New Records of Ahermatypic Corals (Scleractinia) from the Hawaiian and Line Islands

A CRITICAL CHECKLIST of the 54 species of ahermatypic Scleractinia known from the Hawaiian Islands is given. Based on a collection of approximately 1,150 specimens from 186 stations, new records are documented for 42 of these species, including 19 new records for the Hawaiian Islands, 8 of these being new species. A synonymy, discussion, and distribution are given for each of the 42 species collected; those species new to the Hawaiian Islands are illustrated. This new checidist of species shows the Hawaiian deep-water Scleractinia to be an attenuated Indo-West Pacific fauna having a 48% endemic component, a 17% centralwest Pacific component, a 15% Indo-West Pacific component, and a 17% cosmopolitan component. Deep-water Scleractinia from two stations from Christmas Island (in the Line Islands) and one station off Johnston Atoll are also reported.
