ABSTRACT Using mitochondrial COI-5P and plastid rbcL sequences, as well as morphological characteristics, two new species of Solieriaceae are added to the flora of Bermuda. Specimens collected over the past two decades representing those distributed in the early exsiccata, Phycotheca boreali-americana as Eucheuma gelidium (= Meristotheca gelidium) are shown to be a unique species of Meristotheca, M. odontoloma sp. nov. A recent collection from a depth of 60 m off the islands is shown to be the same as a single specimen found in Bermuda in 1953 at 55 m and identified at the time as Agardhiella ramosissima. These deepwater collections are described as the second species in the new genus Tepoztequiella, T. muriamans sp. nov. Based on shared morphological characteristics, other collections of M. gelidium and A. ramosissima from the western Atlantic may require molecular analysis to determine if they represent either of the two new species. Our molecular investigations also confirmed that there are two species of Meristotheca from Lord Howe Island, Australia, and Meristotheca halymenioides comb. nov., based upon Mychodea halymenioides, is removed from synonymy with M. papulosa.

来自百慕大近海透光区和中光区的两种新种 Solieriaceae (Rhodophyta, Gigartinales)，Meristotheca odontoloma 和 Tepoztequiella muriamans

摘要 利用线粒体 COI-5P 和质体 rbcL 序列，以及形态特征，百慕大植物群中添加了两种新的茄科植物。过去二十年收集的样本代表了分布在早期 exsiccata、Phycotheca boreal-americana 作为 Eucheuma gelidium (= Meristotheca gelidium) 中的那些样本被证明是 Meristotheca, M. odontoloma sp. 的独特物种。十一月 最近从离岛 60 m 深处采集的标本与 1953 年在百慕大 55 m 处发现的单个标本相同，当时被鉴定为 Agardhiella ramosissima。这些深水藏品被描述为新属 Tepoztequiella T. muriamans sp. 中的第二个物种。十一月 基于共享的形态特征，M. gelidium 和 A. 来自西大西洋的 ramosissima 可能需要分子分析来确定它们是否代表这两个新物种中的任何一个。我们的分子研究还证实，有两种来自澳大利亚豪勋爵岛的 Meristotheca 和 Meristotheca halymenioides comb。nov.，基于 Mychodea halymenioides，从与 M. papulosa 的同义词中删除。
