Antheraea platessa Rothschild

Attacus jana Stoll, 1782, Uitlandsche Kapellen, 4: 220.

Antheraea andamana Moore, 1877, Proc. Zool. Soc. Lond., 1877: 602.

Antheraea jana platesse Rothschild, 1903, Novit. Zool., 10: 311.

Antheraea jana fusca Rothschild; Allen, 1981: 117; Barlow, 1982: 50; Lampe, 1985: 13.

The male is dull brown with crenulate fasciae and a broad, diffuse, dark medial band on each wing.

The apex and tornus of the forewing and the marginal zone of the hindwing are sometimes broadly paler.

The female has more clearly defined submarginals, with the zone distal to them paler than the ground.

The ocelli have broad transparent areas.

The original illustration of jana, if accurate, shows a male insect smaller and yellower than those generally attributed to that species; however, the course and diffuseness of the forewing medial is compatible.
The name andamana Moore is applicable to this taxon should the current concept of jana prove erroneous. However, if the type of the latter can be proven lost, it would be in the interest of stability to designate the holotype of andamana as neotype of jana.
Nässig (1992; reviewed also by Nässig et al. (1996)), after a close examination of the original description and illustration of jana, concluded that it was definitely a different species, and also decided that Sundanian material was not referable to andamana Moore (Andamans). The oldest available name is platessa Rothschild. Holloway et al. (1996) suggested that the presence of the species on Sulawesi is likely to be due to human introduction.
