Astygisa waterstradti (paratype)

Astygisa waterstradti(paratype)

11-17mm. This is a larger, more maroon red species than the previous, variable in the extent of white markings on the wings, from specimens with only a submarginal row of flecks on the forewing via those with a forewing marginal cloud to those with a white discal circle on the hindwing and marginal clouds centrally on both forewing and hindwing. The male genitalia are similar to those of stueningi and diagnosed in the description of that species. The female genitalia have the spined ridges of the ductus reduced to one or two; the lamella vaginalis is broader.
