10mm and 11mm. The species is closer in size to the type species than to corona, but closer in facies to the latter, having a less emphatically darker zone of submarginal fasciation on the forewing. On the hindwing underside, the paler areas are a more speckled grey than in the female of corona. The diagnostic features are in the genitalia, where the lamella postvaginalis has a more extensive, rounded margin than in corona, with a few more than six irregular spines distally and one or two shorter spines on a lateral expansion of the margin on each side. There is a slight lobe subbasally on the ductus of the paratype (illustrated), but this is barely evident on the holotype.
