On the basis of morphological observations, life history and molecular phylogeny, Grateloupia yangjiangensis, which is similar to G. filicina, G. orientalis, G. catenata, and G. ramosissima in appearance, was re-examined. The results are as follows：（1） the auxiliary-cell ampullae of G. yangjiangensis were of Grateloupia type, thalli was fleshy and gelatinous in texture, and the erect axes were compressed; the cortex was 0.25–0.30 mm thick, consisting of five to seven outer layers, and there were five inner layers of triangular or stellate cells;（2） there was no filamentous stage in the development of the carpospores;（3） the ribulose-1,5-bisphosphate carboxylase/oxygenase gene（rbcL） sequence of four G. yangjiangensis examined showed that there was no intergeneric divergence among them, and for the phylogenetic tree, four sequences of G. yangjiangensis formed a single monophyletic subclade within the large Grateloupia clade of Halymeniaceae. In conclusion, G. yangjiangensis was a single species within the genus Grateloupia. This research provided criterion for identification and cultivation of G. yangjiangensis.

A few species in the genus Grateloupia （Halymeniaceae, Rhodophyta） have been investigated in detail with respect to morphological observations and molecular analyses. In this study, the au- thors document the vegetative and reproductive structures of two new species of Grateloupia, G. dalianensis *** et ***, ***, and G. yinggehaiensis *** et ***, ***. They both have the morphological character that carpogonial ampullae and auxiliary cell ampullae are the simple Grateloupia-type. The two species can be distinguished from other species of the genus by their distinctive morphological features respectively. Bused on ribulose-l,5-bisphosphate carboxylase/oxygenase （rbcL） gene sequences, the phylogenetic tree obtained in the study indicated that they are both embedded within the Grateloupia clade. G. dalianensis clusters a subclade with G. asiatica, and G. yinggehaiensis forms a single monophyletic subclade with G. hawaiiana.
