DOI：10.2216/12-005.1我们重新评估了以前归属于D. ciliolata和D.具细齿的。这两个分类群长期以来一直被认为广泛分布在热带至暖温带海域。然而，最近的分子数据提供了证据表明D. crenulata构成了至少4种的复合体，地理分布有限。基于这些结果和仔细的形态学检查，我们将D。crenulata sensu lato转化为D. crenulata sensu stricto，D. jamaicensis和D. canariensis和D.新种Pleiacantha sp. nov.形态学分析表明，这些物种是由细微的形态差异。与D. crenulata sensu lato，广布于热带的D.通过DNA数据证实了ciliolata的存在。此外，psbA序列分析没有提供分离D. tetralis和D. plectens从D.纤毛动物
Tronholm A., Afonso-Carrillo J., Sansón M., Leliaert F., Fernández-García C., and De Clerck O. 2013. Taxonomy of the Dictyota ciliolata–crenulata complex (Dictyotales, Phaeophyceae). Phycologia 52: 171–181. DOI: 10.2216/12-005.1 We reassessed the taxonomy of dentate Dictyota species formerly attributed to D. ciliolata and D. crenulata. Both taxa have long been assumed to be broadly distributed in tropical to warm-temperate seas. Recent molecular data, however, provided evidence that D. crenulata constituted a complex of at least four species with restricted geographical distributions. Based on those results and careful morphological examination, we split D. crenulata sensu lato into D. crenulata sensu stricto restricted to Pacific Central America, D. jamaicensis with a tropical amphi-Atlantic distribution and D. canariensis and D. pleiacantha sp. nov. from Macaronesia. Morphological analysis showed that these species were distinguished by subtle morphological differences. In contrast to D. crenulata sensu lato, the wide tropical distribution of D. ciliolata was confirmed by DNA data. In addition, psbA sequence analysis did not provide evidence to segregate D. menstrualis and D. plectens from D. ciliolata.
