this new subspecies the forewing ground is a somewhat golden brown as in discipuncta,
but more rectangular, narrow, and with purplish black fasciation, particularly
intense basal to the reniform, which is conspicuous and B-shaped as in the next
three species. The new subspecies has the costal process on the valve

Hayashi (2003) described and illustrated the larva in Japan. It is long,
slender, with a cryptic pattern of fine black, grey and white longitudinal lines

with rows of black dots. The prolegs on A3 only are reduced; A8 is not humped.
