(x 1.56)

, 9mm. The forewing ground colour is almost white and the fasciae almost black, their edges always sharply defined. The postmedial is broader at the costa and dorsum but also curved, convex basad, concave distad. The submarginal is reduced to an almost semicircular patch based on the tornal half of the distal margin. The facies is similar to that of arcuata Hampson (Philippines) but this has male genitalic valves that taper and lack the features described below. The genitalia resemble those of trifascia and trifasciata but have the apex of the uncus sinuous, a more tapering, serrate valve apex and a diagnostic brush of setae at the centre of the valve costa.
