Diagnosis. The male has modified venation as described in the generic account. The
female resembles Calletaera jotaria, but lacks a strong black discal
crescent on the forewing.
Taxonomic notes. Female material from the Moluccas and New Guinea is yellower in ground
colour than that from the Oriental Region, with a stronger double dark brown
spot at the angle of the forewing postmedial: this is referable to ssp. straminea
Warren. A male from Seram has the aedeagus cornuti longer, more slender, but
fewer. The holotype male of ssp. bismarckensis lacks cornuti but has the
vesica extensively convoluted and scobinate.
Geographical range. Indo-Australian tropics to Bismarck Is.
Habitat preference. The species is infrequent in lowland and lower
montane forest. During the Mulu survey it was commonest in the lower montane
forest on the limestone Gunung Api.
