| Abstract |
Semele trindadis is a new species so far endemic to Trindade Island, a remote island in the north-western South Atlantic Ocean. The study is based on 17 specimens, including 2 with soft parts. The main character of this species is strong concentric sculpture. The anatomy of a young specimen is described, and it shows typical semelid features, but the retractor siphonal muscles, the palps, and the foot are small, the intestine has a single loop, and there is a distinctive arrangement of muscles in the siphonal chamber. This species is easily distinguishable as the only semelid, and even tellinoidean, from Trindade Island. |
