Subspecies and Distribution. C. p. paca Linnaeus, 1766 — E & S Colombia, Venezuela, the Guianas, and E Brazil to Paraguay, N Argentina (Misiones and Corrientes provinces), and Uruguay. C. p. guanta Lonnberg, 1921 — W Brazil, Ecuador, Peru, and N Bolivia. C. p. mexianae Hagmann, 1908 — E Brazil, mouth of the Amazon in Para State. C. p. nelsoni Goldman, 1913 — E & S Mexico (Atlantic slope lowlands from San Luis Potosi State to Yucatan Peninsula), then through Central America to N Costa Rica. C. p. virgatus Bangs, 1902 — W Costa Rica, through Panama to N & W Colombia. It is also naturally present in Trinidad and Tobago Is (subspecies unknown), but it was extinct in Tobago I long ago due to overexploitation by Amerindians. They also introduced the Lowland Paca (nominate subspecies) from Venezuela into Curacao I, the largest of the Netherlands Antilles. In the 20" century it was successfully introduced into Cuba from Mexico, so it should belong to the Mexican subspecies nelson in Cuniculidae

Distribution. Central Amazon Basin of Brazil (Amazonas and Para states), from the left bank of the lower Rio Negro to the mouth of the Rio Pitinga N of the Amazon River axis, and from the lower Rio Madeira to lower Rio Tapajos on the S side of the main Amazon trunk. in Echimyidae
Distribution. Central Amazon Basin of Brazil (Amazonas and Para states), from the left bank of the lower Rio Negro to the mouth of the Rio Pitinga N of the Amazon River axis, and from the lower Rio Madeira to lower Rio Tapajos on the S side of the main Amazon trunk.
Distribution. SE Bolivia (departments of Tarija and Santa Cruz), N Argentina (provinces of Jujuy, Salta, Formosa, and Chaco), Brazil (W of the Rio Parana— through the N of Mato Grosso State into SW Goias, and Mato Grosso do Sul states), and Paraguay (E of the Rio Paraguay as far as the mouth of the Rio Parana). Its range to the west in Bolivia is poorly known; it would seem that it is absent from the Bolivian Chaco as it is from the adjacent Paraguayan Chaco west of the Rio Paraguay. There is no evidence to date that the Yungas populations in SE Bolivia and NW Argentina are continuous with the population in Brazil and Paraguay to the E. in Cebidae
