Abstract

A new species of Acrocirrus is described from shallow waters of Coconut Island in Kaneohe Bay, Oahu, Hawaii. Acrocirrus bansei sp. nov. is an Acrocirrus whose segment 13 (chaetiger 11) is modified and equipped with a heavy neuropodial acicular hook. This new species is most similar to A. frontifilis based on the presence of notopodial cirri, which have been, up to now, a unique feature of A. frontifilis. The species differ most notably by the absence of the notopodial cirri on the posterior chaetigers. A key to all recognized species of Acrocirrus is presented.
