MORPHOLOGY
The descriptions below are on the genus level. For difference between the species we recommend to look at the pictures or look up the original species description.
External characteristics
Forewing length (mm): 19-22.
General morphology:
Antennae slightly shorter than half of length of forewing, apiculus stout, untapered. Forewing relatively narrow, hind margin longer than termen, apex almost square, termen more or less bulging out in upper half and weakly indented between veins CuA2 and 1A+2A. Hindwing with inner margin slightly longer than costa; termen wavy because indentations at apex and further down; tornal cilia elongate.
Wing coloration:
Upper side: Upper side forewing grey brown with indistinct markings but with straight pale line from mid costa to mid hind margin; tiny hyaline apical spots and in spaces r5, m1 and m2. Upper side hindwing largely white or creamy white with darker area at base, apex and along termen.
Underside: Underside forewing about as upper side, a bit paler and plainer. Underside hindwing clearly white with dark areas as on the upper side.
