Data from: Phylogenomic data reveal three new families of poorly studied Solifugae (camel spiders)

The systematics of the arachnid order Solifugae have been an enigma, owing
to challenges in interpreting morphology, a paucity of molecular
phylogenetic studies sampling across the group, and a dearth of taxonomic
attention for many lineages. Recent work has suggested that solifuge
families largely exhibit contiguous distributions and reflect patterns of
vicariance, with the exception of three families: Melanoblossidae,
Daesiidae and Gylippidae. Morphological studies have cast doubt on their
existing circumscriptions and the present composition of these taxa
renders their distributions as disjunct. We leveraged ultraconserved
elements (UCEs) to test the phylogenetic placement of three key lineages
of Solifugae that cause these anomalous distributions: Dinorhax
rostrumpsittaci (putative
melanoblossid), Namibesia (putative daesiid),
and Trichotoma (putative gylippid). Phylogenetic
placement of these three genera based on UCEs rendered the families that
harbor them as para- or polyphyletic, recovering instead relationships
that better accord with a biogeographic history driven by vicariance.
Toward a stable and phylogenetically informed classification of Solifugae,
we establish three new families, Dinorhaxidae new rank,
Namibesiidae new rank and Lipophagidae new
rank.
