Diagnosis. This is a dark blackish brown species, the forewings of the male filled almost entirely by a blackish area from the base to about four fifths where it has a sharp postmedial boundary with an acute angle at one third from the costa that reaches to within 2mm of the margin. Posterior to this the boundary runs directly and obliquely to the dorsum, diagnostically sinuous and diverging from the margin to meet the dorsum about 5mm from the tornus. There may be a trace of a blackish submarginal within the paler area distal to this, and this is usually evident as a black bar at the dorsum. Both the sexes have the forewing apical lens distinctly darker from the white dots basad, forming a black triangle over the basal part of the lens that is conspicuous in specimens with a paler marginal zone; in rhombalis and the previous two species the more basal part of the lens is paler. Also, the basal part of the border of the subapical costal lens that is formed by the postmedial meets the costa at a much more acute angle than in any other Bornean species or rhombalis. Females have the black area of the forewing more as in the previous species, separated from the dorsum by a paler strip, but never with the even curvature of rhombalis, rhombaloides and luzonensis, always with a rounded angle at the junction with the submarginal, which extends to the dorsum faintly in the same manner as in the male.
Taxonomic note. The type material of all taxa is male. Bornean material has a more uniformly dark forewing than in material from other localities, where the marginal area is paler, slightly greyer. The course of the postmedial from the angle to the dorsum is also less strongly sinuous in Borneo. Subspecies eductalis (N.E. Himalaya; slide 19926) has the distal fringe of digitate processes that run submarginally round the apicoventral part of the valve with the processes concentrated over the basal section rather than dispersed irregularly throughout. Lödl (unpublished) has established that eductalis Hampson is a junior homonym within his global concept of Hypena and will need replacement. A male specimen from Sulawesi (slide 19938) has a more strongly contrasted forewing facies, with the distal areas paler, and the valves of the genitalia lack a fringe of digitate processes. This probably represents a distinct species.
Geographical range. N.E. Himalaya (ssp.eductalis); Borneo, Peninsular Malaysia, Sumatra (Lödl, 1999e), Java, Bali, Philippines.
Habitat preference. Males of the species have been recorded from 1200m to 1930m on G. Kinabalu (five specimens) and singly at 1780m on G. Mulu. Females are much rarer but have been more often taken in the lowlands, though that tentatively identified as mandarina by Holloway (1976) was taken at 1930m on G. Kinabalu.
