通过形态学观察和 rbcL 序列分析报道产自海南省文昌的红藻门海膜科蜈蚣藻属一新种：博鳌蜈蚣藻(Grateloupia boaoensis Wang et Luan sp. Nov.)。博鳌蜈蚣藻的藻体紫红色,表面光滑,软骨质,高15-40 cm；主枝侧枝均扁形,叶片状；分枝顶端呈剑形,厚度为400-800μm,由4-9层皮层细胞和髓部组成,髓丝纵走,错综交织；助细胞生殖枝丛为典型的 Grateloupia 型；囊果在主枝与分枝上均有分布并分布密集。在用rbcL 序列构建的系统树中,四个博鳌蜈蚣藻样品聚在一起并与莺歌海蜈蚣藻(G. yinggehaiensis)聚成一个小分支。通过形态观察和rbcL序列分析,认为博鳌蜈蚣藻和莺歌海蜈蚣藻的亲缘关系最近。

During macroalgae investigation, a new Grateloupia species from Wenchang, Hainan Province, South China, was discovered and named Grateloupia boaoensis Wang et Luan sp. nov. By using morphological observa-tion and molecular analysis, we determined that G. boaoensis was purplish red, cartilaginous and slippery in tex-ture, 15-40 cm high, with completely compressed and foliated axes with lateral branches and sword-shaped apex. The transverse sections were 400-800 μm thick consisting of 4-9 layers of cortex cells and solid medulla, and the medullar filaments were longitudinal and intertwined. The new species exhibited typical Grateloupia-type auxiliary cell ampullae. Cystocarps were densely distributed on both axes and lateral branches. The four G. boa-oensis sequences in this study were identical and formed a single monophyletic subclade with G. yinggehaiensis embedded in the Grateloupia clade based on ribulose-1, 5-bisphosphate carboxylase/oxygenase gene (rbcL) se-quences. G. boaoensis was considered most closely related to G. yinggehaiensis by morphological observation and molecular analysis.
