We investigate mitochondrial (COI, 16S rDNA) and nuclear (ITS2, 28S rDNA) genetic structure
of North East Atlantic lineages of Terebellides, a genus of sedentary annelids mainly inhabiting
continental shelf and slope sediments. We demonstrate the presence of more than 25 species
of which only seven are formally described. Species boundaries are determined with molecular
data using a broad range of analytical methods. Many of the new species are common and
wide spread, and the majority of the species are found in sympatry with several other species
in the complex. Being one of the most regularly encountered annelid taxa in the North East
Atlantic, it is more likely to find an undescribed species of Terebellides than a described one.Read less <
