MORPHOLOGY
External characteristics
Male
Wingspan (mm): 54 (Grose Smith And Kirby, 1892).
Forewings: The forewing has on its underside wing surface a small yellow subapical spot (Pequin, 2021). Hindwings The hindwing is almost completely black and its underside is marked by a small yellow spot on the submarginal area (Pequin, 2021).
Female
The females generally have a different underside wing surface than the males, by being darker with broader margins on both wings (D'Abrera, 1982). The females have a yellow abdomen (Pequin, 2021).
Subspecies and variation
Six subspecies are described, of which three subspecies are found in Papua. There are a couple of variations in between the subspecies: the amount of black apical markings varies, the size of the small yellow subapical spot on the underside of the forewing, and the size of the small submarginal yellow spot on the hindwing underside (Pequin, 2021).
