Description

As described in The Moths of Borneo, “the pale brown wedge dividing the forewing apex identifies both sexes of this species. The male has a distinctive loop containing leaden-grey on the dorsum at one third that is separated from an 8-shaped patch of a similar grey distal to the reniform by a zone of fawn speckles on black. The ventral constriction of the 8 is produced by a distal tooth from the reniform. The male hindwings are only slightly suffused blue basal to a clearly defined, narrow, pale blue postmedial fascia.” It has been recorded from Borneo, Peninsular Malaysia, India, Java, Lombok, Dammer, Thailand (VK), Hainan and Japan.
