Diagnosis. The wings are a uniform pale green that is only lightly marked with dark
fasciae and discal rings, only the submarginals being prominent.
Taxonomic notes. The male genitalia are similar to those of the Indian O. pertusaria Felder,
a larger, more heavily marked insect, sharing a broad longitudinal zone of
scobination on the sacculus. However, the valve costa is more sinuous, the uncus
narrower, square-ended, with more elongate basal processes laterally but lacking
subapical lateral triangular flanges. The processes on the eighth sternite are
very slender, acute, rather than broad and rounded. The female has a strongly
sclerotised, marginally scrolled ductus and a distinctive crinkled zone at the
Geographical range. Borneo, Sumatra, Singapore, Peninsular Malaysia (Penang).
Habitat preference. Bornean material is from lowland localities.
