title: Phylogeny of euophryine jumping spiders from ultra-conserved elements, with evidence on the intersexual coevolution of genitalia (Araneae: Salticidae: Euophryini)

description: Knowledge of phylogeny is required to understand the evolution of highly
 diverse groups such as the euophryine jumping spiders, a lineage showing
 high species and morphological diversity. In this study, we applied a
 phylogenomic approach using ultra-conserved elements (UCE) obtained from
 145 taxa to infer the phylogeny of euophryine jumping spiders. The results
 provide a well-supported phylogenetic framework for Euophryini, especially
 for the deeper relationships, in which the monophyly of Euophryini, as
 well as most clades corresponding to a genus or a group of closely related
 genera are strongly supported. Additionally, the evolutionary patterns of
 male embolus length and female copulatory duct length of 117 euophryine
 species were investigated through ancestral character state reconstruction
 and phylogenetically-independent contrasts analyses using the UCE
 phylogenetic framework. The results suggest strongly that the evolution of
 the lengths of male embolus and female copulatory duct in Euophryini is
 positively correlated. The common ancestor of Euophryini likely had
 relatively short embolus and copulatory duct, followed by repeated
 lengthening or shortening of both structures in different lineages.
 Possible mechanisms that may have caused this intersexual coevolution
 pattern in Euophryini are discussed. This study advances our
 understandings of the phylogeny, systematics and genitalic evolution of
 euophryines, providing a solid foundation for future studies on the
 diversification and evolution of this jumping spider group.

 Salticidae: Euophryini) ## Description of the data and file structure
 1_145spp_2412loci_concatenated_UCE_dataset.zip Description: Contains the
 final concatenated ultra-conserved element (UCE) dataset for 145 species
 across 2412 UCE loci for phylogenetic analyses. A partition file
 ("1_145spp_2412loci_concatenated_UCE_dataset.partition")
 corresponding to each included UCE locus is included for the model-based
 phylogenetic inference. A file containing the optimized partition scheme
 and models for the phylogenetic analyses on the concatenated dataset is
 also included
 ("1_145spp_2412_loci_optimized_partition_and_models_ML.nex").
 Note: We recommend to view these files using Notepad++.
 2_145spp_2412loci_PhylogeneticResults Description: Contains the
 phylogenetic results from the Maximum Likelihood (ML), Bayesian Inference
 (BI), and ASTRAL analyses. In the ASTRAL result, the first 100 are the
 species trees estimated from the 100 bootstrap replicates; the last one is
 the estimated species tree from the gene trees with bootstrap supports
 annotated. Note: These trees are in newick format, which could be viewed
 in Notepad++ or FigTree. 3_117spp_2412loci_AncestralReconstruction
 Description: Contains the trimmed input tree used for the ancestral state
 reconstruction analyses (based on 117 species). Note: The tree is in
 newick format, which could be viewed in Notepad++ or FigTree.
