21mm. This species is a darker, less yellow brown than its
Bornean congeners, with distinct but diffuse dark patches just distal to the
postmedial on both wings between M3 and CuA2. The Bornean species is also
darker, less variegated, more uniform than the genitalically very similar R.
anaglyptica Prout (Java, Bali). The underside submarginal bands are not
prominent in anaglyptica but strong as in the other two Bornean species
in quadripunctata. The male genitalia of quadripunctata and anaglyptica
share possession of an unusually long digitate sacculus process, but with
the distal half of the valve more bulbous centrally in quadripunctata, resembling
more the Javan R. neonephrica Prout.
