Bapta araeophragma Prout,
1934, Novit. zool. 39: 133.
Diagnosis. This species and L. juta Prout are very similar. In juta there
are approximately equal, diffuse postmedial and submarginal fasciae, those on
the forewing more or less straight. In araeophragma the postmedial is
strong, curved on the forewing, and the submarginal indistinct. In the male
genitalia juta is distinguished by a prominent dorsal lobe at the base of
the uncus and by the lack of a corematous pouch at the base of the valve. In the
females, araeophragma has the bursa generally scobinate, whereas in juta
there is a typical ‘mushroom’ signum.
Geographical range. Borneo, Peninsular Malaysia.
Habitat preference. Almost all specimens taken during the Mulu survey
were from the limestone Gunung Api. The species was common in the lower montane
zone at 900m, but also taken at 250m and 1200m. A single specimen was taken in
the lower montane zone of G. Mulu.
