Oenospila
Swinhoe
Type species: flavifusata
Walker.
Species in this genus
have the forewing costa lined with white, prominent dark discal spots and
irregularly dentate reddish brown postmedials on both wings. There is a faint
antemedial on the forewing, and the margins of both wings also have red
markings. The male antennae are bipectinate, the pectinations long, untidily
adpressed to the shaft.
The male abdomen is
characterised by a central, more or less circular patch of large setae (Fig
238). The genitalia have a characteristically sclerotised costa to the valve,
with a central flap that is folded over in some taxa or a distal projection.
There is also a saccular process or harpe that can be large (e.g. in the O.
strix Butler group). There are small coremata. The vinculum is narrow,
often produced into a saccus.
In the female genitalia (flavifusata)
the ovipositor lobes are of the modified type. The ductus is narrow,
surrounded by a scobinate, U-shaped lamella vaginalis. The signum is large, a
sclerotised, flat ring joined by its inner margin to the wall of the bursa.
The biology of the type
species is described below.
The genus contains ten
species, ranging throughout the Indo-Australian tropics. The taxon oleraria Guenée
was misplaced in Oenospila (see next genus).
