We report one newly recorded species of the genus Cuspivolva (Gastropoda, Ovulidae) from the offshore waters off Xiamen, Fujian Province: Cuspivolva bellica (C. N. Cate, 1973). All the specimens were collected near the low-tide line and inhabited on the branches of gorgonian corals; and now they are deposited in the Tropical Marine Biodiversity Collections of the South China Sea Chinese Academy of Sciences (TMBC). The shell morphological features of this species were presented, along with its habitat and distribution. Differences between this species and similar species are compared and discussed. Until now, there are eight Cuspivolva species known from waters off China. The discovery of this new species further enriches the cowries diversity in Chinese waters. A list of Cuspivolva species known from Chinese waters is also given in the paper.
