Bayesian phylogenetic tree of COI sequences based on the collected Mayaweckelia and Tuluweckelia samples and publicly available hadziid and hyalellid sequences. Hyalella azteca was included as outgroup taxon. Posterior probability values are indicated. Bahadzia jaraguensis and H. azteca sequences are after Bauza-Ribot et al. (2012) and Baird et al. (2011), respectively.
