Diagnosis. The ground colour is white, heavily suffused and marked with dark grey
and black. The forewing medial area is obscured in both sexes, but in the male
the hindwing medial area is often white. The other two species are very similar
and best distinguished on genitalic characters. A distinctive feature of semiparata
is the presence of deciduous dark, wedge-shaped scales on the exterior of
the valves.
Taxonomic notes. The holotype female of semiparata is worn, has been extensively
repaired and lacks an abdomen. Hence association of it with more recently
collected series from the G. Mulu National Park is somewhat tentative, based on
matching of pattern elements still visible and on general rather blackish
coloration. Under such circumstances it was considered preferable to designate
the new species (below) as the generic type species.
Geographical range. Borneo.
Habitat preference. During the Mulu survey the species was encountered
frequently in lowland dipterocarp forest, partially that of low elevations on
the limestone G. Api, but also frequently on G. Mulu. Records from alluvial
forest were few, and there were none from heath forest.
