Diagnosis.
This is a small species with blackish wings crossed by a series of fine white
and diffuse grey fasciae that are mostly straight or angled. The forewing
reniform and hindwing discal spot are elongate ovals of white.
Taxonomic
note. Poole (1989) transferred this species to Catada Walker, reflecting the current curation in the BMNH
collection. Lödl (1999b) indicated that the placement in Catada
meeded
further investigation. The male abdomen is very different from that of Catada
species,
and has many features in common with Pangrapta;
it particularly resembles P. albiseriata (see above) in the structure of
the eighth segment and in the ornamentation of the aedeagus vesica, though it
differs in the presence of a curved spine arising from the valve sacculus. The
female genitalia are very similar to those of albiseriata except
the corpus bursae is more spherical.
Geographical
range. Borneo.
Habitat
preference. The species is uncommon, most material being from lowland
localities, the majority with forest, including swamp forest. One specimen was
taken at 1000m on G. Mulu in lower montane forest.
