本文描述了一种海葵新种--卡哈奎合齿海葵Synhalcurias kahakui sp. nov.，2016年7月和2019年5月在大土岛和奄美大岛附近采集的标本。分别这些海葵被鉴定为属于Actinernidae科，因为它们有许多内腔完美的肠系膜，并被鉴定为属于Synhalcurias Carlgren，1914，因为它们有一个口盘，没有任何发达的裂片。虽然该属目前仅包含一个种，即秀丽合尾蜥（Synhalcurias elegans）（Wassilieff，1908），但我们的标本比上述物种小，肠系膜较少，柱上缺乏包囊电池，并且在肠系膜细丝上有两种类型的微碱性p-鞭毛。根据新种的发现，对合甲此外，我们重新描述了S。根据从日本收集的新标本。
We describe a new sea anemone species, Synhalcurias kahakui sp. nov., from specimens collected off Otouto-jima and Amami-oshima islands in July 2016 and May 2019. respectively. These sea anemones were identified as belonging to family Actinernidae due to their many endocoelic perfect mesenteries and identified as belonging to the genus Synhalcurias Carlgren, 1914 because they have an oral disc without any developed lobes. Though this genus presently accommodates only one species, Synhalcurias elegans (Wassilieff, 1908), our specimens are smaller than the aforementioned species, have fewer mesenteries, lack nematocyst batteries on the column, and have two types of microbasic p-mastigophores on the mesenterial filaments. These specimens are described as Synhalcurias kahakui sp. nov. In view of the new species, the diagnosis of genus Synhalcurias is revised. In addition, we redescribe S. elegans based on newly specimens collected from Japan.
