Paradiopa Prout
Type
species: parthenia Prout.
This small Oriental genus consists mainly of species with rather narrow,
apically produced, marginally rounded forewings, irregularly and obliquely
fasciated more darkly; there is a sinuous submarginal array of diffusely darker
spots that appears to be diagnostic. The hindwings in most species have a
subbasal disc of paler colour, white in extreme cases. Paradiopa nyei Kobes
has a hindwing as in the larger Bornean species but has a reticulated forewing
more as in Iambia tessellata Prout.
The
male abdomen has the basal trifine hair pencils. The genitalia have the valve
narrow, straplike, with a corona; the harpe is simple, a slender curved spine.
There is no process from the valve costa. The aedeagus vesica is globular,
unadorned, or with a tongue of scobination running into it (albidisca).
In
the female (postfusca Hampson examined) the ovipositor lobes and eighth
segment are unmodified. The ductus has a short basal ring of sclerotisation; the
bursa is elongate, slightly asymmetric, weakly corrugate and finely scobinate
throughout.
