Diagnosis. The forewings
are approximately triangular, but with a rounded dorsum, a rich caramel brown
that is variably and lightly traversed by pale mauve fasciation (sometimes
barely evident). In the centre of the forewing at about two thirds there is
usually a marking that may consist of two small black or fawn ellipses or a
larger disc, emarginate anterobasally, again either black or fawn. The
hindwings are duller brown, with a doubly shallowly excavate zone of the margin
near the tornus where the fringes are paler.
note. No significant differences in the male genitalia were noted in
the joint range of the taxa brought into synonymy, though the species is
variable, particularly in the extent of the black marking in the centre of the
forewing. The type of lilach is in BMNH according to Poole
(1989) but has not been located.
range. Sundaland, Philippines, Burma.
preference. During the Mulu survey three specimens were taken in hill
dipterocarp forest at the foot (150m) of G. Mulu, but four were recorded in
lower montane forest at 900m on the limestone G. Api. Records from Brunei are all
from lowland forest except for one specimen from 1618m on Bukit Retak.
Biology. There are two
paintings of larvae attributed to Anereuthina in BMNH,
together with one of a pupa and a pupal specimen in a cocoon.
larvae shown are semi-loopers with the proleg on A3 considerably reduced, but
that on A4 only slightly so. The head and body have a reticulate pattern of
variably sized black rectangles in a pale grey matrix; the thickness of the
pale grey relative to the rectangles differs in the two illustrations. The pale
grey is marked orange in places, and there is more extensive orange in a saddle
across A1, on the sides of the prolegs, and in further saddles across A8, which
is strongly humped, and A9.
is in a silken cocoon within a leaf. The pupa lacks any powdery bloom.
host plant is Elaeis (Palmae) (Yunus & Ho, 1980; Robinson et al. 2001).
