The Giant leaf-footed bug is the largest member of its genus in its range, with a broadly flared pronotum that extends well past the abdomen and blunt bumps along its front edge. Males stand out for their swollen, leaf-shaped hind legs, used in bouts with rival males and in courting females, while females have plain, slender legs.

Like other leaf-footed bugs, it feeds only on plant sap and does not bite people; a closely related species in the same genus is documented as unable to pierce human skin even when handled roughly.
