Omiosia
Hampson
Type species: fusipennana Walker, Borneo.
Omiosia is
another monobasic genus endemic to Borneo. It is only known from the male. The
wings are strikingly modified, the forewing with the costal margin obtusely
angled where the subcosta meets it (Fig 6f), and with the dorsal margin also
strongly convex, with an elliptical black patch of denser scaling within the
convexity. On the underside there appear to be rather narrow scales in the
position of this black patch. The hindwing is also modified, triangular, weakly
bilobed at the distal margin, one lobe being the slightly produced tornus. There
is an elliptical zone of rather pale grey narrow scales in the centre of the
upperside of the wing (Fig 60.)

The abdomen and genitalia
are typical of the complex, though the aedeagus vesica has a large, slender
cornutus.
