The fifth species was collected in 2001, and was found close to where the Solimões and Purus rivers link up in Brazil. The newly identified species, known scientifically as A. leptosome, has several distinguishing features, such as an elongated sensory cavity on the head, a sheath that covers part of the dorsal fin and a distinctive color pattern.
