摘　　要：Porcellanasteridae is a group of starfish that live in the deep ocean around the world. The type species of this family, Porcellanaster ceruleus Wyville Thomson, 1878, is cosmopolitan as well as polymorphic. The first record of its occurrence in the South China Sea is reported in this paper. One specimen was caught in the South China Sea on June 6, 2015 by trawl and identified to be a P. ceruleus. The morphological characteristics of this specimen are described and detailed pictures are provided. The discovery of this specimen further expands the distribution of P. ceruleus in the Pacific Ocean. The world distribution records of P. ceruleus and its synonymic species are reviewed in this paper.Porcellanasteridae is a group of starfish that live in the deep ocean around the world.
