Diagnosis.
This is the
largest of the Bornean species, the forewings are a darkish grey-brown with a
pale, straight submarginal. Some forms have the basal half of the wing more
blackish, bounded distally as an obtuse angle. When the white reniform is
present, the anterior and posterior lobes are approximately equal in size. The
male antennae have a node. The valves of the male genitalia are strongly
corematous and apically excavate.
Taxonomic notes. Bornean
specimens (the typical race) and, to a lesser extent, Javan ones, have the
ventral dorsal angle of the valve produced well beyond the dorsal apical angle.
In material from Sulawesi and the Philippines eastwards (ssp. furunculoides Pagenstecher)
the ventral angle is shorter than, or equal to, the dorsal angle. Most areas
have a uniform (typical) form and a form with the basal half of the forewing
distinctly darker. The holotype of basiferruginea Rothschild (Sumatra),
here brought into synonymy, is the latter form. The reniform is white
infrequently. E. antennata Moore (N.E. Himalaya) is probably the sister
species of ceneusalis, having a more elongate, slender dorsal part of the
valve, the ventral part being rounded and contiguous with a short, globose
corema; the harpe is relatively short.
The abdomen of the
type of invicta Walker is that of a limacodid, evidently glued on in
error, particularly as the moth is female and the abdomen male!
Geographical
range. Sundaland,
Philippines, Sulawesi to Queensland and Bismarcks.
Habitat
preference. The
species is frequent in the lowlands, found in both undisturbed forest and
secondary associations.
