SEM study of Sandersiella chilenica sp.nov. (Cephalocarida), with a review of the Integumentary Structures and Functional Adaptations in the Group

The Cephalocarid, Sandersiella chilenica sp. nov. from Coliumo Bay, Central Chile ( 36º 32' S lat.; 72º56' W long) is described. The new species was collected at only one bottom station (station 4) in a grid of 11 stations sampled monthly during 1982-83, with predominating fractions of fin...

The new species was collected at only one bottom station (station 4) in a grid of 11 stations sampled monthly during 1982-83, with predominating fractions of fine sand, silt and clay. Four other species of the genus are so far known (Sandersiella acuminata Shiino 1965, and S.kikuchii Shimomura & Akiyama, 2008, from Japan, S. calmani Hessler & Sanders 1973 from off Perú, and S. bathyalis Hessler & Sanders 1973, from Walvis Ridge, and off Namibia, SE Atlantic, and off Santos, Brazil).
