Diagnosis. The species is often confused with L. impressa , L. calra ( Walker, 1865) and L. chrysoscela due to similar wing patterns, but can be easily separated from them by forewings with three silvery white, parallel oblique bands; valvae broad at basal half, divided into two wide lobes at distal half; aedeagus with four digitate projections, among which one is densely covered with short spines.
