It is found within the Atlantic Forest lowlands in South America.

Members of this species are more aggressive and will warn invaders by producing a rhythm with their wings that resembles soldiers marching.

Menezes noted that he found specimens of Synoeca septentrionalis in the Atlantic Forest.

In 2017, Mendes and Rogério Botion Lopes studied the specimens and determined them to be a separate species.

The main defining traits are the coloration, jaw, and abdomen.
