DISTRIBUTION:

Manduca prestoni (males: 112mm; females: 125mm) flies in
Brazil: Amazonas (specimen type locality); Manicore;
Ecuador;
French Guiana: SGO Regina; and in
Bolivia: Santa Cruz: Andrés Ibáñez, Potrerillos del Güendá. Johan van't Bosch reports it from Mato Grosso, Brazil.

Ezequiel Bustos indicates it has also been taken in Argentina: Tucuman, and that it is likely also present in Salta and Jujuy.

"Very similar to Manduca lefeburii, but the forewing upperside transverse dark band that runs through the discal spot is narrower, less diffuse, and does not reach the outer margin. It ends about 2/3 the distance to the outer margin, and is represented by dark submarginal and marginal marks on veins M3 and CuA1. The more distal dark costal mark is more conspicuous than in Manduca lefeburii." CATE
