25-29mm.
The species resembles the Javanese deruna Moore (= aequizonata
Grunberg) in facies, differing from the previous species in the much
greater curvature of the exterior of the two central fasciae, and
the narrower space between them. The male genitalia have narrower
cubile arms with finger-like terminal processes rather than spines;
the valves are straight with a sub-basal dorsal spur rather than
curved; the aedeagus vesica is broadly bilobed with a patch of fine
scobination subbasally.
