Abstract
A new species of Phascolion (Phascolion) Cutler & Cutler, 1985 from the benthos off Exmouth, Western Australia, is described. Phascolion (P.) exmouthensis sp. nov. can be readily distinguished from other members of the subgenus by the presence of distinctive rectangular papillae which form a collar on the anterior trunk (a new morphological feature for sipunculans), and introvert hooks with non-recurved tips and a narrow base on the bulbous area immediately behind the mouth. The new species and P. (P.) ushakovi Murina, 1974 are the only two (out of 13) species of Phascolion (Phascolion) known from Western Australia.
