The " amastris " species group

The species of this presumably monophyletic group share the following combination of morphological characters (whether they represent symplesiomorphies or synapomorphies remains to be determined):

1. Hindwing subcostal vein long, ending distad of an imaginary line traversing the disc at the bases of veins M1 and CuA2 (Fig. A) (see also fig. 3 in Eitschberger & Racheli, 1998). 2. Interneural yellow submarginal stripes on the hindwing below drumstick­shaped, the basal portion noticeably thicker than the distal one (Fig. B).

3. Extreme base of the hindwing costal cell below, behind the humeral vein, partly or totally yellow, silvery or white, never wholly dark.

4. Besides a few red or orange scales at the extreme base of the hindwing below, no red coloration on the wings above or below.
