The Hesperiini or branded grass skippers[1] are a tribe in the Hesperiinae subfamily of skipper butterflies.

They are known as branded grass skippers because all the males in this tribe feature a black diagonal brand of scales on their forewings that exude pheromones to attract females.

[1] Some subspecies of Hesperiini, such as Thespius Maacki, are found in high-altitude grasslands in areas like Araçatuba Mountain in Paraná, Brazil.
