Diagnosis. (See P. obliviaria). Examination of the genitalia is
advisable to separate the two species with confidence.
Taxonomic notes. P. contrariata lacks the definitive Perixera features. The
uncus of the male genitalia is digitate as in the Trirachopoda group, but
the valve is elongate with a costal lobe, but also a saccular spur as in Cyclophora
and Streptopteron.
Geographical range. Sundaland, Andamans, Thailand, N.E. Himalaya, Taiwan,
Hong Kong.
Habitat preference. The species is uncommon and lowland. The two
specimens taken in recent surveys were from dipterocarp forest at 250m on the
limestone G. Api and from secondary and coastal forest at Seria in Brunei.
Biology. The species has been reared from Dalbergia (Leguminosae) in the
Andamans (unpublished IIE records).
