Presence of a dark shading around the bipunctate discal mark, this tending to be more intense in Rivula basalis, than Rivula simulatrix, though the HW cleft near tornus of male is probably the better feature for separation.

Note: Presence of a dark shading around the bipunctate discal mark, this tending to be more intense in basalis, means this is likely to be this species, though the HW cleft near tornus of male is probably the better feature for separation. Provisionally identified as separation from R. simulatrix is best done by examining hind wing cleft in male adn/or genitalia. pnt807 examined for presence of cleft in HW.
