Molecular data

Identical CO1 sequence data were obtained for the two specimens of the West Beach Tanais sp. analysed (GenBank accession numbers: MW991406 , MW991407 ; length 679 nucleotides, nt). Table 1 shows the genetic distances (K2 P, Kumar et al. 2016) between these data and Tanais dulongii sequences available in GenBank (NCBI 2021). Three CO1 partial sequences are available for specimens identified as T. dulongii , one from a specimen collected at Dania Beach, Florida ( Drumm 2010; 568 nt) and two from multiple specimens collected at Mindelo, Portugal, and Helgoland, Germany ( Larsen et al. 2014; 389 nt).

The West Beach Tanais sequence differs by only 2% over the 568 nt sequence published by Drumm (2010). The two shorter sequences for T. dulongii specimens published by Larsen et al. (2014) show a genetic distance of 13.6% from each other and are more than 20% distant from the Florida and West Beach specimens.
