GI: Rusicada combinans already on website
SS: Based on MOB key at https://www.mothsofborneo.com/part-15-16/scoliopterygini/scoliopterygini_5.php
Forewing reniform with posterior lobe larger, filled with paler grey or dark brown
Forewing antemedial irregular; hindwing brown; Oriental
Based on this, the posterior lobe is not larger; hence I am not sure this is combinans. In fact, it seems to me that the posterior lobe is smaller. In which case, it may be fulvida.
GI: Rusicada fulvida (Guenée, 1852)

The similar species to fulvida is privata. I have not been able to separate these using images reliably.

Similar species: Anomis privata: MOT. Not entirely clear whether privata and fulvida can be easily separated without genitalia.
For privata (MOB)
Hindwing margin more or less evenly rounded. Posterior half of forewing postmedial more or less straight, evenly concave.
For fulvida (MOB)
Average line of anterior part of postmedial more or less at right angles to the costa
