Buzara saikehi sp. n.
28mm. This species is a member of the group where the process on the right of the tegumen is flexed upwards and the thorax has patagia that are rufous or yellow, and sometimes is more extensively of this colour. However, the facies of flavimargo is distinctive even within this group. The patagia are rufous, but the borders of the wings and apex of the abdomen are pale yellow, this being most extensive on the forewing. Only the type species of the genus, chrysomela, has extensive yellow on the wings, but this is a richer cadmium yellow and occurs in a band at the centre of the forewing. The rest of the wings is black, but this area on the forewing shows some variegation with vestiges of the pattern seen in other Bornean species. The yellow border of the forewing has diffusely darker submarginal spots, but only that between Rs and M1 is conspicuous. The shape of the wings is also distinctive, with the forewing costal margin shallowly concave over the basal two-thirds, the dorsal margin is more convex, and the tornus is curved rather than angular. The branches of the radial sector veins anterior to Rs are compressed together, but CuA1 opposite is strongly curved in an expanded area. The hindwing apex is somewhat produced, but rounded, the posterior two-thirds of the distal margin being shallowly curved. On the underside, the yellow areas are more extensive relative to the black, particularly on the forewing.

Buzara saikehi
(holotype; in FRC, Sepilok)

The male genitalia are very similar to those of
chrysomela and feneratrix, with larger valves than the more easterly, white-banded section of the flexed process group, but this process is long, slender, and the pair of processes on the left valve are also slender, relatively straight, and closely associated.

Holotype . [SABAH]: Ranau, Mamut, Mei, ’93 [Saikeh Lantoh et al.]. In FRC, Sepilok.

Geographical range. Borneo.

Habitat preference. The locality is in an area of disturbed (copper mine) lowland forest to the south-east of G. Kinabalu. The specimen was collected on a hill top (approx. 1000m) overlooking the canopy of a stretch of undisturbed hill dipterocarp forest.
