Diagnosis. The forewings are a medium grey with slight variegation: a
broadly based darker triangle in the centre of the costa with a paler patch at
its apex; a submarginal row of darker dots increasing in size posteriorly. It
lacks the darker zones on the dorsum of the next species. A variant (see below)
has dark longitudinal streaking obscuring this variegation.
Taxonomic notes. Male and female genitalia indicate that grisea and
indica are conspecific; indica females have a large appendix
bursae, but otherwise the genitalia are very similar, with two conical signa in
the bursa and an unusual pad-like structure at the base of the ductus. Both
typical and the more streaky forewing forms (strigivenata
Hampson) are seen in Borneo as in Australia (Nielsen et al., 1996). The
N.E. Himalayan taxon
N.
triangularis
Gaede (ex Strand) is distinct, stat. n., and related to the Japanese
N.
costalis
Sugi.
Geographical range. Sri Lanka; India, Burma, Borneo, Sumbawa, Australia (ssp.
grisea).
Habitat preference. Three specimens have been taken at 1000m in the lower
montane zone of G. Mulu and a fourth at around 1600m on G. Kinabalu.
