Diagnosis. Rhotana sabaea is similar to R. latipennis Walker , R. crassa sp. nov., and R. hirashimai , sp. nov., all also from Borneo. It can be distinguished from these by the brown mark around the last subcostal sector of the forewings as well as the long pointed process and the serrated lobe on the apical part of the male aedeagus.
