Darwin Wasp Phylogenomic Data and Morphometric Landmarks for 697 Species

A phylogenomic dataset for Darwin wasps (Ichneumonidae) includes landmark configurations for head and mesosoma morphology and phylogenetic matrices. The data covers 697 species across all ichneumonid subfamilies, supporting research on evolutionary asymmetry in parasitism strategies. It was authored by Bernardo Santos and last updated on 2026-05-20.

Use Cases

• Testing hypotheses of evolutionary irreversibility (ratchets) based on transitions between parasitoid strategies like idiobiosis and koinobiosis.
• Analyzing the dynamics of host switching across holometabolous insect orders using the provided phylogenetic framework.
• Investigating the relationship between gross body shape, parasitoid strategy, and host use through geometric morphometric data.
• Reconstructing ancestral host associations, with Lepidoptera inferred as the ancestral host group.

Strengths

• Phylogenomic dataset includes 697 species, providing broad taxonomic coverage.
• Includes landmark configurations for geometric morphometric analyses of head and mesosoma shape.
• Data supports analyses across all ichneumonid subfamilies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
