Diacrisia hypogopa Hampson,
1907, Ann. Mag. nat. Hist. (7), 19: 235.
Spilosoma hypogopa Hampson;
Holloway, 1976: 4.
Diagnosis. The species can be distinguished from other yellow Bornean taxa by the
dorsal black streak on the thorax in combination with cream-coloured antennae
and the extensive dark markings on the forewing dorsum.
Taxonomic notes. A series of specimens with much reduced black markings and a stronger
roseate suffusion, particularly in the female, on the forewing underside are
here considered to be a variant of hypogopa as there are no appreciable
differences in the male genitalia. Males of both forms are illustrated. The
lightly marked form is perhaps more frequent in open and disturbed habitats.
Geographical range. Peninsular Malaysia, Sumatra, Borneo.
Habitat preference. During the Mulu survey and in Brunei the species has
been taken infrequently in lowland forest and secondary vegetation. The highest
record is from 1200m on G. Kinabalu.
