A total of 803 specimens of Syllinae were collected during August of 2014 in Bermuda by snorkelling or SCUBA diving in different substrates and depths (electronic supplementary material, table S2). Specimens were sorted at the Bermuda Institute of Ocean Sciences (BIOS) using a Nikon SM7 stereoscope and preserved in 96% ethanol for the subsequent molecular and morphological analyses. Further examination and identification were completed at Universidad Autónoma de Madrid (UAM) using an Olympus SZ 40 stereoscope and an Olympus CX 43 light microscope. Drawings were made to scale with a camera lucida attached to a Nikon Optiphot light microscope and from pictures taken with an Olympus CX41 light microscope. The width of specimens was measured at the level of the proventricle, excluding the parapodia.
For scanning electron microscopy, selected specimens were prepared on an Emitech K850 Critical Point Dryer, gold-coated with a Q150T-S Turbo-Pumper Sputter Coater and examined with a Hitachi S 3000N scanning electron microscopy (SEM) at the Interdepartmental Research Service (SIDI) of the UAM.
Vouchers for all newly collected specimens were deposited at the Museo Nacional de Ciencias Naturales (MNCN) in Madrid (Spain). Catalogue numbers, collection dates, locality and additional relevant information are listed in electronic supplementary material, table S2.
