Diagnosis. This and the next three species have very similar male genitalia, and absconditaria
can only reliably be distinguished from the next two by genitalic features.
The valve is quadrate with a single costal process only. The span is greater
than in the next two species, but the facies is a similar uniform pale, dull red
with faint fasciation and a small white discal mark on the hindwing that is
variably tinged with blackish brown.
Taxonomic notes. The complex was reviewed by Holloway (1982). Related species occur
eastwards to Fiji and New Caledonia. The whole group is probably referable to Trirachopoda
Hampson, though the unique holotype female of the type species lacks head
and abdomen. P. minorata dubiosa Prout (Taiwan) has similar facies: its
genitalia conform with those of this group, and, unlike the Bornean species,
there are very weak coremata on the fourth sternite. The male hind-tibia is much
shortened and bears a tuft of scales. Bornean material differs in uncus breadth
and vesica spining from typical Indian material.
Geographical range. Indian Subregion to Taiwan, Sundaland and the
Philippines.
Habitat preference. The species is recorded frequently from the upper
montane forest zone, over a range of 1620-2110m, on G. Kinabalu, and a singleton
was taken at 900m in lower montane forest on the limestone G. Api.
Biology. Yunus & Ho (1980) recorded Cinnamomum (Lauraceae) as a larval
host, but this record could well apply to one of the two lowland species
discussed next.
