species: illibata Fabricius,
genus contains four large, allopatric Indo-Australian species that range from
India and Okinawa to the south-west Pacific (Holloway, 1979; Holloway &
forewing facies is a rather uniform violet brown, with weakly paler, crenate
fasciae and a prominent reniform. The trapezoidal mark is darker, variable in
shape amongst the species. The male genitalia have a domed uncus or one with a
superuncus. The valves are large, with a single corema. The valve processes have
bilateral symmetry, with a bifid costal one and a somewhat separated rod-like
saccular one. In the female, the antevaginal plate can be acutely bifid, broadly
based, but short, with a slender, asymmetrically forked process by the ostium.
larva of the type species is described below. The most easterly species, P.
prisca Walker, has been recorded as feeding on Decaspermum
by Robinson (1975) and Holloway & Miller (2003).
