Abstract

<jats:p>A new species of siphonostomatoid copepod is described from a hydrothermal vent in the Tofua Arc of the southwestern Pacific at a depth of 1018 m. <jats:italic>Chasmatopontius inflatus</jats:italic> sp. nov. (Copepoda, Siphonostomatoida, Dirivultidae) is defined and illustrated from specimens isolated from washings of invertebrates including gastropods, bivalves, and crustaceans collected from a hydrothermal vent field. A brief description of its habitat is presented. This new species can be distinguished from <jats:italic>C. thescalus</jats:italic>, the only known congener, by the greatly expanded mediodistal seta of the caudal ramus in the female, the three-segmented endopod of the female maxilliped, the smaller female body, not exceeding 0.9 mm in length, and the unique shape of the female genital double-somite.</jats:p>
