Six new Ophryotrocha species are described from five whale-falls and two wood-falls off the southern Californian coast. Phylogenetic analyses based on the nuclear gene H3 and the mitochondrial genes COI and 16S using MrBayes and maximum likelihood analyses were performed on 40 dorvilleid taxa and one outgroup. Ophryotrocha batillus sp. nov. is morphologically identical to Ophryotrocha scutellus described from a shallow water whale-fall in the North Atlantic, although the two cryptic species differ genetically. Ophryotrocha langstrumpae sp. nov. is closely related in the molecular phylogenetic analyses to these two sibling species. Ophryotrocha flabella sp. nov. is similar to Ophryotrocha globopalpata, and although there are a few morphological differences, the genetic divergence is low between the two species. Ophryotrocha nauarchus sp. nov. is sexually dimorphic, with males having appendages on the first chaetiger. Ophryotrocha magnadentata sp. nov. and Ophryotrocha longicollaris sp. nov. are sister species in our molecular analyses, and together with O. nauarchus sp. nov. and O. flabella sp. nov. they fall within a clade that includes O. globopalpata and Exallopus jumarsi described from hydrothermal vents in the Pacific Ocean and Ophryotrocha longidentata from the shallow North Atlantic. Our results highlight the remarkable unknown diversity of deep-water habitats and the role of chemosynthetic ecosystems in the evolution of deep-sea life.
