Chrysoscota Hampson

Type species: auranticeps Hampson, New Guinea.

There is some similarity to Blavia in the brown colour and general shape, but the forewings are more elongate, less squared distally, and marked with paler patches. The venation arising from the cell is reduced to eight, but the branching triplet in the radial sector has the terminal bifurcation posterior rather than anterior. The hindwing has a bifurcate system arising from the posterior angle of the cell, rather than a single vein. The fore-femora are dilated. The male genitalia have the saccus weakly bilobed. The tegumen is much narrower on each side than in Blavia. The aedeagus vesica is generally and often coarsely scobinate in irregular fields. The male eighth abdominal segment is short, with shallow lobing on anterior and posterior margins. The female genitalia have the ductus and bursa long, the former sclerotised towards the base and the latter armoured except for an immaculate apical section with numerous thorn-like spines.

The genus ranges through the Indo-Australian tropics from Sundaland to New Guinea and Australia, but is most diverse in New Guinea and adjacent islands.
