Pangrapta
albiscripta sp. n.
 10-12mm. This is a small species with black wings that appear
grey between the fasciae due to whitish irroration, except the medial band where
this is pale yellow. The forewing fasciae become increasingly angled from the
irregularly straight antemedial through the slightly angled antemedial, then the
medial, to the strongly but not sharply reflexed postmedial. The more broken
submarginal is irregular in course. On the hindwing the fasciae are more
sinuous, with a black band just interior to the submarginal being the broadest,
though variable in width; there is a distinctive white x-shaped discal mark. The
species resembles macariana Hampson to some extent but is much smaller, and also hylaxalis,
which is also large and lacks a white discal mark on the hindwing, having one on
the forewing. The male genitalia are also distinctive, with the uncus somewhat
bulbous and the valves very long, paddle-shaped with a slender basal part. The
aedeagus vesica is simple, transverse, with a single cornutus on the longer
side. The female genitalia are similar to those of albiseriata.
