Arguda angulata Grunberg, 1913, Ent. Rundsch., 30: 104.
Diagnosis. Both sexes are a duller red than in vita. The forewing
antemedial is strongly curved, delimiting an almost circular basal area,
whereas this fascia is obscure in vita and diagnostically angled at one
third from the costa. The white discal spot is more prominent. The male
genitalia resemble those of Philippines races of vita in having the
aedeagus spur slightly shorter, more abruptly tapered and the uncus
without a bifurcate process (present in some Mindanao vita specimens).
Both processes of the valve are relatively short, the lower ones diagnostically
so. The asymmetrically placed process of the eighth sternite is relatively
short as in Philippines vita races.
Geographical range. Borneo, Peninsular Malaysia, Sumatra.
Habitat Preference. All specimens have been taken in lowland localities,
but the species is uncommon.
