基于对 Forcipulatacea 内未描述的类群的系统发育分析，从深海环境中描述了深海 forcipulatacean 海星的一个新科 Paulasteriidae?fam.?nov.。 Paulasterias tyleri?gen.?et?sp.?nov.在最近记录的南大洋东斯科舍海脊热液喷口处观察到。第二个物种，Paulasterias mcclaini?gen.?et?sp.?nov。在北太平洋的深海环境中观察到，距离热液喷口更远。这两个物种都是多臂的（有六到八臂），具有肉质体壁，以及发育不良或缺乏的口隆突。在这里，我们讨论了马先蒂的形态、摄食生物学和分类。
Based on a phylogenetic analysis of undescribed taxa within the Forcipulatacea, a new family of deep-sea forcipulatacean starfishes, Paulasteriidae?fam.?nov., is described from deep-sea settings. Paulasterias tyleri?gen.?et?sp.?nov. was observed at recently documented hydrothermal vents on the East Scotia Ridge, Southern Ocean. A second species, Paulasterias mcclaini?gen.?et?sp.?nov. was observed in deep-sea settings in the North Pacific, more distant from hydrothermal vents. Both species are multi-armed (with between six and eight arms), with a fleshy body wall, and a poorly developed or absent adoral carina. Here, we include discussions of pedicellariae morphology, feeding biology, and classification.
