Ptyonota
Hampson
Type
species: formosa
Hampson, Burma.
The forewings are strongly falcate apically, and distinctly fasciated in red and
grey, sometimes with blackish suffusion.
The male genitalia have distinct lateral lobes ventrally on the tegumen at each
side. The coremata are massive, the valves rounded, rather paddle-like as in
some Careini, but lack a costal process. The saccus is distally long and narrow
as in Erizada, but not so ampullate. The aedeagus vesica has two
diverticula, with several spines at the apex of the larger one and one at the
apex of the smaller one.
The female genitalia have a moderate ductus and an ovate, densely scobinate
bursa; the ductus seminalis arises from the centre of the latter.
The genus is restricted to the Oriental Region, containing the species
discussed below.
