Mecodina
violacea sp. n.
 ,  17-20mm. The ground colour is a paler, pinkish violet-grey than
in the previous two species, such that the dark costal triangle of the forewing
submarginal and the darker dorsal bar associated with the hindwing submarginal
stand out more prominently, and the submarginal itself provides them with a
narrow white edging distally as does the postmedial to a larger extent basally.
The diffuse extension from the forewing costal triangle to the marginal angle,
prominent in the previous two species, is present but very faint. The male
genitalia share the basoventral bulge to the uncus of the previous two species.
The valves have a stronger curvature at the base of the ventral margin and are
relatively slightly shorter.
