Organopoda ?acmaea Prout

Organopoda acmaea Prout, 1938, Gross-Schmett. Erde, 12: 147.

Organopoda carnearia Walker sensu Holloway, 1976: 63.

Diagnosis

This species and O. acerbata Prout have the forewing discal mark dark: a dot in acmaea and a more indistinct transverse dash in *acerbata.*Otherwise, dissection of the genitalia is necessary to distinguish the two.

Taxonomic Notes

Males only have been seen from the type locality, and all Bornean and Sumatran specimens seen are female, hence the association is somewhat tentative.

In the females, the lamella antevaginalis is somewhat pouched, the pouch flanked by outwardly directed triangular processes.

Geographical range

Peninsular Malaysia, ?Borneo and Sumatra.

Habitat preference

Most specimens have been taken in the upper montane zone (1930m on G. Kinabalu, 1680m on Bukit Pagon in Brunei), but one was taken at 250m in dipterocarp forest on the lower slopes of the limestone G. Api during the Mulu survey.
