A mega-cryptic species complex hidden among one of the most common annelids in the North East Atlantic
International audience We investigate mitochondrial (COI, 16S rDNA) and nuclear (ITS2, 28S rDNA) genetic structureof North East Atlantic lineages of Terebellides, a genus of sedentary annelids mainly inhabitingcontinental shelf and slope sediments. We demonstrate the presence of more than 25 species...

Summary: | International audience We investigate mitochondrial (COI, 16S rDNA) and nuclear (ITS2, 28S rDNA) genetic structureof North East Atlantic lineages of Terebellides, a genus of sedentary annelids mainly inhabitingcontinental shelf and slope sediments. We demonstrate the presence of more than 25 speciesof which only seven are formally described. Species boundaries are determined with moleculardata using a broad range of analytical methods. Many of the new species are common andwide spread, and the majority of the species are found in sympatry with several other speciesin the complex. Being one of the most regularly encountered annelid taxa in the North EastAtlantic, it is more likely to find an undescribed species of Terebellides than a described one. |
