A New Species of Boccardia (Polychaeta: Spionidae) from the Galapagos Islands and a Redescription of Boccardia basilaria Hartman from Southern California

Abstract

A new species of Boccardia is described from shallow subtidal coral heads of Academy Bay, Santa Cruz Island, Galapagos Islands. The species is a borer and related to other species from the eastern Pacific. Boccardia basilaria Hartman, a close relative of the new Galapagos species occurs in subtidal benthic habitats of the southern California continental shelf. The species is redescribed and several deficiencies in its original description are corrected.
