separabilis Walker comb. n.
Syntomis separabilis Walker,
1862, J. Linn. Soc. Lond. (Zool.), 6: 90.
Trichaeta separabilis Walker;
Seitz, 1912-1913: 67.
Diagnosis. This species has five transparent patches on the forewing as in some Amata
species. It may be distinguished from Bornean Amata with white rings
to the abdomen by the undivided nature of the transparent area of the hindwing.
Taxonomic notes. The taxon major Rothschild from Sumatra, described as a race of separabilis,
is likely to prove synonymous with vigorsi Moore. The male genitalia
of separabilis indicate a sister relationship with chloroleuca Walker,
the two species sharing a rather small, evenly scobinate aedeagus vesica, an
asymmetrically produced dorsal margin of the juxta (a larger process in separabilis)
a broad, rather rounded uncus (narrower in separabilis), setal
patches laterally on the tegumen, and valves with a narrow apical process
(longer in separabilis). The saccus is also relatively long.
Geographical range. Borneo.
Habitat preference. During the Mulu survey the species came rarely to
light in the understorey of lowland alluvial forest and dipterocarp forest.
Specimens in the BMNH are also from lowland localities.
