Phylogenetic concensus tree of mtDNA from Dahlica triquetrella. Post-burnin majority rule phylogenetic concensus tree of COI and COII concatenated sequences of sexual and parthenogenetic haplotypes and other Naryciinae species based on a GTR + I + G model of nucleotide substitution. Two branch support values are indicated. Left, the posterior probabilities obtained from a Bayesian analysis with partitioned sequences (four runs, each with 30.000 trees). Right, the likelihood values obtained from a Maximum Likelihood analysis with 500 bootstraps. For each haplotype, its geographic origin (see Table 1), the number of sequenced individuals, and the reproductive mode (red is sexual, white is parthenogenetic) are indicated. Note that D. fennicella is known only as parthenogenetic.# Confirmed tetraploid population .
