The family Hormathiidae Carlgren, 1932 is one of the largest families of sea anemones with ca. 130 species around the world, mostly in the deep sea. In Brazilian waters, only six species have been reported so far. Herein we record four hormathiids from deep-sea sites at the Potiguar Basin continental slope at Northeast Brazil. Monactis vestita (Gravier, 1918) and Phelliactis robusta Carlgren, 1928 represent the first records of both genera for the Brazilian coast. The new species Paraphelliactis labiata n. sp. is described. We also found another species of the genus, Phelliactis sp. The new species possesses fourth and fifth cycles of incomplete mesenteries, unlike all other Paraphelliactis species. These results increase the total number of hormathiid sea anemones in Brazil to nine and contribute to the knowledge of the Brazilian deep sea, still little explored.
霍氏海葵科（Carlgren，1932）是海葵中最大的科之一，全球约有130种，主要分布在深海。在巴西海域，迄今为止仅报道过6种。在此，我们记录了来自巴西东北部波蒂瓜尔盆地大陆坡深海站点的4种霍氏海葵。绒拟单歧海葵（Monactis vestita，Gravier，1918）和粗壮拟厚指海葵（Phelliactis robusta，Carlgren，1928）是这两个属在巴西海岸的首次记录。描述了新物种唇拟厚指海葵（Paraphelliactis labiata n. sp.）。我们还发现了该属的另一个物种，即拟厚指海葵属某种（Phelliactis sp.）。与所有其他拟厚指海葵属物种不同，新物种具有第四和第五轮不完全隔膜。这些结果使巴西霍氏海葵科海葵的总数增加到9种，并有助于增进对巴西深海的了解，巴西深海仍鲜有人探索。
