Global DNA Barcode Reference Library for Solenogastres Molluscs

655 newly generated DNA sequences combined with previously published data form a reference library for Solenogastres, a group of shell-less marine molluscs. The dataset includes 531 COI, 483 16S, and 129 CytB barcodes representing an estimated 325 species from 642 specimens. It was created by Emily L. McLaughlin and made available on figshare in May 2026.

Use Cases

• Species identification and delimitation based on DNA barcode sequences.
• Phylogenetic analysis to resolve taxonomic relationships within Solenogastres.
• Assessing marine biodiversity and species distributions using genetic reference data.
• Training or benchmarking DNA barcode classification models for marine invertebrates.

Strengths

• Integrates 655 new sequences with prior data for a total of 1143 barcodes.
• Represents an estimated 287 solenogaster species from 642 specimens.
• Specimen identification was verified using an integrative approach combining molecular data with histology and microscopy.
• Phylogenetic analysis recovers major clades consistent with prior transcriptome-based studies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or collection bias inherent to the source specimens.
