Coral reefs provide a habitat for many marine organisms and support the safety, coastal protection, well-being, and food and economic security of hundreds of millions of people. The focus on coral species diversity cannot be overemphasized. One of them,
Astrogorgia, contains many marine natural active substances, and has important scientific research value and application prospects. Most of the current research on the active substances of the genus
Astrogorgia is based on unidentified species, and in-depth taxonomic studies are urgently needed. A total of 1185 samples were collected from 2014 to 2021 in the waters of Xiamen Bay. Herein, the morphological identification, electronic microscopy, and gene fragment sequencing methods were used for the taxonomic study. There are three species of
Astrogorgia identified, including
Astrogorgia lafoa,
A. arborea, and
A. dumbea. Among them,
A. lafoa and
A. arborea are newly recorded species in the waters of China.
A. lafoa is distributed in Qingyu Island,
A. arborea is distributed in Wuyu Island, and
A. dumbea is widely distributed in Baiha Reef, Qingyu Island, Wuyu Island, and Xiaobai Island. In this paper, the geographical distribution and the habits of 18 species of
Astrogorgia are summarized, and the evolution of family and genus classification of
Astrogorgia is discussed. The results enrich the geographical distribution information and coral species diversity records of
Astrogorgia in China.
