Abstract

<p>Large chemosynthetic vesicomyids are currently under revision and generic designations will change in the future. The notation of <i>Abyssogena</i> species in the tree follows the preliminary nomenclature of Krylova and Sahling (2010) <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0039994#pone.0039994-Krylova2" target="_blank">[47]</a> while other vesicomyid species appear under their published names. MAR species red (SMAR) and blue (NMAR). GoC = Gulf of Congo, GoM = Gulf of Mexico, EPR = East Pacific Rise. The trees were calculated with ARB software using PhyML (GTR substitution model, estimated proportion of invariable sites, four categories of substitution rates). Bootstrap values (1000 replicates) higher 70% are marked at the relevant branches. Scale bars represent 10% estimated base substitution.</p
