Tamba pallidiplaga Swinhoe comb. n.stat. rev.

Zethes pallidiplaga Swinhoe, 1905, Ann. Mag. nat. Hist. (7), 15: 160.

Diagnosis

The facies is similar to that of Tamba lahera Swinhoe (p. 357), but the ground colour is more fawn, the pale hindwing postmedial is straight, the forewing basal block of green is narrower, more curved, and the apical one is partly broken by patches of ground colour rather than by an oblique white mark. The species is also similar to T. magniplaga Swinhoe which has a paler, more fawn ground, the basal band of the forewing is much narrower, and the apical brown block is much stronger and contains an ellipse of ground colour in the same position as the white mark of lahera.

Taxonomic note

Poole (1989), reflecting an unpublished synonymy in the collection arrangement in BMNH, placed pallidiplaga as a synonym of T. grisea Holland (Buru; Carnegie Mus.), but this is considered to be unlikely on examination of material from Sulawesi and Seram (slide 14379). He placed both taxa in Tropidtamba; their male genitalia indicated they should be combined with Tambaand are related to magniplaga, therefore Tamba grisea Holland is also comb. n.

Geographical range

Peninsular Malaysia, Sumatra, Borneo, Thailand (VK).

Habitat preference

In recent surveys a single specimen was taken in lowland forest at 300m in the Ulu Temburong of Brunei. There is also a specimen from Samarinda in the lowlands of Kalimantan.
