Taxonomy and Phylogeny of the Family Suberitidae (Porifera: Demospongiae) in California

This study presents a comprehensive taxonomic revision of the family Suberitidae (Porifera: Demospongiae) for California, USA. We include the three species previously known from the region, document two additional species previously known from other regions, and formally describe four new species as Pseudosuberites latke sp. nov., Suberites californiana sp. nov., Suberites kumeyaay sp. nov., and Suberites agaricus sp. nov. Multi-locus DNA sequence data is presented for seven of the nine species, and was combined with all publicly available data to produce the most comprehensive global phylogeny for the family to date. By integrating morphological and genetic data, we show that morphological characters may be sufficient for regional species identification but are likely inadequate for global classification into genera that reflect the evolutionary history of the family. We therefore propose that DNA sequencing is a critical component to support future taxonomic revisions.

Supplementary data

5 files:

1.Table_S1_archival.csv

Metadata for all samples investigated. Newly collected samples are associated with a \"collection ID\", which is a unique identifier used until the sample was voucher in a museum and given a voucher number. Samples with a museum voucher but no collection ID were loaned by the corresponding museum. the collection ID is also referenced in the raw spicule data file and in the Genbank flatiles, as these data were produced before the samples had museum voucher IDs. Genbank numbers are provided for samples with genetic data.

2.Raw_spicule_data.csv

Measurement data from all spicules. Lengths and widths are provided for each spicule; \"n/a\" indicates a measurement was not taken.

3.S3 occurance data.csv

Sampling effort and locations. Only species found in recent shallow-water surveys are shown. For all subtidal sites, the number of sampling dives is lis...
