Diagnosis and taxonomic notes. This member of the imparatalis complex is
characterised by an extensive white area in the medial zone of the forewing. The
genitalia of a much smaller Taiwan female dissected (slide 19043) indicate a
close relationship to imparatalis: the specimen may just represent a form
of that species. The holotype (Borneo) of semialbida lacks its abdomen
but may represent a similarly extreme form of G. confusata Walker. In the
light of this, records of semialbida from elsewhere should be reassessed.
Geographical range. Borneo.
Habitat preference. No material has been taken in recent surveys. The
original material is likely to have been taken in the lowlands.
