Hungry scale worms: Phylogenetics of (Polynoidae, Annelida), with four new species.

Polynoidae Kinberg, 1856 has five branchiate genera: Pettibone, 1984, Pettibone, 1985, Pettibone, 1985, Desbruyères & Laubier, 1988, and Miura, 1994, all native to deep-sea, chemosynthetic-based habitats. Of these, has two accepted species; Desbruyères & Laubier, 1988 (Atlantic Ocean) and Pettibone, 1993 (East Pacific Ocean). The goal of this study was to assess the phylogenetic position of , utilizing DNA sequences from a broad sampling of deep-sea polynoids.
