Dysaethria diffiniaria Walker stat. rev. & comb. n.  
Erosia diffiniaria Walker, 1861, List Specimens lepid. Insects Colln Br. Mus., 23: 852.

Diagnosis and taxonomic notes.
The identity of diffiniaria was only established after the colour plates had been, prepared, hence it is not illustrated. It resembles grisea and warreni, and dissection is necessary for identification. The type (UM Oxford) proved to be male, not female as in the original description, with the abdomen glued and damaged, with much of the genitalia missing. Sufficient of the uncus remained to associate a male from Bangka I. with the type. The uncus tube is slender, the distal processes weak. The valves extend well beyond the apex of the uncus and are apically broad with a marked lobe. The aedeagus is much smaller than in the other two species and lacks cornuti. The species has been placed erroneously as a synonym of conflictaria (as listed by Nielsen, Edwards & Rangsi (1996)).

Geographical range. Borneo, Bangka I. (E. of Sumatra).

Habitat preference. The type is the only Bornean specimen, taken in Sarawak by A.R. Wallace, probably from a lowland locality.
