidae and Orthotomus sepium, O. sutorius and Prinia familiaris in Cisticolidae) have been pruned from the tree. Pie charts at nodes denote support in single-locus analyses (see explanation in upper left corner; see also Additional files 1, 2, 3 and 4).
