This is an easy one, this tractor two-seat side-by-side biplane is the Alagoas designed by Villela Júnior The earlier monoplane he designed was the Aribu. It's that easy ....

In 1918, Villela Júnior realized the potential of the airplane as a military weapon and went on to design a surveillance single-engine plane, which he called Aribu. Owing to its excellent flight performance, the Brazilian Army purchased the aircraft. With the Army's assistance, Villela built another aircraft, which he called Alagoas, and this time it was intended for instruction. On November 11, 1918, the same day in which the end of the First World War was signed, the Alagoas made its maiden flight and the first members of the Military French Mission were hired by the Brazilian Army to organize its School of Aviation arrived in Brazil.
Captain Etienne Lafay, who later helped produce two aircraft in Brazil, was among this group. Lafay and engineer, Braconnot worked in the shops of industrialist, Henrique Lage, from the ship repair and shipping industries, and designed a single-engine biplane similar to the to the French Caudron G.3
