Three species of Siphonalia Adams, 1863 (Gastropoda, Buccinidae) from China seas, with descriptions of two new species

Abstract

Three species of Siphonalia A. Adams, 1863 collected from the East and South China Seas are described and illustrated. Species were identified during re-sorting of the Buccinidae collection in the Marine Biological Museum, Chinese Academy of Sciences, Qingdao. Siphonal ia marybethi Parth, 1996, from South China Sea, is recorded from the coast of China for the first time. Siphonalia leei sp. nov., from off Kueishan Island, Taiwan Island, most closely resembles S. fusoides (Reeve, 1846), but differs from it in having a relatively small spire with a flattened profile, more recurved siphonal canal and much smaller adult shell size. In shape and sculpture S. nanshaensis sp. nov., from the Nansha Islands (Spratly Islands), is most similar to S. mikado Melvill, 1888, but that species differs from it in having a more angulate teleoconch whorl with irregularly spaced spiral cords, less constricted shell base, and small parietal tooth on the inner lip.
