Dysaethria danum sp. n.
The smallest species of Dysaethria in Borneo, danum has grey wings
and facies similar to that of lilacina, though lacking the white flecks
associated with the posterior hindwing tail. The male genitalia are highly
distinctive. The uncus is bifid as in lilacina, though the processes are
shorter, broader. The setal area of the sacculus is more angular, and the tuft
of hair setae at the centre of the valve is stronger and closer to the costa.
The aedeagus has at its apex a curled spine, distally bifid.
