Systematic re-structure and new species of Sphaerodoridae (Annelida) after morphological revision and molecular phylogenetic analyses of the North East Atlantic fauna
[Abstract] Detailed morphological study of more than 2600 North East Atlantic (NEA) sphaerodorids (Sphaerodoridae Annelida) and phylogenetic analyses of DNA sequences of representatives of several identified morphospecies enforced changing the current systematic classification within the family allo...
