Agathia
gigantea Butler
Agathia gigantea Butler, 1880, Ann. Mag. nat. Hist. (5),
6: 217.
Diagnosis. Males have strong grey and black submarginal bands, that on the
forewing narrower, irregular in course, that of the hindwing very broad,
especially towards the dorsum. Females resemble those of obsoleta and are
distinguished in the diagnosis of that
species above. A. solaria Swinhoe (see below) has narrower submarginal
bands with a more distinctly bilinear inner margin. Both sexes of gigantea have
the central indentations to this deeper, more obliquely ended.
Taxonomic notes. The taxon discisticta Prout (N.E.
Himalaya) proved on dissection to be a synonym of A. solaria Swinhoe
(Singapore) syn. n. rather than of gigantea. The male genitalia of gigantea
have the saccus longer, more bulbous than in solaria, the valves
relatively smaller, the serrate extension of the saccular angle narrower, and
the distal process of the costa reduced, subapical rather than apical. A.
solaria is recorded from the Himalaya, Singapore, and possibly Sulawesi.
Also closely related are A. affluens Prout from Bali and A. diversiformis Warren (N.E. Himalaya).
Geographical range. Java, Sumatra, Peninsular Malaysia (FRIM
colln), Borneo
Habitat preference. Both recently collected specimens
seen were from lowland forest in Brunei.
