ABSTRACT.-Serrasalmus hastatus, a new species of piranha with a highly compressed, deep body is described from the Rio Negro of Brazil. It is diagnosed by its nearly straight dorsal head profile in combination with a pigmentation pattern that includes thin, vertically elongate spots and thin stripes. S. altuvei Ramirez and S. compressus Jegu et al. are compared with the new species, as well as with each other.
