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.

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.
