This paper discusses and illustrates the 23 primnoid species collected by the R/V Okeanos Explorer in the US marine protected areas in the central and western Pacific, ranging from the Musician Seamounts in the north to American Samoa to the south, and the northern Mariana Islands to the west (CAPSTONE expeditions, 2015-2017). In situ photographs are provided for most species. Thirteen of the 23 species are described as new, as well as two new genera. One new genus, Macroprimnoa, possesses some of the largest polyps in the family. A dichotomous key is provided to facilitate comparisons among the 27 species of Calyptrophora. An update of the abyssal octocorallian species occurring deeper than 3000 m is provided, increasing that number from 39 to 49 species. The character of the articulating ridge, found on the distal edge of the basal body wall scales, is re-evaluated, resulting in four genera having this character state, and requiring the description of the new genus Pseudonarella.
本文讨论并阐述了由美国“奥基诺斯探索者号”（R/V Okeanos Explorer）在中太平洋和西太平洋美国海洋保护区收集的23种软柳珊瑚物种，其范围从北部的音乐家海山到南部的美属萨摩亚，以及西部的北马里亚纳群岛（2015 - 2017年“基石”探险考察）。文中为大多数物种提供了现场照片。这23个物种中有13个被描述为新物种，还有两个新属。其中一个新属Macroprimnoa拥有该科中一些最大的水螅体。文中提供了一个双歧检索表，以方便对27种Calyptrophora进行比较。本文还提供了对深度超过3000米的深海八放珊瑚物种的更新信息，该物种数量从39种增加到49种。对在基体壁鳞片远端边缘发现的关节脊特征进行了重新评估，结果有四个属具有这种特征状态，因此需要描述新属Pseudonarella。
