14mm. The species is slightly larger than rostrilinea but with similar facies. The pale costal zone extends further, as the postmedial that defines its extent is more distal, less oblique, and it also adjoins a paler triangle basal to the oblique antemedial. The reniform is smaller, rounder. On the hindwing there is a more conspicuous and straighter pale mauve zone distal to the postmedial over the posterior half. The genitalia have the valves with the ventral angle at the distal end much more elongate and tapered than in rostrilinea, extending well beyond the costal angle, which is reduced, not marked by the distinct triangular process that arises at a right-angle to the costa in rostrilinea. The aedeagus vesica lacks the long distal diverticula with two cornuti (central and apical) seen in rostrilinea, but has a broader dorsal lobe that is ringed basally by a series of moderate but short spines.
