Four new species of Spionidae (Polychaeta) from New Zealand, with comments on a syntype of <i>Spio aequalis</i> Ehlers from Chatham Island
Proceedings of the Biological Society of Washington
Four new species of Spionidae are described from New Zealand. Microspio maori is a widespread intertidal species occurring on both of the main islands. Microspio elegantula occurs intertidally in Wellington Harbor. Spio readi occurs in the intertidal zone of Wellington Harbor and from 50-105 m off the Otago Peninsula of South Island. Carazziella proberti closely resembles two Australian species and occurs off Otago in 122 m. Spio aequalis Ehlers is known only from its original find on Chatham Island. The syntype bears unusually large posterior branchiae.
