Mygalomorph Spider Phylogeny with rRNA and EF-1γ Genes

Phylogenetic data for the infraorder Mygalomorphae includes 15 families and 58 genera. The dataset combines rRNA genes 18S and 28S, the nuclear protein-coding gene EF-1γ, and a morphological character matrix to reevaluate spider classification. It was produced by Jason E. Bond and published in 2020.

Use Cases

• Reconstruct phylogenetic trees using the combined 18S, 28S, and EF-1γ gene sequences and morphological character matrix.
• Test the monophyly of families like Mecicobothriidae and Cyrtaucheniidae based on the genetic and morphological data.
• Evaluate the proposed establishment of the family Euctenizidae and the subfamily Apomastinae using the provided phylogenetic analyses.
• Analyze taxon sampling across 58 genera to identify gaps for future systematic studies of Mygalomorphae.

Strengths

• Taxon sampling includes members of all 15 recognized families within the infraorder Mygalomorphae.
• Data combines three nuclear genes (18S, 28S, EF-1γ) with a morphological character matrix for a multi-evidence approach.
• Analysis led to specific nomenclatural proposals, including the establishment of a new family rank (Euctenizidae).

Limitations

• The dataset's scope is taxonomic and phylogenetic, lacking typical tabular structure with rows and columns for direct statistical analysis.
• Sample size is limited to 58 genera, representing a fraction of the over 2,600 described species in the infraorder.
• Data is static from a 2020 publication and may not reflect subsequent taxonomic revisions or discoveries.
