CLASSIFICATION OF A COMMON CUPPED OYSTER FROM SOUTHERN CHINA
To resolve the taxonomic status of a small cupped oyster from southern China, we collected and sequenced oysters from 20 sites in China along with sister species from other parts of the world. A total of 187 oysters were sequenced for 2 fragments belonging to the mitochondrial 16S rRNA and cytochrom...

C. angulata has a wide distribution in southern China, ranging from Zhejiang to Hainan, with the Yangtze River separating it from Crassostrea gigas in northern China.

Sequence divergence between C. angulata and C. gigas, 1.05-1.32% in 16S and 2.22-3.37% in COI, is higher than that between the most divergent populations of a Crassostrea species (C. virginica, 0.51% in 16S and 2.04-2.22% in COI), but considerably lower than that observed between two closely related sister species (2.11-2.37% in 16S and 9.32-10.11% in COI, between C. gigas and Crassostrea sikamea). This finding and the fact that the two oysters live in the same region with slightly different biological characters but can hybridize without any difficulties suggest that C. angulata should be considered a subspecies of C. gigas.
