Type locality: "Habitat in Mexici, Panamae, Brasiliae montibus, sylvis". Mexico selected by Thomas (1911a:140); however, Linnaeus's name Sus tajacu is based on the tajacu of Marcgraf, from Brazil, Pernambuco (Cabrera, 1961:319; Hershkovitz, 1963, 1987b) and this restriction of the type locality is adopted here.
