北部湾位于我国南海北部，是典型的南亚热带海域，也是我国珊瑚类群分布的重要区域之一。然而，该海域柳珊瑚类群的系统分类调查仍较为有限，物种组成及分布资料有待进一步补充。为进一步完善北部湾近岸海域柳珊瑚多样性资料，于2023—2026 年以水肺潜水调查为主，并结合渔业作业中附带获得的柳珊瑚样本，对采集自北部湾近岸海域（3~38 m）多个站位的柳珊瑚样本开展形态分类鉴定和分布记录整理。通过观察珊瑚体形态、分枝类型及珊瑚虫排列方式，并结合光学显微镜和扫描电子显微镜的骨针形态分析，进行系统分类鉴定。结果显示，共鉴定出柳珊瑚8科14 属21 种，其中发现2 个中国新纪录种，冠状疣柳珊瑚Verrucella corona Grasshoff， 1999 和波恩等柳珊瑚Parisis poindimia Grasshoff， 1999，并进行了详细的形态描述。分布上，调查记录的柳珊瑚样本采集水深范围为3~38 m，多数样本采自15 m以内的浅水礁石或硬底质生境；不同调查区域的物种组成存在差异，其中斜阳岛、东锣岛和西鼓岛记录的分类单元相对较多。结合先前研究结果，整理北部湾近岸海域已报道柳珊瑚共计9 科18 属45 种。研究结果不仅丰富了我国柳珊瑚的多样性资料，也补充完善了北部湾近岸海域柳珊瑚的分布特征，为北部湾近岸海域相关生态和资源研究提供了数据支撑。

Abstract： The Beibu Gulf is located in the northern South China Sea and represents a typical southern subtropical marine region, as well as an important area for coral distribution in China. However, systematic taxonomic investigations of gorgonians in this region remain limited, and data on their species composition and distribution still require further supplementation. To improve the knowledge of gorgonian diversity in the coastal waters of the Beibu Gulf, gorgonian specimens were collected from multiple stations at depths of 3-38 m during 2023-2026, mainly through SCUBA diving surveys, supplemented by specimens incidentally obtained from fishing activities. These specimens were subjected to morphological taxonomic identification and distributional data compilation. Taxonomic identification was conducted based on colony morphology, branching patterns, polyp arrangement, and sclerite morphology examined using light microscopy and scanning electron microscopy (SEM). A total of 21 species belonging to 14 genera and eight families were identified in this study, including two species newly recorded from Chinese waters, Verrucella corona Grasshoff, 1999 and Parisis poindimia Grasshoff, 1999, both of which are described in detail. In terms of distribution, the gorgonian specimens recorded in this survey were collected from depths of 3~38 m, with most specimens obtained from shallow rocky reefs or hard-bottom habitats within 15 m depth. Species composition varied among different survey areas, with relatively more taxa recorded from Xieyang Island, Dongluo Island, and Xigu Island. By integrating previous records, a total of 45 gorgonian species belonging to 18 genera and nine families have been documented from the coastal waters of the Beibu Gulf. These results enrich the diversity data of gorgonians in China, supplement the distributional information of gorgonians in the coastal waters of the Beibu Gulf, and provide baseline data for future ecological and resource-related studies in this region.
