Diagnosis. With A. constricta, this is one of the smaller Bornean Anuga and
is distinguished by the rounded forewings and lack of conspicuous orange
patches. There is pronounced sexual dimorphism, the female having a fairly
typical grey fasciated forewing, but in the male this is very dark grey, the
fasciae obscure; the male hindwing, is also darker, grading to black towards the
base. In the male genitalia the aedeagus vesica lacks major cornuti, the uncus
is very reduced, the saccus has a slender, teat-like apical zone and the dorsal
processes of the transtillae are diagnostically crested.
Geographical range. Borneo.
Habitat preference. All specimens have been taken in lowland localities:
Ulu Temburong in Brunei, Bidi in Sarawak, and Pontianak (a long series) and
Samarinda in Kalimantan.
