摘要描述了产于波多黎各和巴哈马群岛的两个新种。两个地点都没有发现。所有这三个不同，从以前描述的Ethelia种在拥有腹假根，以及具有广泛的腹薄壁组织的产物。在波多黎各西南部的浅水高波能地点和莫纳岛的暴露地点收集了厚皮埃利亚。该物种形成非常明显的橙子结壳，比任何其他Ethelia物种都厚。厚叶Ethelia crassa也具有突出的中叶静脉细胞。第二种波多黎各种，Ethelia magnieni，仅限于超过60米深度的栖息地，也形成厚的结壳，其特征是其非常小的皮质细丝，直径为3.0 μm。第三，Ethelia excrescens，是从深水巴哈马的栖息地，并具有背表面的预测以及广泛的薄壁组织腹侧的副产物。SSU DNA测序在E. magnieni和E. crassa确认了它们在属中的位置以及它们作为独立物种的地位。
Abstract Two new Ethelia (Etheliaceae, Rhodophyta) species are described from Puerto Rico and a third from the Bahamas. None were found at both locations. All three differ from previously described Ethelia species in possessing ventral rhizoids as well as possessing variably extensive ventral parenchymatous outgrowths. Ethelia crassa has been collected at a shallow-water, high wave energy site in southwestern Puerto Rico and at an exposed site at Mona Island. The species forms highly conspicuous orange encrustations that are thicker than any other Ethelia species. Ethelia crassa also possesses prominent mesothallial vein cells. A second Puerto Rican species, Ethelia magnieni, restricted to habitats greater than 60 m depth, also forms thick encrustations and is characterized by its very small cortical filaments, 3.0 μm in diameter. The third, Ethelia excrescens, is from deep-water Bahamian habitats and possesses dorsal surface projections as well as extensive parenchymatous ventral outgrowths. SSU DNA sequencing performed on E. magnieni and E. crassa confirmed their placement in the genus as well their status as independent species.
