TUSKES 3808 Sioux Ave., San Diego, California, 92117, USA. E-mail: [email protected] Abstract Four genera of Calliostomatidae are known from the northeast Pacific, Akoya, Calliostoma, Otukaia, and Xeniostoma. Fifteen holotypes and all species are illustrated and diagnostic information presented. Approximately one third of the species occur most commonly below 100 m, some species have been collected in excess of 1,000 m. Akoya titanium (McLean, 1984) and A. bernardi (McLean, 1984) are recognized as synonyms of A. platinum (Dall, 1890). Confirmed diet of the species, which are known, includes primarily sessile invertebrates and diatoms. Key Words: Calliostomatidae, Calliostoma, Otukaia, Xeniostoma, Akoya northeast Pacific Introduction Although morphological and dietary differences between calliostomids and Trochidae were previously known (Hickman & McLean 1990, Perron 1975), it was not until DNA data indicated the group was distinct, that Calliostomatidae Thiele (1924) was widely accepted (Bouchet & Rocroi 2005, Williams et al. 2010). Members of Calliostomatidae occur nearly worldwide, exhibiting physical and habitat diversity. Comments regarding diet, reproduction, habitat and shell appearance are specific to those species of the northeast Pacific. The northeast Pacific spans multiple marine provinces (MP) including, the Arctic, Oregonian-Alaskan, and Californian, which collectively encompasses coastal Alaska (USA), British Columbia (Canada), Washington, Oregon, California (USA), and Baja California (Mexico).
