Diagnosis and taxonomic
note. The species is only known from
females and resembles a much smaller uniformis, the forewings being pale
brown with a small discal dot. The genitalia have lateral pockets in the seventh
segment and an unusual expansion and sclerotisation of the ductus. The bursa is
divided into two as in clavata and aridoides, but scobination is
only vestigial in the distal part. The status of the taxon formosibia from
Taiwan needs investigation, but it is unlikely to be conspecific.
Habitat preference. The
original two specimens were taken in S.E. Borneo by Doherty.
