A new genus and species of octocoral with a calcium-carbonate skeleton, Naniporakamurai sp. n., is described from a shallow coral reef in Okinawa, Japan. Contrary to most octocorals, the skeleton is composed of crystalline aragonite as in blue coral Heliopora. The results of molecular phylogenetic analyses of sequences of mtMutS, COI, and ITS1-5.8s-ITS2-28S region suggest Nanipora gen. n. specimens should be included in order Helioporacea. Based on morphological results compared with other Helioporacea including the genus Epiphaxum (family Lithotelestidae), we establish the new genus Nanipora within Lithotelestidae. This is the first time that a close molecular phylogenetic relationship between Heliopora and a related genus within Helioporacea has been revealed.

在日本冲绳的一个浅海珊瑚礁中发现了一种新的具有碳酸钙骨骼的八放珊瑚，命名为村上文石珊瑚（Naniporakamurai sp. n.）。与大多数八放珊瑚不同，其骨骼由结晶文石构成，如同蓝珊瑚（Heliopora）。对线粒体MutS、细胞色素氧化酶亚基I（COI）以及内转录间隔区1-5.8s-内转录间隔区2-28S区域序列进行的分子系统发育分析结果表明，文石珊瑚属（Nanipora gen. n.）的标本应归入石珊瑚目（Helioporacea）。基于与包括附轴珊瑚属（Epiphaxum，石珊瑚科Lithotelestidae）在内的其他石珊瑚目的形态学比较结果，我们在石珊瑚科内建立了新属文石珊瑚属（Nanipora）。这是首次揭示蓝珊瑚与石珊瑚目内一个相关属之间存在密切的分子系统发育关系。
