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.
