male.gif (860 bytes)male.gif (860 bytes)45-52mm, female.gif (844 bytes)female.gif (844 bytes)55mm. This is the smallest Bornean species. It is a rich rufous brown with more orange highlights and distinctive orange fringes. The ocelli are relatively small compared with celebensis and moultoni, particularly in the female where the nacreous zone is reduced to a point. The submarginal of the forewing curves basad at the dorsum slightly instead of running approximately straight to meet it as in moultoni; it is obscure in the male but a distinct, fine, dark line in the female. The male genitalia are typical of the frithi complex and offer no diagnostic features.
