Data from: Discovery of an endemism hotspot of freshwater mussels (Bivalvia: Unionidae) in Assam, with a description of two new genera

This data supplements our article "Discovery of an endemism hotspot of freshwater mussels (Bivalvia: Unionidae) in Assam, with a description of two new genera" (Zoological Journal of the Linnean Society, 2024; doi: 10.1093/zoolinnean/zlae052) and contains 11 files, described below.<b>Supplementary Datasets</b>:<b>Dataset S1.</b> Information on new samples and DNA sequences of freshwater mussels from Assam [separate XLSX file].<b>Dataset S2.</b> Information on DNA sequences of freshwater mussels (Unionidae) used to reconstruct multi-locus phylogenies (one or two haplotypes per species) [separate XLSX file].<b>Dataset S3.</b> Reference DNA sequence library for correct molecular identification of freshwater mussels of the subfamily Parreysiinae from South and Southeast Asia (one or two haplotypes per species) [separate XLSX file].<b>Dataset S4.</b> Reference <i>COI</i> sequences for correct molecular identification of freshwater mussels of the subfamily Parreysiinae from South and Southeast Asia [separate FASTA file].<b>Supplementary Figure:</b><b>Figure S1.</b> [PDF and TRE files] Maximum likelihood phylogeny based on the reference <i>COI</i> barcode library of Asian Parreysiinae. The phylogeny was calculated using unique haplotypes, while all sequences were added to this tree at the post-calculation stage for visualization purposes. Each sequence name contains the following information: GenBank accession number | species name | collecting region (see Datasets S1 and S3 for sample detail and Dataset S4 for <i>COI</i> gene sequences). The black numbers near nodes are bootstrap support values of IQ-TREE v. 1.6.12. The scale bar indicates the branch length (substitutions per site). The titles of new sequences from Assam are red (colors only in PDF file).<b>Supplementary Tables:</b><b>Supplementary Table S1.</b> The <i>COI</i>-based uncorrected p-distances (mean ± standard error estimate, %) between species in the tribe Parreysiini [separate PDF file].<b>Supplementary Table S2.</b> The <i>COI</i>-based uncorrected p-distances (mean ± standard error estimate, %) between species in the genus <i>Lamellidens </i>[separate PDF file]<i>.</i><b>Supplementary Table S3.</b> The <i>COI</i>-based uncorrected p-distances (mean ± standard error estimate, %) between species in the genus <i>Trapezidens </i>and <i>Balwantia soleniformis </i>[separate PDF file]<i>.</i><b>Supplementary Table S4.</b> The <i>COI</i>-based uncorrected p-distances (mean ± standard error estimate, %) between species in the genus <i>Indonaia </i>and <i>Pseudoscabies scobina </i>[separate PDF file]<i>.</i><br><b>Cover Image:</b><b><i>Cover image:</i></b> Living topotype of <i>Assamnaia involuta</i> (Hanley, 1856) from a shallow oxbow lake in the Dhansiri River valley, Golaghat, Assam, 26 March 2022.
