  • Penaeus (Melicertus) aztecus aztecus  Perez-Farfante, 1969. Before 1939 this species was not distinguished from the other East American species of the subgenus Farfantepenaeus, all of which were then indicated as Penaeus brasiliensis. In 1967 two subspecies of P. aztecus were recognized, which at present are considered good species: P. aztecus and P. subtilis.

    Interest to Fisheries
    Off North Carolina this is the most important Penaeus species. Also along the north and east coast of the Gulf of Mexico it is of great commercial value, although sometimes surpassed by P. setiferus ; the grounds off Texas are by far the most important. In 1976, 61 873 t of the species were landed in the U.S.A. Aquaculture experiments with P. aztecus have been undertaken in the U.S.A. The total catch reported for this species to FAO for 1999 was 61 206 t. The countries with the largest catches were USA (61 206 t).
