Rhodolitica occultagen. nov. et sp. nov. (Clavulariidae) is described from Cocos Island National Park, Pacific Ocean, Costa Rica. The species was found at various islets and rocky outcrops around the island, 20−55 m in depth. The genus is characterised by tubular, single, erect anthosteles interconnected by thin basal ribbon-like stolons on the surfaces of living rhodoliths. The anthosteles are devoid of fused sclerites, which are only present in the stolons. Coenenchymal sclerites are mostly spindles of various shapes, with a characteristic cylindrical warty type in the outer layer, crosses and radiates. Anthocodiae are armed with points, lacking collarets. Colonies and sclerites are red. Using an integrative taxonomic approach, we separate the new genus from similar genera through both morphological comparison and a molecular phylogenetic analysis. This research is a contribution to the knowledge of the octocoral biodiversity in Cocos Island and marine biodiversity in the eastern tropical Pacific.

红假单胞菌。十一月 等 十一月 （Clavulariidae）描述于哥斯达黎加太平洋的科科斯岛国家公园。在该岛周围的各种小岛和岩石露头发现了该物种，深度为20-55 m。该属的特征是管状的，单个的，直立的蚁寄主，由活的杜鹃石表面上的薄基带状茎相互连接。蚂蚁没有融合的巩膜石，仅在the茎中存在。肠间质硬脂岩主要是各种形状的纺锤体，在外层具有特征性的圆柱形疣状，横穿并辐射。腕足类动物有点，没有领子。菌落和巩膜是红色的。使用综合分类法，我们通过形态比较和分子系统发育分析将新属与相似属分开。这项研究为了解科科斯岛八角生物多样性和东部热带太平洋海洋生物多样性做出了贡献。
