Gyrtona
proximalis Walker
Gyrtona proximalis Walker,
1863, List Specimens lepid. Insects Colln Br. Mus. 27: 90.
Diagnosis. This species is variable in forewing pattern but the forewings are
brownish grey when fresh as in the next three species rather than ashy grey as
in ferrimissalis Walker. The margin to the pale basal zone of the
forewing is oblique but curved rather than straight as in obliqualis and perlignealis;
it is transverse in inclusalis. The species is best distinguished by
characters of the genitalia: in the male the dorsal arm of the valve is
distinctively tapered, and the harpe is long; in the female the lamella
antevaginalis is finely setose with distinctive lateral lobes, and the bursa has
a small central signum.
Geographical range. Borneo, ?Peninsular Malaysia (specimen in collection
of H.S. Barlow but not yet dissected).
Habitat preference. During the Mulu survey the species was taken
infrequently in lower and upper montane forest on both G. Mulu and G. Api, with
singletons from low altitude forest on limestone and kerangas.
