Target enrichment sequence data of Odonata, supporting Bybee et al. 2021

Dragonflies and damselflies are a charismatic, medium-sized insect order
(~6300 species) with a unique potential to approach comparative research
questions. Their taxonomy and many ecological traits for a large fraction
of extant species are relatively well understood. However, until now, the
lack of a large-scale phylogeny based on high throughput data with the
potential to connect both perspectives has precluded comparative
evolutionary questions for these insects. Here, we provide an ordinal
hypothesis of classification based on anchored hybrid enrichment using a
total of 136 species representing 46 of the 48 families or incertae sedis,
and a total of 478 target loci. Our analyses recovered the monophyly for
all three suborders: Anisoptera, Anisozygoptera and Zygoptera. Although
the backbone of the topology was reinforced and showed the highest support
values to date, our genomic data was unable to fully resolve portions of
the topology. The latter suggests that increasing the taxon sampling might
resolve these issues rather than increasing molecular data. In addition, a
quartet sampling approach highlights the potential evolutionary scenarios
that may have shaped evolutionary phylogeny (e.g., incomplete lineage
sorting and introgression) in the evolutionary history of this taxon.
Finally, in light of our phylogenomic reconstruction and previous
morphological and molecular information we proposed an updated odonate
classification and define five new families (Amanipodagrionidae fam. nov.,
Mesagrionidae fam. nov., Mesopodagrionidae fam. nov., Priscagrionidae fam.
nov., Protolestidae fam. nov.)  and reinstate another two
(Rhipidolestidae stat. res., Tatocnemididae stat. res.). Additionally, we
feature the problematic taxonomic groupings for examination in future
studies to improve our current phylogenetic hypothesis.
