DISTRIBUTION:

Antheraea (pernyi) roylii korintjiana (wingspan: males: 137-152mm; females: 127-151mm), often classified as a subspecies of roylei (correct spelling is roylii), flies as a montane species in
Sumatra;
Borneo = Kalimantan: Gunong Mulu, Sarawak (1790m); and
Peninsular Malaysia: Genting-Highlands (1500m), Tapah Hills (900m), Cameron-Highlands (900m).

Males can be dark brown, greyish-brown or orange, in all cases with yellow-orange fringe (broken into segments by darker wing veins), inwardly lined with darker scales. The male forewing apex is quite produced and the outer margin is very concave, but not so much as in A. lampei (see comparison images at bottom of this page. The dark post median line is also slightly concave in its upper reaches but straightens in a non-undualting fashion to the inner margin.

The veins are lightly suffused with relatively wide bands of darker scales, especially in the upper reaches of the median area. There is a relatively faint, diffuse, slightly darker, convex band running from the costa to the inner margin just outside the forewing ocellus.

I notice in the few specimens I have seen that the straight upper quarter of the am line is perpendicular to the costa, whereas in A. lampei this same section is convex and forms an acute (almost 45 degree) inward angle with the costa.

It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.

Antheraea (pernyi) roylii korintjiana and Antheraea lampei COMPARISON

The following composit image shows two recto images of Antheraea lampei males followed by a recto image of a third Antheraea lampei male. Superimposed on the right forewing of each of those three males is a verso image of an Antheraea (pernyi) roylii korintjiana male to show that male A. lampei have a much more produced forewing apex, a more concave outer margin (obscured by overlay), and a more produced forewing anal angle.

A left forewing Antheraea (pernyi) roylii korintjiana recto overlay on top of the second A. lampei image illustrates those same features and shows the differences in the am line, as mentioned above.

Ground colour varies for both species.
