Abstract
Two new species, and , are described from the southeastern Brazilian coast, from 44 and 200-258 meters deep, respectively. This is the first record of the genus from Brazil. sp. nov. superficially resembles its Atlantic and Magellanic congeners, (Théel, 1886), Ludwig, 1886, and Pawson & Valentine, 1981, but it can be readily distinguished from these by a combination of characters of the sole ossicles and by the absence of midventral tube feet. n. sp. stands apart from all Atlantic and Southern Ocean species (Atlantic sector), including sp. nov., in having branched rods (thorn ossicles) and knobbed plates in the sole. A key and a synoptic table to all Atlantic and Southern Ocean (Atlantic sector) species of is provided.
摘要
两种新物种， 和 ，分别从巴西东南海岸44米以及200 - 258米深处被描述。这是该属在巴西的首次记录。新物种 表面上类似于其大西洋和麦哲伦同类物种，如 （泰尔，1886年）、 路德维希，1886年，以及 帕森和瓦伦丁，1981年，但通过结合足底小骨的特征以及没有腹中线管足，它可以很容易地与这些物种区分开来。新物种 与所有大西洋和南大洋（大西洋区域）的物种不同，包括新物种 ，其足底有分支杆（棘小骨）和带瘤板。提供了一个关于所有大西洋和南大洋（大西洋区域） 的物种的检索表和一览表。
