The forewings are a rich chestnut brown, with fine, paler, yellowish fasciae that are edged black on each side. The antemedial is only apparent as an oblique dash on the costa. The postmedial arises from the dorsum at about twothirds, extending obliquely in a gentle curve; convex distad, but converging on the distal margin. Just subapically it flexes sharply basad and then extends in a shallow sigmoid to meet the costa opposite where it left the dorsum. Close to the margin is a punctate submarginal, consisting of black dots with pale yellow lunules immediately basad. There are three oblique pale yellow dashes on the costa between the submarginal and the postmedial. The hindwings are a uniform dull brown. The markings are variable in intensity. The male dissected (slide 17670) has the postmedial somewhat irregular and broken; there is also a dark discal mark.

Taxonomic note. Poole (1989) retained innotabilis as the only (type) species of Thopelia Nye, a replacement name for Plotheia Walker, a junior homonym. However, it is a typical Rivula (see the generic account).

Geographical range. Borneo, Peninsular Malaysia.

Habitat preference. The original material was taken by A.R. Wallace in Sarawak, probably in the lowlands. The species has not been recorded in recent surveys.

Biology. The larva has been recorded from rice (Oryza sativa; Gramineae) in Peninsular Malaysia by Yunus & Ho (1980); this record was overlooked by Robinson et al. (2001).
