Amata prepuncta sp. n.
14-15mm. This species has facies as in borneogena but with a dark
brown spot set much more anteriorly in the yellow of the hindwing. The most
distal of the two posterior yellow spots of the forewing is narrower and more
oblique than in the two close relatives. The male genitalia have the valves
subequal and strongly tapering. The aedeagus vesica has a group of cornuti set
on a lateral lobe rather than on the main part, which may also bear a few.
