P-distances quantifying genetic variation within and between specimens and morphospecies.

The first sheet lists intra-specimen mean p-distances (number of base differences per site averaged across all sequence pairs comprising each specimen). P-distances between the groups of ASVs comprising each morphospecies are provided in the matrices in second sheet of the dataset; calculations within each taxonomic order were computed separately. Likewise, intra-morphospecies and inter-morphospecies p-distances are given in the third and fourth sheets, respectively. When a specimen or morphospecies only yielded a single ASV, p-distance could not be calculated (“N/A” cells in the spreadsheets). Only specimens morphologically-classified to the species level were included in p-distance analyses. (XLSX)
