Malagonia sundana sp. n. 
15mm, 16-17mm. The facies is very similar to that of the type species, except the forewing fasciae are more clearly defined, the postmedial straighter and diverging from the submarginal as it approaches the costa rather than converging slightly with it. In the male genitalia the uncus and saccus are shorter than in acypera and the process in the valve is less complex, perhaps through greater fusion of the saccular and costal components. The dorsal margin of the costal component is shallowly curved rather than strongly sinuous.

Geographical range. Borneo, Sumatra (HS / ZSM), Peninsular Malaysia.

Habitat preference. All eight specimens are from the lowlands, two at least from areas of undisturbed dipterocarp forest. Further material recorded by S.J. Willott (unpublished data) indicated a preference for the forest understorey and was slightly more frequent in logged forest samples. Chey (1994) recorded it frequently in lowland softwood plantations in Sabah.
