Descriptions of four new species of the genus Reticunassa Iredale, 1936 (Gastropoda: Nassariidae) from the northeastern coast of Taiwan Island and the South China Sea

Abstract: In the present study, four new species of the genus Reticunassa Iredale, 1936 collected from Chinese waters are described and illustrated. Reticunassa hugokooli sp. nov., Reticunassa jungi sp. nov. and Reticunassa aureolineata sp. nov. were collected from the northeastern coast of Taiwan Island, whereas Reticunassa fuscofasciata sp. nov. was collected from the northeastern coast of Taiwan Island and the South China Sea. The four new species can be distinguished conchologically from other congeners mainly in protoconch, shell shape, sculpture, and coloration. These findings demonstrate that the biodiversity of this group in China might be largely underestimated.
