A phylogenetic analysis of representatives of the red algal genus Hypnea in the Cuban archipelago was carried out utilizing two genetic markers: plastid rbcL and the mitochondrial cox1. Percent of base pair differences and Bayesian analyses indicate the presence of three species of Hypnea in Cuba: H. musciformis, H. spinella, and H. cryptica. The species H. cryptica, first described from Brazil, is confirmed here for the island of Cuba. This first record for the island of Cuba expands the distribution of this species into the Caribbean Sea.

古巴呼吸困难（Cystocloniaceae，Rhodophyta）的分子系统发育分析

利用两个遗传标记：质体rbcL和线粒体cox1对古巴群岛的红藻属Hypnea的代表进行了系统发育分析。碱基对差异的百分比和贝叶斯分析表明古巴存在三种呼吸困难：musciformis，H。spinella和H. cryptica。首次从巴西描述的隐孢子虫H. cryptica物种在古巴岛得到证实。古巴岛的第一个记录扩大了该物种在加勒比海的分布。
