fasciated and bordered with reddish or dull purple. In phaeocrossa the

which has discal spots, but not as broad as in I. vacillata Walker
where discal spots are also inconspicuous.
Taxonomic notes. The male lacks a pouch on the second sternite. The genitalia,
particularly the valves, are elongate, large, though the aedeagus is only
moderate in size. The female bursa is complex, with extensive fields of spines
Geographical range. Peninsular Malaysia, Borneo, Hong Kong.

primary and secondary lowland forest, particularly dry heath forest; lower
montane forest at 900m on the limestone G. Api.
