Species of the anthozoan order Zoantharia (=Zoanthidea) are common components of subtropical and tropical shallow water coral reefs. Despite a long history of research on their species diversity in the Caribbean, many regions within this sea remain underexamined. One such region is the Dutch Caribbean, including the islands of St. Eustatius, St. Maarten, Saba, Aruba, Bonaire, and Curaçao, as well as the Saba Bank, for which no definitive species list exists. Here, combining examinations of specimens housed in the Naturalis Biodiversity Center collection with new specimens and records from field expeditions, we provide a list of zoantharian species found within the Dutch Caribbean. Our results demonstrate the presence at least 16 described species, including the newly described Parazoanthus atlanticus, and the additional potential presence of up to four undescribed species. These records of new and undescribed species demonstrate that although the zoantharian research history of the Caribbean is long, further discoveries remain to be found. In light of biodiversity loss and increasing anthropogenic pressure on declining coral reefs, documenting the diversity of zoantharians and other coral reef species to provide baseline data takes on a new urgency.

荷兰加勒比海的Zoantharia（Cndaria：Hexacorallia）和一种新的寄生虫

亚热带和热带浅水珊瑚礁的常见物种是Zoantharia（= Zoanthidea）。尽管在加勒比地区对其物种多样性的研究已有很长的历史，但该海域内的许多地区仍未得到充分检查。其中一个地区是荷兰加勒比海地区，包括圣尤斯特休斯岛，圣马丁岛，萨巴岛，阿鲁巴岛，博内尔岛和库拉索岛，以及萨巴银行，这些岛屿均没有确定的物种清单。在这里，结合了对Naturalis生物多样性中心馆藏的标本的检查，新标本和野外探险记录的结合，我们提供了在荷兰加勒比海发现的真三生动物种类的列表。我们的研究结果表明，至少存在16种描述的物种，包括新近描述的Parazoanthus atlanticus，以及最多可能存在的四个未描述物种。这些新的和未描述物种的记录表明，尽管加勒比地区的动物学研究历史悠久，但仍有待进一步发现。考虑到生物多样性的丧失以及对不断下降的珊瑚礁的人为压力不断增加，记录黄化石和其他珊瑚礁物种的多样性以提供基线数据具有新的紧迫性。
