species: punctana Walker, Sri Lanka.
genus, misspelt Narasodes by Hampson
(1900) and many subsequent authors, currently contains the two species described
below and three others from the Philippines and New Guinea. Only the type
species can definitely be considered to belong to it and possibly metatroga
Hampson from the Philippines, though the male of this has a strongly bilobed
hindwing reminiscent of that seen in Garudinia
males. The forewings are rectangular-oval, with a distinctive tuft of scales
extending backwards from CuA more or less in the centre of the upperside of the
wing, and a fringe of scales extending backwards from an arcuate fold in the
postcubital part of the underside. The forewing facies consists of diffuse,
angular banding of pale red and yellow on a paler ground, sometimes with an area
of black scales at the tornus. The bone-coloured hindwing may also have black
scales at the margin. The scale tufts are not prominent in Sri Lankan material,
and this also often has a small black dot in the discal area of the forewing.
The venation was illustrated by Hampson (1900), and is reproduced in Fig 10d.

male genitalia have the valves rather flimsy except for thickenings along the
costal and saccular margins, and terminating in a small spur. The aedeagus has
sclerotisation in the ductus ejaculatorius, but otherwise the vesica lacks
conspicuous ornamentation. A very similar genitalic structure is seen in typical
Heliosia Hampson (type species jucunda
female genitalia have the ductus bursae long, parallel-sided, moderately wide,
extending into a corpus bursae that is broader than long, with some corrugation
at the point of entry of the ductus and a scobinate signum set to one side amid
a halo of much sparser scobination.
