bornemontana sp. n.
Spilosoma biseriata Moore
sensu Holloway, 1976: 4.
17-18mm. The wings and body are pale dull orange, the abdomen and dorsal
half of the hindwings suffused pink, and the patagia strongly edged in pink. The
forewing fasciae are as illustrated, the antemedial only weakly angled, the
postmedial separate, sinuous, usually weak or broken opposite the discal area.
Kinabalu material (not included in the type series) is paler, usually with a
submarginal spot distal to the break in the postmedial. The male genitalia are
typical of the group. Other pale orange or yellow species (biseriata Moore,
Andamans; kannegieteri Rothschild, N. Nias; flavens Moore, N.E.
Himalaya) have the forewing antemedial more angled and variable development of
black spotting on the hindwing.
