olivescoides sp. n.
, 11-12mm. The species resembles P. olivescens Hampson
(Sri Lanka, S. India) closely in facies, the ground of the wings being a pale
straw yellow, shaded and marbled with slightly greenish brown. The forewing
fasciae are pale as in the ground colour, the postmedial acutely angled and the
antemedial curved, oblique. The reniform is slightly darker-centred than the
rest of the wing shading. The male genitalia have the long blade-like process on
the valve typical of the genus, but the other process is less rigid, narrowly
triangular, finely setose. Only females of olivescens were
available in BMNH, having a long, ribbon-like ductus bursae and two small,
oblique scobinate signa in the corpus bursae as in the type species. The latter
are present but more irregular in olivescoides,
but the ductus is considerably shorter.

preference. This is a lowland species, not recorded above 300m. It has been
taken in hill and alluvial dipterocarp forest, in dry heath forest and in
coastal associations. S.J. Willott (unpublished data) recorded it somewhat more
frequently in canopy samples than in understorey ones in lowland forest near the
Danum Valley Field Centre. Chey (1994) recorded it as frequent in lowland
softwood plantations in Sabah.
