Diagnosis. The facies is superficially similar to some Rivula species in the fawn ground colour, and the oblique medial dark shade and dark marginal zone to the forewing. However, these overlie a more extensive series of fine, oblique, slightly wavy, faint reddish brown fasciae that also recur more lightly on the hindwing. The oblique medial shade is associated with the two of these fasciae that run just distal to the discal mark; the discal mark consists of two black dots.
Taxonomic note. Bornean material resembles in facies the Australian detersalis more than it does that from the Indian Subregion (digramma), but Nielsen et al. (1996) do not mention mansueta, only detersalis. Indian material has the forewings a more uniform pinkish fawn, with darker discal and postmedial marks tending to predominate over the oblique fasciation. In the male genitalia the saccular process (harpe) is more strongly flexed in Indian males and the juxta apex is not so distinctly bulbous in Bornean and Australian males.
Geographical range. Borneo, Indian Subregion, Burma, Peninsular Malaysia, Philippines, Sumbawa, Seram, New Guinea, Australia.
Habitat preference. Older material is from lowland localities. In recent surveys a specimen has been taken in an area of forest at Semongok, near Kuching, and three were recorded in dry heath forest at 15m in the Telisai area of Brunei.
