Sandall 2020 Dissertation Supplementary Appendix D

The snaketail dragonflies are a genus of 29 species of medium-sized dragonflies in the Gomphidae family. With a distribution that spans Nearctic, Oriental, and Palearctic regions, peak species diversity is in North America. Though many species have been described since the genus was erected in the mid-1800s, the majority of phylogenetic relationships for both New and Old World taxa have never been formally tested. We use Bayesian and maximum likelihood analyses on morphological data of adults and larvae, molecular data, and a total evidence dataset to evaluate the phylogenetic relationships between species of Ophiogomphus. Our molecular data suggests that the snaketail radiation took place primarily in the Nearctic and that the Palearctic species are monophyletic. We found that the larval morphology particularly aids in clarifying relationships in clades with poor resolution. These two findings suggest a need for the genus Ophiogomphus to be analyzed through additional specimen access and possibly revised to more accurately account for these relationships.
