1. Re-analysis of Outlaw et al.’s sequences

Comparing our sequences to those analyzed by Outlaw et al. we noticed that while in most intraspecific comparisons the sequences were highly similar, in few cases some regions were anomalously divergent. Using the BLAST search function in Genbank we discovered that these regions were much more similar or identical to other Muscicapidae taxa than to the putative species. Here we present the alignments of the problematic sequences with other conspecific sequences and the putative contaminants. The regions identical to the putative contaminants are highlighted. There are high chances that the following Cercomela sequences were contaminated by other samples during the lab procedures and they should be discarded.

Figure S1. Neighbour-joining tree obtained from the combination of all open-habitat chat ND2 sequences, with a selection of other Muscicapidae. The sequences obtained by us for this study are indicated in blue. The putative chimaeric sequences used by Outlaw et al. (2010) are in red.

Figure S2. Topologies obtained from the mixed-model Bayesian analysis of the concatenated mitochondrial (left) and nuclear (right) genes. The posterior probability values are indicated at the node (threshold 0.80).
