Systematics and biogeography of the Holarctic dragonfly genus Somatochlora (Anisoptera: Corduliidae)

The Striped Emeralds (Somatochlora) are a Holartic group of medium-sized metallic green dragonflies that mainly inhabit bogs and seepages, alpine streams, lakes, channels and lowland brooks. With 42 species they are the most diverse genus within Corduliidae (Odonata: Anisoptera). Systematic, taxonomic, and biogeographic resolution within Somatochlora remains unclear, with numerous hypotheses of relatedness based on wing veins, male claspers (epiproct and paraprocts), and nymphs. Furthermore, Somatochlora borisi was recently described as a new genus (Corduliochlora) based on 17 morphological characters, but its position with respect to Somatochlora is unclear. We present a phylogenetic reconstruction of Somatochlora using Anchored Hybrid Enrichment (AHE) sequences of 40/42 Somatochlora species (including C. borisi). Our data recovers the monophyly of Somatochlora, with C. borisi recovered as sister to the remaining Somatochlora. We also recover three highly supported clades and one of mi..., Taxon Sampling
We acquired specimens of Somatochlora from natural history collections. Specimens sampled from collections in the American Museum of Natural History (AMNH), Florida State Collection of Arthropods (FSCA), Naturalis Biodiversity Center (RMNH), National Museum of Natural History Museum (NMNH), and Monte L. Bean Life Sciences Museum at Brigham Young University (BYU). In total, we sampled 40 of the 42 current species of Somatochlora. We selected a large number of outgroups to establish a robust phylogenetic placement for the Somatochlora. We sampled outgroups from Corduliidae (Hemicordulia, Procordulia, Guadalca, Paracordulia, Neurocordulia, Navicordulia, Helocordulia, Cordulia, Epitheca, Metaphya, Pentathemis, Aeschnosoma, and Antipodochlora), other established families within the superfamily Libelluloidea (Libellulidae: Pantala, Libellula, Orthetrum, Macromiidae: Macromia, Epophthalmia, Synthemistidae: Eusynthemis, Choristhemis, Gomphomacromia), and families within Cavilabia..., , # Systematics and biogeography of the Holarctic dragonfly genus Somatochlora (Anisoptera: Corduliidae): Open Source Data
