Chionaema cruentata Talbot; Holloway, 1976: 3.
Diagnosis
This species could be confused with conclusa and malayensis but both sexes have a diagnostic black wedge between the discal spots or spot and the antemedial. The black edge to the postmedial is relatively straight, that of the antemedial convex basad, rather than concave, though angled basad just before it meets the costa. The male genitalia have the ventral extremities of the tegumen rugose; the aedeagus vesica lacks cornuti.
