Diagnosis

This and the next species, flava van Eecke, are very similar, but only flexilisana males have an androconial patch on vein Sc of the hindwing; this is darker than the rest of the wing. The two curved fasciae are slightly more basal in flexilisana, the medial one rather indistinct. In flava they are of equal prominence, relatively distal, with the hint of an antemedial/subbasal one that has black dots at one-third and two-thirds Bornean specimens off lava have a faintly darker discall*unule on the hindwing and have the vesica cornutus much reduced. The male genitalia are similar, but the uncus is shorter in flava, and also the saccus, such that the tegumen section is longer than the vinculum rather than the other way round.
