We describe a new species of carcinoecium-forming sea anemone, Stylobates birtlesisp. n., from sites 590-964 m deep in the Coral Sea, off the coast of Queensland, Australia. An anemone of this genus settles on a gastropod shell inhabited by a hermit crab, then covers and extends the shell to produce a chitinous structure termed a carcinoecium. Stylobates birtlesisp. n. is symbiotic with the hermit crab Sympagurus trispinosus (Balss, 1911). The nature of marginal sphincter muscle and nematocyst size and distribution distinguish Stylobates birtlesi sp. n. from other species in the genus. The four known species of Stylobates are allopatric, each inhabiting a separate ocean basin of the Indo-West Pacific. We also extend the known range of Stylobates loisetteae in the Indian Ocean off the coast of Western Australia.
我们描述了一种新的形成寄居蟹壳的海葵，名为斯氏寄居蟹海葵（Stylobates birtlesi），发现于澳大利亚昆士兰海岸外珊瑚海590 - 964米深处。该属海葵会附着在寄居蟹居住的腹足类贝壳上，然后覆盖并扩展贝壳，形成一种名为寄居蟹壳的几丁质结构。斯氏寄居蟹海葵与三刺共生寄居蟹（Sympagurus trispinosus，Balss，1911）共生。边缘括约肌的性质以及刺细胞的大小和分布将斯氏寄居蟹海葵与该属其他物种区分开来。已知的四种斯氏海葵分布区域不重叠，每种分别栖息于印度 - 西太平洋的一个独立海盆。我们还扩展了西澳大利亚海岸外印度洋海域的洛伊氏斯氏海葵（Stylobates loisetteae）的已知分布范围。
