Diagnosis.
The two species have facies as in the generic account, but differ in size, hepatizans
being
distinctly larger, and wing shape, with hepatizans having
the margins much less dentate. The forewing margin in hepatizans
is
more acutely and distinctly angled centrally, with the portion anterior to the
angle more concave than that posterior to it; the reverse is the case in motisigna
Prout.
Geographical
range. Indian Subregion, Thailand (VK), Andamans, Sundaland, Sumbawa,
Sulawesi; there is a closely related species in New Guinea (kobesi
Zilli
& Hogenes, 2004).
Habitat
preference. Three out of the four specimens taken in recent surveys are
from montane localities: 1500m and 1920m on G. Kinabalu; 1618m on Bukit Retak in
Brunei. The fourth specimen was taken from lowland forest at 300m in the Ulu
Temburong of Brunei. Chey (1994) recorded the species as frequent in secondary
forest in the lowlands of Sabah.
Biology.
Bell (MS) described the larva, originally thought to be Lacera alope,
as dark, russet-brown, with black-rimmed, light orange spiracles. The head is
chocolate brown and yellow. The prolegs of A3 are very small, those of A4 much
larger. The setae arise from yellow dots. There are prominent, red and black
tubercles on A8. The description of the pupa does not mention a powdery bloom.
Bell
did not mention a host plant, but it is probably in the Leguminosae like Lacera
alope.
Wagatea
(now
Moullava)
of this family is pencilled on the margin of Bell’s typescript.
