Phylogenetic trees of the mitochondrial sequence data, including sequences taken from GenBank. The trees were created using maximum likelihood, and node support values (for those > 500) are based on 1000 bootstrap replicates. Each sequence is shown with its GenBank accession number, followed by the haplotype code (for our sequences) or the species name (as per the GenBank accession information, as of August 28, 2012). If a geographical location was given as part of the GenBank accession information, it is also included, in brackets. Each of the Mendoza sequences we produced for this paper is identified with a red dot. Pseudosuccinea columella was used as the outgroup. A: COI data. B: 16S data.
